+//  Support for variable argument lists in freestanding edk2 modules.
+//
+//  For modules that use the ISO C library interfaces for variable
+//  argument lists, refer to "StdLib/Include/stdarg.h".
+//
+//  VA_LIST  - typedef for argument list.
+//  VA_START (VA_LIST Marker, argument before the ...) - Init Marker for use.
+//  VA_END (VA_LIST Marker) - Clear Marker
+//  VA_ARG (VA_LIST Marker, var arg type) - Use Marker to get an argument from
+//    the ... list. You must know the type and pass it in this macro.  Type
+//    must be compatible with the type of the actual next argument (as promoted
+//    according to the default argument promotions.)
+//  VA_COPY (VA_LIST Dest, VA_LIST Start) - Initialize Dest as a copy of Start.
+//
+//  Example:
+//
+//  UINTN
+//  EFIAPI
+//  ExampleVarArg (
+//    IN UINTN  NumberOfArgs,
+//    ...
+//    )
+//  {

+//    //
+//    // Initialize the Marker
+//    //
+//    VA_START (Marker, NumberOfArgs);
+//    for (Index = 0, Result = 0; Index < NumberOfArgs; Index++) {
+//      //
+//      // The ... list is a series of UINTN values, so sum them up.
+//      //
+//      Result += VA_ARG (Marker, UINTN);
+//    }
+//
+//    VA_END (Marker);
+//    return Result;
+//  }
+//
+//  Notes:
+//  - Functions that call VA_START() / VA_END() must have a variable
+//    argument list and must be declared EFIAPI.
+//  - Functions that call VA_COPY() / VA_END() must be declared EFIAPI.
+//  - Functions that only use VA_LIST and VA_ARG() need not be EFIAPI.

+; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
+; For example, to define a structure called mytype containing a longword,
+; a word, a byte and a string of bytes, you might code
+;
+; struc   mytype
+;
+;  mt_long:      resd    1
+;  mt_word:      resw    1
+;  mt_byte:      resb    1
+;  mt_str:       resb    32
+;
+; endstruc
+;
+; Below macros are help to map the C types and the RESB family of pseudo-instructions.
+; So that the above structure definition can be coded as
+;
+; struc   mytype
+;
+;  mt_long:      CTYPE_UINT32    1
+;  mt_word:      CTYPE_UINT16    1

+                             function.
+

+                             Entry is set on output to the new collection entry
+                             that now links UserStruct.
+
+                             When insertion fails due to lack of memory
+                             (RETURN_OUT_OF_RESOURCES), Entry is not changed.
+
+                             When insertion fails due to key collision (ie.
+                             another user structure is already in the

+                             with later removal of the colliding element.
+
+  @param[in]     UserStruct  The user structure to link into the collection.
+                             UserStruct is ordered against in-collection user

+                                   has been allocated, linking UserStruct. The
+                                   new collection entry is reported back in
+                                   Entry (if the caller requested it).

+                                   into Collection remain valid. For example,

+                                   structure order dictates it.
+
+  @retval RETURN_OUT_OF_RESOURCES  The function failed to allocate memory for
+                                   the new collection entry. The collection has
+                                   not been changed. Existing

+/** @file
+  Provides library services to get and set Platform Configuration Database entries.
+
+  PCD Library Class provides a PCD usage macro interface for all PCD types.
+  It should be included in any module that uses PCD. If a module uses dynamic/dynamicex
+  PCD, module should be linked to a PEIM/DXE library instance to access that PCD.
+  If a module uses PatchableInModule type PCD, it also needs the library instance to produce
+  LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, the macro interface is
+  translated to a variable or macro that is auto-generated by build tool in
+  module's autogen.h/autogen.c.
+  The PcdGetXX(), PcdSetXX(), PcdToken(), and PcdGetNextTokenSpace() operations are
+  only available prior to ExitBootServices().  If access to PCD values are required
+  at runtime, then their values must be collected prior to ExitBootServices().
+  There are no restrictions on the use of FeaturePcd(), FixedPcdGetXX(),
+  PatchPcdGetXX(), and PatchPcdSetXX().

+  These functions perform PCI configuration cycles using the default PCI configuration
+  access method. This may use I/O ports 0xCF8 and 0xCFC to perform PCI configuration accesses,
+  or it may use MMIO registers relative to the PcdPciExpressBaseAddress, or it may use some
+  alternate access method.  Modules will typically use the PCI Library for its PCI configuration
+  accesses.  However, if a module requires a mix of PCI access methods, the PCI CF8 Library or
+  PCI Express Library may be used in conjunction with the PCI Library.  The functionality of
+  these three libraries is identical.  The PCI CF8 Library and PCI Express Library simply use
+  explicit access methods.

+/** @file
+  Provides services to access PCI Configuration Space on a platform with multiple PCI segments.
+
+  The PCI Segment Library function provide services to read, write, and modify the PCI configuration
+  registers on PCI root bridges on any supported PCI segment.  These library services take a single
+  address parameter that encodes the PCI Segment, PCI Bus, PCI Device, PCI Function, and PCI Register.
+  The layout of this address parameter is as follows:
+
+            PCI Register: Bits 0..11
+            PCI Function  Bits 12..14
+            PCI Device  Bits 15..19
+            PCI Bus Bits 20..27
+            Reserved  Bits 28..31.  Must be 0.
+            PCI Segment Bits 32..47
+            Reserved  Bits 48..63.  Must be 0.
+
+  | Reserved (MBZ) | Segment | Reserved (MBZ) |     Bus     | Device | Function | Register |
+  63             48  47    32  31           28 27         20 19    15 14      12 11         0
+
+  These functions perform PCI configuration cycles using the default PCI configuration access
+  method.  This may use I/O ports 0xCF8 and 0xCFC to perform PCI configuration accesses, or it
+  may use MMIO registers relative to the PcdPciExpressBaseAddress, or it may use some alternate
+  access method.  Modules will typically use the PCI Segment Library for its PCI configuration
+  accesses when PCI Segments other than Segment #0 must be accessed.

+  The Print Library functions provide a simple means to produce formatted output
+  strings.  Many of the output functions use a format string to describe how to
+  format the output of variable arguments.  The format string consists of normal

+  text and argument descriptors can be mixed.  The following end of line(EOL)
+  translations must be performed on the contents of the format string:
+
+     - '\\r' is translated to '\\r'
+     - '\\r\\n' is translated to '\\r\\n'
+     - '\\n' is translated to '\\r\\n'
+     - '\\n\\r' is translated to '\\r\\n'
+
+  This does not follow the ANSI C standard for sprint().  The format of argument
+  descriptors is described below.  The ANSI C standard for sprint() has been
+  followed for some of the format types, and has not been followed for others.
+  The exceptions are noted below.

+      - Prefix a space character to a number.  Only valid for types X, x, and d.
+    - +
+      - Prefix a plus character to a number.  Only valid for types X, x, and d.
+        If both space and + are specified, then space is ignored.

+      - Pad with 0 characters to the left of a number.  Only valid for types
+        X, x, and d.
+    - ,
+      - Place a comma every 3rd digit of the number.  Only valid for type d.
+        If 0 is also specified, then 0 is ignored.
+    - L, l
+      - The number being printed is size UINT64.  Only valid for types X, x, and d.
+        If this flag is not specified, then the number being printed is size int.
+    - NOTE: All invalid flags are ignored.
+
+  [width]:
+
+    - *
+      - The width of the field is specified by a UINTN argument in the
+        argument list.
+    - number
+      - The number specified as a decimal value represents the width of
+        the field.
+    - NOTE: If [width] is not specified, then a field width of 0 is assumed.
+
+  [.precision]:
+

+    - %
+      - Print a %%.
+    - c
+      - The argument is a Unicode character.  ASCII characters can be printed
+        using this type too by making sure bits 8..15 of the argument are set to 0.
+    - x
+      - The argument is an unsigned hexadecimal number.  The characters used are 0..9 and
+        A..F.  If the flag 'L' is not specified, then the argument is assumed
+        to be size int.  This does not follow ANSI C.

+  Provides library functions for common UEFI operations. Only available to DXE
+  and UEFI module types.
+
+  The UEFI Library provides functions and macros that simplify the development of
+  UEFI Drivers and UEFI Applications.  These functions and macros help manage EFI
+  events, build simple locks utilizing EFI Task Priority Levels (TPLs), install
+  EFI Driver Model related protocols, manage Unicode string tables for UEFI Drivers,
+  and print messages on the console output and standard error devices.
+
+  Note that a reserved macro named MDEPKG_NDEBUG is introduced for the intention
+  of size reduction when compiler optimization is disabled. If MDEPKG_NDEBUG is
+  defined, then debug and assert related macros wrapped by it are the NULL implementations.

+  The library constructor must set gRT to point at the EFI Runtime Services Table so

+  Runtime Services Table should use this library.
+  Only available to DXE and UEFI module types.

+  The entry point of PEI Foundation.
+
+  This function is the entry point for the PEI Foundation, which
+  allows the SEC phase to pass information about the stack,
+  temporary RAM and the Boot Firmware Volume. In addition, it also
+  allows the SEC phase to pass services and data forward for use
+  during the PEI phase in the form of one or more PPIs. These PPI's
+  will be installed and/or immediately signaled if they are
+  notification type. There is no limit to the number of additional
+  PPIs that can be passed from SEC into the PEI Foundation. As part
+  of its initialization phase, the PEI Foundation will add these
+  SEC-hosted PPIs to its PPI database such that both the PEI
+  Foundation and any modules can leverage the associated service
+  calls and/or code in these early PPIs.
+
+  @param SecCoreData    Points to a data structure containing
+                        information about the PEI core's
+                        operating environment, such as the size
+                        and location of temporary RAM, the stack
+                        location and the BFV location.
+
+  @param PpiList        Points to a list of one or more PPI
+                        descriptors to be installed initially by
+                        the PEI core. An empty PPI list consists
+                        of a single descriptor with the end-tag
+                        EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST.
+                        As part of its initialization phase, the

+  There is currently no way for the MM IPL driver to know that it must use two different addresses
+  depending on what it is trying to do. As a result, initial configuration and loading can use the
+  physical address PhysicalStart while MMRAM is open. However, once the region has been
+  closed and needs to be accessed by agents in MM, the CpuStart address must be used.
+  This PPI publishes the available memory that the chipset can shroud for the use of installing code.
+  These regions serve the dual purpose of describing which regions have been open, closed, or locked.
+  In addition, these regions may include overlapping memory ranges, depending on the chipset
+  implementation. The latter might include a chipset that supports T-SEG, where memory near the top
+  of the physical DRAM can be allocated for MMRAM too.
+  The key thing to note is that the regions that are described by the PPI are a subset of the capabilities
+  of the hardware.

+
+  For each item (token), the database can hold a single value that applies to all SKUs,
+  or multiple values, where each value is associated with a specific SKU Id. Items with multiple,

+  PI PCD ppi only provide the accessing interfaces for Dynamic-Ex type PCD.
+
+  This is the base PCD service API that provides an abstraction for accessing configuration content in

+  information is stored (such as in Read-only data, or an EFI Variable).
+  This protocol allows access to data through size-granular APIs and provides a mechanism for a
+  firmware component to monitor specific settings and be alerted when a setting is changed.

+
+  The S3RestoreConfig() function then executes the pre-stored boot script table

+/**
+  Set the configuration of the underlying inline cryptographic interface.
+
+  The SetConfiguration() function allows the user to set the current configuration of the
+  inline cryptographic interface and should be called before attempting any crypto operations.
+
+  This configures the configuration table entries with algorithms, key sizes and keys. Each
+  configured entry can later be referred to by index at the time of storage transaction.
+
+  The configuration table index will refer to the combination ofKeyOwnerGuid, Algorithm, and
+  CryptoKey.
+
+  KeyOwnerGuid identifies the component taking ownership of the entry. It helps components to
+  identify their own entries, cooperate with other owner components, and avoid conflicts. This
+  Guid identifier is there to help coordination between cooperating components and not a security
+  or synchronization feature. The Nil GUID can be used by a component to release use of entry
+  owned. It is also used to identify potentially available entries (see GetConfiguration).
+
+  CryptoKey specifies algorithm-specific key material to use within parameters of selected crypto
+  capability.
+
+  This function is called infrequently typically once, on device start, before IO starts. It
+  can be called at later times in cases the number of keysused on the drive is higher than what
+  can be configured at a time or a new key has to be added.
+
+  Components setting or changing an entry or entries for a given index or indices must ensure
+  that IO referencing affected indices is temporarily blocked (run-down) at the time of change.
+
+  Indices parameters in each parameter table entry allow to set only a portion of the available
+  table entries in the crypto module anywhere from single entry to entire table supported.
+
+  If corresponding table entry or entries being set are already in use by another owner the call
+  should be failed and none of the entries should be modified. The interface implementation must
+  enforce atomicity of this operation (should either succeed fully or fail completely without
+  modifying state).
+
+  Note that components using GetConfiguration command to discover available entries should be
+  prepared that by the time of calling SetConfiguration the previously available entry may have
+  become occupied. Such components should be prepared to re-try the sequence of operations.
+
+  Alternatively EFI_BLOCK_IO_CRYPTO_INDEX_ANY can be used to have the implementation discover
+  and allocate available,if any, indices atomically.
+
+  An optional ResultingTable pointer can be provided by the caller to receive the newly configured
+  entries. The array provided by the caller must have at least ConfigurationCount of entries.
+
+  @param[in]  This                Pointer to the EFI_BLOCK_IO_CRYPTO_PROTOCOL instance.
+  @param[in]  ConfigurationCount  Number of entries being configured with this call.

+                                state transition.
+  @param  Packet                The DHCP packet that is going to be sent or already received.

+                                driver to stop collecting additional packets. The driver will exit

+  The Firmware Volume Protocol provides file-level access to the firmware volume.
+  Each firmware volume driver must produce an instance of the
+  Firmware Volume Protocol if the firmware volume is to be visible to
+  the system during the DXE phase. The Firmware Volume Protocol also provides

+  Locates the requested section within a file and returns it in a buffer.
+
+  WriteFile() is used to write one or more files to a firmware
+  volume. Each file to be written is described by an
+  EFI_FV_WRITE_FILE_DATA structure. The caller must ensure that
+  any required alignment for all files listed in the FileData
+  array is compatible with the firmware volume. Firmware volume
+  capabilities can be determined using the GetVolumeAttributes()
+  call. Similarly, if the WritePolicy is set to
+  EFI_FV_RELIABLE_WRITE, the caller must check the firmware volume
+  capabilities to ensure EFI_FV_RELIABLE_WRITE is supported by the
+  firmware volume. EFI_FV_UNRELIABLE_WRITE must always be
+  supported. Writing a file with a size of zero
+  (FileData[n].BufferSize == 0) deletes the file from the firmware
+  volume if it exists. Deleting a file must be done one at a time.
+  Deleting a file as part of a multiple file write is not allowed.

+  Retrieves information about the next file in the firmware volume store

+
+  GetNextFile() is the interface that is used to search a firmware
+  volume for a particular file. It is called successively until
+  the desired file is located or the function returns
+   EFI_NOT_FOUND. To filter uninteresting files from the output,
+  the type of file to search for may be specified in FileType. For
+  example, if *FileType is EFI_FV_FILETYPE_DRIVER, only files of
+  this type will be returned in the output. If *FileType is
+  EFI_FV_FILETYPE_ALL, no filtering of file types is done. The Key
+  parameter is used to indicate a starting point of the search. If
+  the buffer *Key is completely initialized to zero, the search
+  re-initialized and starts at the beginning. Subsequent calls to
+  GetNextFile() must maintain the value of *Key returned by the
+  immediately previous call. The actual contents of *Key are
+  implementation specific and no semantic content is implied.
+  GetNextFile() is callable only from TPL_NOTIFY and below.
+  Behavior of GetNextFile() at any EFI_TPL above TPL_NOTIFY is

+  @param Key        Pointer to a caller-allocated buffer that contains implementation-specific data that is

+                    at least This->KeySize bytes long. To re-initialize the search and begin from the
+                    beginning of the firmware volume, the entire buffer must be cleared to zero. Other
+                    than clearing the buffer to initiate a new search, the caller must not modify the data in
+                    the buffer between calls to GetNextFile().
+
+  @param FileType   Pointer to a caller-allocated
+                    EFI_FV_FILETYPE. The GetNextFile() API can
+                    filter its search for files based on the
+                    value of the FileType input. A *FileType
+                    input of EFI_FV_FILETYPE_ALL causes
+                    GetNextFile() to search for files of all
+                    types. If a file is found, the file's type

+                    EFI_FV_FILE_ATTRIBUTES. If a matching file
+                    is found, the file's attributes are returned
+                    in Attributes. If no matching file is found,

+  Erases and initializes a firmware volume block.
+
+  The EraseBlocks() function erases one or more blocks as denoted

+  requested that does not exist within the associated firmware
+  volume (it has a larger index than the last block of the
+  firmware volume), the EraseBlocks() function must return the

+
+                The list is terminated with an
+                EFI_LBA_LIST_TERMINATOR. For example, the

+  They must have an additional description indicating the type of
+  alternative configuration the string represents,
+  "ALTCFG=<StringToken>". That <StringToken> (when
+  converted from Hex UNICODE to binary) is a reference to a
+  string in the associated string pack.
+
+  @param This       Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.

+  This function allows the caller to request the current
+  configuration for one or more named elements from one or more
+  drivers. The resulting string is in the standard HII
+  configuration string format. If Successful, Results contains an
+  equivalent string with "=" and the values associated with all
+  names added in. The expected implementation is for each
+  <ConfigRequest> substring in the Request to call the HII
+  Configuration Routing Protocol ExtractProtocol function for the
+  driver corresponding to the <ConfigHdr> at the start of the
+  <ConfigRequest> substring. The request fails if no driver
+  matches the <ConfigRequest> substring. Note: Alternative
+  configuration strings may also be appended to the end of the
+  current configuration string. If they are, they must appear
+  after the current configuration. They must contain the same
+  routing (GUID, NAME, PATH) as the current configuration string.
+  They must have an additional description indicating the type of
+  alternative configuration the string represents,
+  "ALTCFG=<StringToken>". That <StringToken> (when converted from
+  hexadecimal (encoded as text) to binary) is a reference to a string in the
+  associated string pack. As an example, assume that the Request
+  string is:
+  GUID=...&NAME=00480050&PATH=...&Fred&George&Ron&Neville A result

+  This function renders a string to a bitmap or the screen using
+  the specified font, color and options. It either draws the
+  string and glyphs on an existing bitmap, allocates a new bitmap,
+  or uses the screen. The strings can be clipped or wrapped.
+  Optionally, the function also returns the information about each
+  row and the character position on that row. If
+  EFI_HII_OUT_FLAG_CLIP is set, then text will be formatted only
+  based on explicit line breaks and all pixels which would lie
+  outside the bounding box specified by Width and Height are
+  ignored. The information in the RowInfoArray only describes
+  characters which are at least partially displayed. For the final
+  row, the LineHeight and BaseLine may describe pixels that are
+  outside the limit specified by Height (unless
+  EFI_HII_OUT_FLAG_CLIP_CLEAN_Y is specified) even though those
+  pixels were not drawn. The LineWidth may describe pixels which
+  are outside the limit specified by Width (unless
+  EFI_HII_OUT_FLAG_CLIP_CLEAN_X is specified) even though those
+  pixels were not drawn. If EFI_HII_OUT_FLAG_CLIP_CLEAN_X is set,
+  then it modifies the behavior of EFI_HII_OUT_FLAG_CLIP so that
+  if a character's right-most on pixel cannot fit, then it will
+  not be drawn at all. This flag requires that
+  EFI_HII_OUT_FLAG_CLIP be set. If EFI_HII_OUT_FLAG_CLIP_CLEAN_Y
+  is set, then it modifies the behavior of EFI_HII_OUT_FLAG_CLIP
+  so that if a row's bottom-most pixel cannot fit, then it will
+  not be drawn at all. This flag requires that
+  EFI_HII_OUT_FLAG_CLIP be set. If EFI_HII_OUT_FLAG_WRAP is set,
+  then text will be wrapped at the right-most line-break
+  opportunity prior to a character whose right-most extent would
+  exceed Width. If no line-break opportunity can be found, then
+  the text will behave as if EFI_HII_OUT_FLAG_CLIP_CLEAN_X is set.
+  This flag cannot be used with EFI_HII_OUT_FLAG_CLIP_CLEAN_X. If
+  EFI_HII_OUT_FLAG_TRANSPARENT is set, then BackgroundColor is
+  ignored and all 'off' pixels in the character's drawn
+  will use the pixel value from Blt. This flag cannot be used if
+  Blt is NULL upon entry. If EFI_HII_IGNORE_IF_NO_GLYPH is set,
+  then characters which have no glyphs are not drawn. Otherwise,
+  they are replaced with Unicode character code 0xFFFD (REPLACEMENT
+  CHARACTER). If EFI_HII_IGNORE_LINE_BREAK is set, then explicit
+  line break characters will be ignored. If
+  EFI_HII_DIRECT_TO_SCREEN is set, then the string will be written
+  directly to the output device specified by Screen. Otherwise the
+  string will be rendered to the bitmap specified by Bitmap.

+
+  @param Blt              If this points to a non-NULL on entry, this points

+                          where it is displayed. Non-printing
+                          characters will have the offset ~0.
+                          The caller is responsible to allocate
+                          a buffer large enough so that there is
+                          one entry for each character in the

+  opaque. If EFI_HII_DRAW_FLAG_FORCE_TRANS is set, then the image
+  will be drawn so that all 'off' pixels in the image will
+  be drawn using the pixel value from Blt and all other pixels
+  will be copied. If EFI_HII_DRAW_FLAG_FORCE_OPAQUE is set, then
+  the image's pixels will be copied directly to the
+  destination. If EFI_HII_DRAW_FLAG_DEFAULT is set, then the image
+  will be drawn transparently or opaque, depending on the
+  image's transparency setting (see EFI_IMAGE_TRANSPARENT).
+  Images cannot be drawn transparently if Blt is NULL. If
+  EFI_HII_DIRECT_TO_SCREEN is set, then the image will be written
+  directly to the output device specified by Screen. Otherwise the
+  image will be rendered to the bitmap specified by Bitmap.

+                      will be allocated to hold the generated image and

+                      responsibility to free this buffer.
+

+  The Response() function queues an HTTP response to this HTTP instance, similar to

+
+  The HTTP driver will queue a receive token to the underlying TCP instance. When data
+  is received in the underlying TCP instance, the data will be parsed and Token will
+  be populated with the response data. If the data received from the remote host
+  contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+  (asynchronously) for more data to be sent from the remote host before signaling
+  Event in Token.
+
+  It is the responsibility of the caller to allocate a buffer for Body and specify the
+  size in BodyLength. If the remote host provides a response that contains a content
+  body, up to BodyLength bytes will be copied from the receive buffer into Body and
+  BodyLength will be updated with the amount of bytes received and copied to Body. This
+  allows the client to download a large file in chunks instead of into one contiguous
+  block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is

+///
+/// The I2C protocol stack uses the concept of an I2C bus configuration as
+/// a way to describe a particular state of the switches and multiplexers
+/// in the I2C bus.
+///
+/// A simple I2C bus does not have any multiplexers or switches is described
+/// to the I2C protocol stack with a single I2C bus configuration which
+/// specifies the I2C bus frequency.
+///
+/// An I2C bus with switches and multiplexers use an I2C bus configuration
+/// to describe each of the unique settings for the switches and multiplexers
+/// and the I2C bus frequency.  However the I2C bus configuration management
+/// protocol only needs to define the I2C bus configurations that the software
+/// uses, which may be a subset of the total.
+///
+/// The I2C bus configuration description includes a list of I2C devices
+/// which may be accessed when this I2C bus configuration is enabled.  I2C
+/// devices before a switch or multiplexer must be included in one I2C bus
+/// configuration while I2C devices after a switch or multiplexer are on
+/// another I2C bus configuration.
+///
+/// The I2C bus configuration management protocol is an optional protocol.
+/// When the I2C bus configuration protocol is not defined the I2C host
+/// protocol does not start and the I2C master protocol may be used for
+/// other purposes such as SMBus traffic.  When the I2C bus configuration
+/// protocol is available, the I2C host protocol uses the I2C bus
+/// configuration protocol to call into the platform specific code to set
+/// the switches and multiplexers and set the maximum I2C bus frequency.
+///
+/// The platform designers determine the maximum I2C bus frequency by
+/// selecting a frequency which supports all of the I2C devices on the
+/// I2C bus for the setting of switches and multiplexers.  The platform
+/// designers must validate this against the I2C device data sheets and
+/// any limits of the I2C controller or bus length.
+///
+/// During I2C device enumeration, the I2C bus driver retrieves the I2C
+/// bus configuration that must be used to perform I2C transactions to
+/// each I2C device.  This I2C bus configuration value is passed into
+/// the I2C host protocol to identify the I2C bus configuration required
+/// to access a specific I2C device.  The I2C host protocol calls
+/// EnableBusConfiguration() to set the switches and multiplexers in the
+/// I2C bus and the I2C clock frequency.  The I2C host protocol may
+/// optimize calls to EnableBusConfiguration() by only making the call
+/// when the I2C bus configuration value changes between I2C requests.
+///
+/// When I2C transactions are required on the same I2C bus to change the
+/// state of multiplexers or switches, the I2C master protocol must be
+/// used to perform the necessary I2C transactions.
+///
+/// It is up to the platform specific code to choose the proper I2C bus
+/// configuration when ExitBootServices() is called. Some operating systems
+/// are not able to manage the I2C bus configurations and must use the I2C
+/// bus configuration that is established by the platform firmware before
+/// ExitBootServices() returns.

+
+  This routine must be called at or below TPL_NOTIFY.  For
+  synchronous requests this routine must be called at or below
+  TPL_CALLBACK.
+
+  The I2C host protocol uses the concept of I2C bus configurations
+  to describe the I2C bus.  An I2C bus configuration is defined as
+  a unique setting of the multiplexers and switches in the I2C bus
+  which enable access to one or more I2C devices.  When using a
+  switch to divide a bus, due to bus frequency differences, the
+  I2C bus configuration management protocol defines an I2C bus
+  configuration for the I2C devices on each side of the switch.
+  When using a multiplexer, the I2C bus configuration management
+  defines an I2C bus configuration for each of the selector values
+  required to control the multiplexer.  See Figure 1 in the I2C -bus
+  specification and user manual for a complex I2C bus configuration.
+
+  The I2C host protocol processes all transactions in FIFO order.
+  Prior to performing the transaction, the I2C host protocol calls
+  EnableI2cBusConfiguration to reconfigure the switches and
+  multiplexers in the I2C bus enabling access to the specified I2C
+  device.  The EnableI2cBusConfiguration also selects the I2C bus
+  frequency for the I2C device.  After the I2C bus is configured,
+  the I2C host protocol calls the I2C master protocol to start the
+  I2C transaction.
+
+  When Event is NULL, QueueRequest() operates synchronously and
+  returns the I2C completion status as its return value.
+
+  When Event is not NULL, QueueRequest() synchronously returns
+  EFI_SUCCESS indicating that the asynchronously I2C transaction was

+  Start an I2C transaction on the host controller.
+
+  This routine must be called at or below TPL_NOTIFY.  For synchronous
+  requests this routine must be called at or below TPL_CALLBACK.
+
+  This function initiates an I2C transaction on the controller.  To
+  enable proper error handling by the I2C protocol stack, the I2C
+  master protocol does not support queuing but instead only manages
+  one I2C transaction at a time.  This API requires that the I2C bus
+  is in the correct configuration for the I2C transaction.
+
+  The transaction is performed by sending a start-bit and selecting the
+  I2C device with the specified I2C slave address and then performing
+  the specified I2C operations.  When multiple operations are requested
+  they are separated with a repeated start bit and the slave address.
+  The transaction is terminated with a stop bit.
+
+  When Event is NULL, StartRequest operates synchronously and returns
+  the I2C completion status as its return value.
+
+  When Event is not NULL, StartRequest synchronously returns EFI_SUCCESS
+  indicating that the I2C transaction was started asynchronously.  The
+  transaction status value is returned in the buffer pointed to by
+  I2cStatus upon the completion of the I2C transaction when I2cStatus
+  is not NULL.  After the transaction status is returned the Event is
+  signaled.
+
+  Note: The typical consumer of this API is the I2C host protocol.
+  Extreme care must be taken by other consumers of this API to prevent
+  confusing the third party I2C drivers due to a state change at the
+  I2C device which the third party I2C drivers did not initiate.  I2C
+  platform specific code may use this API within these guidelines.

+                            clear this bit for 7-bit addressing.  Bits 0-6
+                            are used for 7-bit I2C slave addresses and bits
+                            0-9 are used for 10-bit I2C slave addresses.

+/** @file
+  This file declares Incompatible PCI Device Support Protocol
+
+  Allows the PCI bus driver to support resource allocation for some PCI devices
+  that do not comply with the PCI Specification.
+
+  @par Note:
+    This protocol is optional. Only those platforms that implement this protocol
+    will have the capability to support incompatible PCI devices. The absence of
+    this protocol can cause the PCI bus driver to configure these incompatible
+    PCI devices incorrectly. As a result, these devices may not work properly.
+
+  The EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL is used by the PCI bus driver
+  to support resource allocation for some PCI devices that do not comply with the
+  PCI Specification.  This protocol can find some incompatible PCI devices and
+  report their special resource requirements to the PCI bus driver. The generic
+  PCI bus driver does not have prior knowledge of any incompatible PCI devices.
+  It interfaces with the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL to find out
+  if a device is incompatible and to obtain the special configuration requirements
+  for a specific incompatible PCI device.
+
+  This protocol is optional, and only one instance of this protocol can be present
+  in the system. If a platform supports this protocol, this protocol is produced
+  by a Driver Execution Environment (DXE) driver and must be made available before
+  the Boot Device Selection (BDS) phase. The PCI bus driver will look for the
+  presence of this protocol before it begins PCI enumeration.  If this protocol
+  exists in a platform, it indicates that the platform has the capability to support
+  those incompatible PCI devices. However, final support for incompatible PCI
+  devices still depends on the implementation of the PCI bus driver. The PCI bus
+  driver may fully, partially, or not even support these incompatible devices.
+
+  During PCI bus enumeration, the PCI bus driver will probe the PCI Base Address
+  Registers (BARs) for each PCI device regardless of whether the PCI device is
+  incompatible or not to determine the resource requirements so that the PCI bus
+  driver can invoke the proper PCI resources for them.  Generally, this resource
+  information includes the following:
+    - Resource type
+    - Resource length
+    - Alignment
+
+  However, some incompatible PCI devices may have special requirements. As a result,
+  the length or the alignment that is derived through BAR probing may not be exactly
+  the same as the actual resource requirement of the device. For example, there
+  are some devices that request I/O resources at a length of 0x100 from their I/O
+  BAR, but these incompatible devices will never work correctly if an odd I/O base
+  address, such as 0x100, 0x300, or 0x500, is assigned to the BAR. Instead, these
+  devices request an even base address, such as 0x200 or 0x400. The Incompatible
+  PCI Device Support Protocol can then be used to obtain these special resource
+  requirements for these incompatible PCI devices. In this way, the PCI bus driver
+  will take special consideration for these devices during PCI resource allocation
+  to ensure that they can work correctly.
+
+  This protocol may support the following incompatible PCI BAR types:
+    - I/O or memory length that is different from what the BAR reports
+    - I/O or memory alignment that is different from what the BAR reports
+    - Fixed I/O or memory base address
+
+  See the Conventional PCI Specification 3.0 for the details of how a PCI BAR
+  reports the resource length and the alignment that it requires.

+  Returns a list of ACPI resource descriptors that detail the special resource
+  configuration requirements for an incompatible PCI device.
+
+  This function returns a list of ACPI resource descriptors that detail the
+  special resource configuration requirements for an incompatible PCI device.
+
+  Prior to bus enumeration, the PCI bus driver will look for the presence
+  of the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL. Only one instance of this
+  protocol can be present in the system. For each PCI device that the PCI bus
+  driver discovers, the PCI bus driver calls this function with the device's vendor
+  ID, device ID, revision ID, subsystem vendor ID, and subsystem device ID. If the
+  VendorId, DeviceId, RevisionId, SubsystemVendorId, or SubsystemDeviceId value is
+  set to (UINTN)-1, that field will be ignored. The ID values that are not (UINTN)-1
+  will be used to identify the current device.
+
+  This function will only return EFI_SUCCESS. However, if the device is an
+  incompatible PCI device, a list of ACPI resource descriptors will be returned
+  in Configuration. Otherwise, NULL will be returned in Configuration instead.
+  The PCI bus driver does not need to allocate memory for Configuration. However,
+  it is the PCI bus driver's responsibility to free it. The PCI bus driver then
+  can configure this device with the information that is derived from this list
+  of resource nodes, rather than the result of BAR probing.
+
+  Only the following two resource descriptor types from the ACPI Specification
+  may be used to describe the incompatible PCI device resource requirements:
+    - QWORD Address Space Descriptor (ACPI 2.0, section 6.4.3.5.1; also ACPI 3.0)
+    - End Tag (ACPI 2.0, section 6.4.2.8; also ACPI 3.0)
+
+  The QWORD Address Space Descriptor can describe memory, I/O, and bus number
+  ranges for dynamic or fixed resources.  The configuration of a PCI root bridge
+  is described with one or more QWORD Address Space Descriptors, followed by an
+  End Tag. See the ACPI Specification for details on the field values.

+  - EFI IPv4 Variable (deprecated in UEFI 2.4B)
+  - EFI IPv4 Protocol.
+  The EFI IPv4 Protocol provides basic network IPv4 packet I/O services,
+  which includes support foR a subset of the Internet Control Message
+  Protocol (ICMP) and may include support for the Internet Group Management
+  Protocol (IGMP).

+  Starts running the configuration policy for the EFI IPv4 Protocol driver.

+  The Start() function is called to determine and to begin the platform

+  driver configuration policy. It may be as involved as loading some defaults
+  from nonvolatile storage, downloading dynamic data from a DHCP server, and
+  checking permissions with a site policy server.
+  Starting the configuration policy is just the beginning. It may finish almost
+  instantly or it may take several minutes before it fails to retrieve configuration
+  information from one or more servers. Once the policy is started, drivers
+  should use the DoneEvent parameter to determine when the configuration policy
+  has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to
+  determine if the configuration succeeded or failed.
+  Until the configuration completes successfully, EFI IPv4 Protocol driver instances
+  that are attempting to use default configurations must return EFI_NO_MAPPING.
+  Once the configuration is complete, the EFI IPv4 Configuration Protocol driver
+  signals DoneEvent. The configuration may need to be updated in the future.
+  Note that in this case the EFI IPv4 Configuration Protocol driver must signal
+  ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default
+  configurations must return EFI_NO_MAPPING until the configuration policy has
+  been rerun.

+  Set the configuration for the EFI IPv4 network stack running on the communication device this EFI

+  running on the communication device this EFI IPv4 Configuration II Protocol instance manages.
+  The successfully configured data is valid after system reset or power-off.
+  The DataSize is used to calculate the count of structure instances in the Data for some
+  DataType that multiple structure instances are allowed.
+  This function is always non-blocking. When setting some typeof configuration data, an
+  asynchronous process is invoked to check the correctness of the data, such as doing address conflict
+  detection on the manually set local IPv4 address. EFI_NOT_READY is returned immediately to
+  indicate that such an asynchronous process is invoked and the process is not finished yet. The caller
+  willing to get the result of the asynchronous process is required to call RegisterDataNotify()
+  to register an event on the specified configuration data. Once the event is signaled, the caller can call
+  GetData()to get back the configuration data in order to know the result. For other types of
+  configuration data that do not require an asynchronous configuration process, the result of the

+                                        AP of the system. Type EFI_AP_PROCEDURE2 is defined below in
+                                        related definitions.
+  @param[in]     CpuNumber              The zero-based index of the processor number of the target
+                                        AP, on which the code stream is supposed to run. If the number
+                                        points to the calling processor then it will not run the
+                                        supplied code.
+  @param[in]     TimeoutInMicroseconds  Indicates the time limit in microseconds for this AP to
+                                        finish execution of Procedure, either for blocking or
+                                        non-blocking mode. Zero means infinity. If the timeout
+                                        expires before this AP returns from Procedure, then Procedure
+                                        on the AP is terminated. If the timeout expires in blocking
+                                        mode, the call returns EFI_TIMEOUT. If the timeout expires
+                                        in non-blocking mode, the timeout determined can be through
+                                        CheckOnProcedure or WaitForProcedure.
+                                        Note that timeout support is optional. Whether an
+                                        implementation supports this feature, can be determined via
+                                        the Attributes data member.
+  @param[in,out] ProcedureArguments     Allows the caller to pass a list of parameters to the code
+                                        that is run by the AP. It is an optional common mailbox
+                                        between APs and the caller to share information.

+                                        caller to execute the procedure in a blocking or non-blocking
+                                        fashion. If it is NULL the call is blocking, and the call will
+                                        not return until the AP has completed the procedure. If the

+                                        when it completes execution on the target AP, or with EFI_TIMEOUT
+                                        if the Procedure fails to complete within the optional timeout.
+                                        The implementation will update this variable with EFI_NOT_READY
+                                        prior to starting Procedure on the target AP.

+/** @file
+  When installed, the MP Services Protocol produces a collection of services
+  that are needed for MP management.
+
+  The MP Services Protocol provides a generalized way of performing following tasks:
+    - Retrieving information of multi-processor environment and MP-related status of
+      specific processors.
+    - Dispatching user-provided function to APs.
+    - Maintain MP-related processor status.
+
+  The MP Services Protocol must be produced on any system with more than one logical
+  processor.
+
+  The Protocol is available only during boot time.
+
+  MP Services Protocol is hardware-independent. Most of the logic of this protocol
+  is architecturally neutral. It abstracts the multi-processor environment and
+  status of processors, and provides interfaces to retrieve information, maintain,
+  and dispatch.
+
+  MP Services Protocol may be consumed by ACPI module. The ACPI module may use this
+  protocol to retrieve data that are needed for an MP platform and report them to OS.
+  MP Services Protocol may also be used to program and configure processors, such
+  as MTRR synchronization for memory space attributes setting in DXE Services.
+  MP Services Protocol may be used by non-CPU DXE drivers to speed up platform boot
+  by taking advantage of the processing capabilities of the APs, for example, using
+  APs to help test system memory in parallel with other device initialization.
+  Diagnostics applications may also use this protocol for multi-processor.

+  This service executes a caller provided function on all enabled APs. APs can
+  run either simultaneously or one at a time in sequence. This service supports
+  both blocking and non-blocking requests. The non-blocking requests use EFI
+  events so the BSP can detect when the APs have finished. This service may only
+  be called from the BSP.
+
+  This function is used to dispatch all the enabled APs to the function specified
+  by Procedure.  If any enabled AP is busy, then EFI_NOT_READY is returned
+  immediately and Procedure is not started on any AP.
+
+  If SingleThread is TRUE, all the enabled APs execute the function specified by
+  Procedure one by one, in ascending order of processor handle number. Otherwise,
+  all the enabled APs execute the function specified by Procedure simultaneously.
+
+  If WaitEvent is NULL, execution is in blocking mode. The BSP waits until all
+  APs finish or TimeoutInMicroSecs expires. Otherwise, execution is in non-blocking
+  mode, and the BSP returns from this service without waiting for APs. If a
+  non-blocking mode is requested after the UEFI Event EFI_EVENT_GROUP_READY_TO_BOOT
+  is signaled, then EFI_UNSUPPORTED must be returned.
+
+  If the timeout specified by TimeoutInMicroseconds expires before all APs return
+  from Procedure, then Procedure on the failed APs is terminated. All enabled APs
+  are always available for further calls to EFI_MP_SERVICES_PROTOCOL.StartupAllAPs()
+  and EFI_MP_SERVICES_PROTOCOL.StartupThisAP(). If FailedCpuList is not NULL, its
+  content points to the list of processor handle numbers in which Procedure was
+  terminated.
+
+  Note: It is the responsibility of the consumer of the EFI_MP_SERVICES_PROTOCOL.StartupAllAPs()
+  to make sure that the nature of the code that is executed on the BSP and the
+  dispatched APs is well controlled. The MP Services Protocol does not guarantee
+  that the Procedure function is MP-safe. Hence, the tasks that can be run in
+  parallel are limited to certain independent tasks and well-controlled exclusive
+  code. EFI services and protocols may not be called by APs unless otherwise
+  specified.
+
+  In blocking execution mode, BSP waits until all APs finish or
+  TimeoutInMicroSeconds expires.
+
+  In non-blocking execution mode, BSP is freed to return to the caller and then
+  proceed to the next task without having to wait for APs. The following
+  sequence needs to occur in a non-blocking execution mode:
+
+    -# The caller that intends to use this MP Services Protocol in non-blocking
+       mode creates WaitEvent by calling the EFI CreateEvent() service.  The caller
+       invokes EFI_MP_SERVICES_PROTOCOL.StartupAllAPs(). If the parameter WaitEvent
+       is not NULL, then StartupAllAPs() executes in non-blocking mode. It requests
+       the function specified by Procedure to be started on all the enabled APs,
+       and releases the BSP to continue with other tasks.
+    -# The caller can use the CheckEvent() and WaitForEvent() services to check
+       the state of the WaitEvent created in step 1.
+    -# When the APs complete their task or TimeoutInMicroSecondss expires, the MP
+       Service signals WaitEvent by calling the EFI SignalEvent() function. If
+       FailedCpuList is not NULL, its content is available when WaitEvent is
+       signaled. If all APs returned from Procedure prior to the timeout, then
+       FailedCpuList is set to NULL. If not all APs return from Procedure before
+       the timeout, then FailedCpuList is filled in with the list of the failed
+       APs. The buffer is allocated by MP Service Protocol using AllocatePool().
+       It is the caller's responsibility to free the buffer with FreePool() service.
+    -# This invocation of SignalEvent() function informs the caller that invoked
+       EFI_MP_SERVICES_PROTOCOL.StartupAllAPs() that either all the APs completed
+       the specified task or a timeout occurred. The contents of FailedCpuList
+       can be examined to determine which APs did not complete the specified task
+       prior to the timeout.

+                                      blocking mode. BSP waits until all APs finish
+                                      or TimeoutInMicroSeconds expires.  If it's
+                                      not NULL, then execute in non-blocking mode.
+                                      BSP requests the function specified by
+                                      Procedure to be started on all the enabled
+                                      APs, and go on executing immediately. If
+                                      all return from Procedure, or TimeoutInMicroSeconds
+                                      expires, this event is signaled. The BSP
+                                      can use the CheckEvent() or WaitForEvent()
+                                      services to check the state of event.  Type
+                                      EFI_EVENT is defined in CreateEvent() in
+                                      the Unified Extensible Firmware Interface
+                                      Specification.
+  @param[in]  TimeoutInMicrosecsond   Indicates the time limit in microseconds for
+                                      APs to return from Procedure, either for
+                                      blocking or non-blocking mode. Zero means
+                                      infinity.  If the timeout expires before
+                                      all APs return from Procedure, then Procedure
+                                      on the failed APs is terminated. All enabled
+                                      APs are available for next function assigned

+  See EFI_MP_SERVICES_PROTOCOL.StartupAllAPs() for more details on non-blocking
+  execution support.  This service may only be called from the BSP.
+
+  This function is used to dispatch one enabled AP to the function specified by
+  Procedure passing in the argument specified by ProcedureArgument.  If WaitEvent
+  is NULL, execution is in blocking mode. The BSP waits until the AP finishes or
+  TimeoutInMicroSecondss expires. Otherwise, execution is in non-blocking mode.
+  BSP proceeds to the next task without waiting for the AP. If a non-blocking mode
+  is requested after the UEFI Event EFI_EVENT_GROUP_READY_TO_BOOT is signaled,
+  then EFI_UNSUPPORTED must be returned.
+
+  If the timeout specified by TimeoutInMicroseconds expires before the AP returns
+  from Procedure, then execution of Procedure by the AP is terminated. The AP is
+  available for subsequent calls to EFI_MP_SERVICES_PROTOCOL.StartupAllAPs() and

+                                      not NULL, then execute in non-blocking mode.
+                                      BSP requests the function specified by

+                                      and go on executing immediately. If this AP

+                                      this AP returns from Procedure, then Procedure
+                                      on the AP is terminated. The

+/** @file
+  This file declares EFI PCI Hot Plug Init Protocol.
+
+  This protocol provides the necessary functionality to initialize the Hot Plug
+  Controllers (HPCs) and the buses that they control. This protocol also provides
+  information regarding resource padding.
+
+  @par Note:
+    This protocol is required only on platforms that support one or more PCI Hot
+    Plug* slots or CardBus sockets.
+
+  The EFI_PCI_HOT_PLUG_INIT_PROTOCOL provides a mechanism for the PCI bus enumerator
+  to properly initialize the HPCs and CardBus sockets that require initialization.
+  The HPC initialization takes place before the PCI enumeration process is complete.
+  There cannot be more than one instance of this protocol in a system. This protocol
+  is installed on its own separate handle.
+
+  Because the system may include multiple HPCs, one instance of this protocol
+  should represent all of them. The protocol functions use the device path of
+  the HPC to identify the HPC. When the PCI bus enumerator finds a root HPC, it
+  will call EFI_PCI_HOT_PLUG_INIT_PROTOCOL.InitializeRootHpc(). If InitializeRootHpc()
+  is unable to initialize a root HPC, the PCI enumerator will ignore that root HPC
+  and continue the enumeration process. If the HPC is not initialized, the devices
+  that it controls may not be initialized, and no resource padding will be provided.
+
+  From the standpoint of the PCI bus enumerator, HPCs are divided into the following
+  two classes:
+
+    - Root HPC:
+        These HPCs must be initialized by calling InitializeRootHpc() during the
+        enumeration process. These HPCs will also require resource padding. The
+        platform code must have a priori knowledge of these devices and must know
+        how to initialize them. There may not be any way to access their PCI
+        configuration space before the PCI enumerator programs all the upstream
+        bridges and thus enables the path to these devices. The PCI bus enumerator
+        is responsible for determining the PCI bus address of the HPC before it
+        calls InitializeRootHpc().
+    - Nonroot HPC:
+        These HPCs will not need explicit initialization during enumeration process.
+        These HPCs will require resource padding. The platform code does not have
+        to have a priori knowledge of these devices.

+  Provides services to notify the PCI bus driver that some events have happened

+  PCI bus driver to create or destroy handles for PCI-like devices.
+
+  A hot-plug capable PCI bus driver should produce the EFI PCI Hot Plug Request
+  protocol. When a PCI device or a PCI-like device (for example, 32-bit PC Card)
+  is installed after PCI bus does the enumeration, the PCI bus driver can be
+  notified through this protocol. For example, when a 32-bit PC Card is inserted
+  into the PC Card socket, the PC Card bus driver can call interface of this
+  protocol to notify PCI bus driver to allocate resource and create handles for
+  this PC Card.
+
+  The EFI_PCI_HOTPLUG_REQUEST_PROTOCOL is installed by the PCI bus driver on a
+  separate handle when PCI bus driver starts up. There is only one instance in
+  the system.  Any driver that wants to use this protocol must locate it globally.
+  The EFI_PCI_HOTPLUG_REQUEST_PROTOCOL allows the driver of hot-plug controller,
+  for example, PC Card Bus driver, to notify PCI bus driver that an event has
+  happened in the hot-plug controller, and the PCI bus driver is requested to
+  create (add) or destroy (remove) handles for the specified PCI-like devices.
+  For example, when a 32-bit PC Card is inserted, this protocol interface will
+  be called with an add operation, and the PCI bus driver will enumerate and
+  start the devices inserted; when a 32-bit PC Card is removed, this protocol
+  interface will be called with a remove operation, and the PCI bus driver will
+  stop the devices and destroy their handles.  The existence of this protocol
+  represents the capability of the PCI bus driver. If this protocol exists in
+  system, it means PCI bus driver is hot-plug capable, thus together with the
+  effort of PC Card bus driver, hot-plug of PC Card can be supported. Otherwise,
+  the hot-plug capability is not provided.

+  the PCI bus driver will enumerate, allocate resources for devices behind the
+  hot-plug controller, and create handle for the device specified by RemainingDevicePath.
+  The RemainingDevicePath is an optional parameter. If it is not NULL, only the
+  specified device is started; if it is NULL, all devices behind the hot-plug
+  controller are started.  The newly created handles of PC Card functions are
+  returned in the ChildHandleBuffer, together with the number of child handle in
+  NumberOfChildren.  If it is a remove operation, when NumberOfChildren contains
+  a non-zero value, child handles specified in ChildHandleBuffer are stopped and
+  destroyed; otherwise, PCI bus driver is notified to stop managing the controller
+  handle.
+
+    @param[in] This                    A pointer to the EFI_PCI_HOTPLUG_REQUEST_PROTOCOL
+                                       instance.
+    @param[in] Operation               The operation the PCI bus driver is requested
+                                       to make.
+    @param[in] Controller              The handle of the hot-plug controller.
+    @param[in] RemainingDevicePath     The remaining device path for the PCI-like
+                                       hot-plug device.  It only contains device
+                                       path nodes behind the hot-plug controller.
+                                       It is an optional parameter and only valid
+                                       when the Operation is a add operation. If
+                                       it is NULL, all devices behind the PC Card
+                                       socket are started.
+    @param[in,out] NumberOfChildren    The number of child handles. For an add
+                                       operation, it is an output parameter.  For
+                                       a remove operation, it's an input parameter.
+                                       When it contains a non-zero value, children
+                                       handles specified in ChildHandleBuffer are
+                                       destroyed.  Otherwise, PCI bus driver is
+                                       notified to stop managing the controller
+                                       handle.
+    @param[in,out] ChildHandleBuffer   The buffer which contains the child handles.
+                                       For an add operation, it is an output
+                                       parameter and contains all newly created
+                                       child handles.  For a remove operation, it
+                                       contains child handles to be destroyed when
+                                       NumberOfChildren contains a non-zero value.
+                                       It can be NULL when NumberOfChildren is 0.
+                                       It's the caller's responsibility to allocate
+                                       and free memory for this buffer.
+
+  @retval EFI_SUCCESS             The handles for the specified device have been
+                                  created or destroyed as requested, and for an

+///       ranges. In this scheme, seventy-five percent of the I/O space remains unused.
+///       By using this selection, the platform indicates that it wants to support

+///       ISA range and its aliases
+///       Legacy VGA range and its aliases
+///       The PCI bus driver will not allocate I/O addresses out of the ISA I/O
+///       range and its aliases. The following are the ISA I/O ranges:

+///         - n500..n7FF
+///         - n900..nBFF
+///         - nD00..nFFF

+///       In this case, the PCI bus driver will ask the PCI host bridge driver for
+///       larger I/O ranges. The PCI host bridge driver is not aware of the ISA
+///       aliasing policy and merely attempts to allocate the requested ranges.
+///       The first device that requests the legacy VGA range will get all the

+///       ranges, including those that require VGA aliases. The platform further
+///       wants to support non-VGA devices that ask for the ISA range (0x100 -
+///       3FF), but not if it also asks for the ISA aliases. The PCI bus driver will
+///       not allocate I/O addresses out of the legacy ISA I/O range (0x100 -

+///       require VGA aliases. To truly support 16-bit VGA decode, all the PCIto-
+///       PCI bridges that are upstream to a VGA device, as well as

+
+  Callers to this protocol must be at a TPL_APPLICATION task priority level.
+  This is the base PCD service API that provides an abstraction for accessing configuration content in
+  the platform. It a seamless mechanism for extracting information regardless of where the
+  information is stored (such as in Read-only data, or an EFI Variable).
+  This protocol allows access to data through size-granular APIs and provides a mechanism for a
+  firmware component to monitor specific settings and be alerted when a setting is changed.

+                              parameter that may be NULL. It will be
+                              NULL for device drivers and for bus
+                              drivers that attempt to get options for
+                              the bus controller. It will not be NULL
+                              for a bus driver that attempts to get
+                              options for one of its child controllers.

+                              increment this value by one each time to retrieve
+                              successive data.
+
+  @param ParameterTypeGuid    An EFI_GUID that defines the contents
+                              of ParameterBlock. UEFI drivers must
+                              use the ParameterTypeGuid to determine
+                              how to parse the ParameterBlock. The caller
+                              should not attempt to free ParameterTypeGuid.
+
+  @param ParameterBlock       The platform returns a pointer to the
+                              ParameterBlock structure which
+                              contains details about the
+                              configuration parameters specific to
+                              the ParameterTypeGuid. This structure
+                              is defined based on the protocol and
+                              may be different for different
+                              protocols. UEFI driver decodes this
+                              structure and its contents based on
+                              ParameterTypeGuid. ParameterBlock is
+                              allocated by the platform and the
+                              platform is responsible for freeing
+                              the ParameterBlock after Result is
+                              called.
+

+  Used to perform TFTP and MTFTP services.
+
+  This function is used to perform TFTP and MTFTP services. This includes the
+  TFTP operations to get the size of a file, read a directory, read a file, and
+  write a file. It also includes the MTFTP operations to get the size of a file,
+  read a directory, and read a file. The type of operation is specified by Operation.
+  If the callback function that is invoked during the TFTP/MTFTP operation does
+  not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
+  be returned.
+  For read operations, the return data will be placed in the buffer specified by
+  BufferPtr. If BufferSize is too small to contain the entire downloaded file,
+  then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
+  or the size of the requested file (the size of the requested file is only returned
+  if the TFTP server supports TFTP options). If BufferSize is large enough for the
+  read operation, then BufferSize will be set to the size of the downloaded file,
+  and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
+  should use the get-file-size operations to determine the size of the downloaded
+  file prior to using the read-file operations--especially when downloading large
+  (greater than 64 MB) files--instead of making two calls to the read-file operation.
+  Following this recommendation will save time if the file is larger than expected
+  and the TFTP server does not support TFTP option extensions. Without TFTP option
+  extension support, the client has to download the entire file, counting and discarding
+  the received packets, to determine the file size.
+  For write operations, the data to be sent is in the buffer specified by BufferPtr.
+  BufferSize specifies the number of bytes to send. If the write operation completes
+  successfully, then EFI_SUCCESS will be returned.
+  For TFTP "get file size" operations, the size of the requested file or directory
+  is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
+  does not support options, the file will be downloaded into a bit bucket and the
+  length of the downloaded file will be returned. For MTFTP "get file size" operations,
+  if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
+  will be returned.
+  This function can take up to 10 seconds to timeout and return control to the caller.
+  If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
+  If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
+  then the TFTP sequence is stopped and EFI_ABORTED will be returned.
+  The format of the data returned from a TFTP read directory operation is a null-terminated
+  filename followed by a null-terminated information string, of the form
+  "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
+  the seconds field can be a decimal number), where the date and time are UTC. For
+  an MTFTP read directory command, there is additionally a null-terminated multicast
+  IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
+  entry is itself null-terminated, so that the final information string is terminated
+  with two null octets.
+
+  @param  This                  The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance.
+  @param  Operation             The type of operation to perform.
+  @param  BufferPtr             A pointer to the data buffer.
+  @param  Overwrite             Only used on write file operations. TRUE if a file on a remote server can
+                                be overwritten.
+  @param  BufferSize            For get-file-size operations, *BufferSize returns the size of the
+                                requested file.
+  @param  BlockSize             The requested block size to be used during a TFTP transfer.
+  @param  ServerIp              The TFTP / MTFTP server IP address.
+  @param  Filename              A Null-terminated ASCII string that specifies a directory name or a file
+                                name.
+  @param  Info                  The pointer to the MTFTP information.

+
+  The EFI_S3_SMM_SAVE_STATE_PROTOCOL publishes the PI SMMboot script abstractions
+  On an S3 resume boot path the data stored via this protocol is replayed in the order it was stored.
+  The order of replay is the order either of the S3 Save State Protocol or S3 SMM Save State Protocol
+  Write() functions were called during the boot process. Insert(), Label(), and
+  Compare() operations are ordered relative other S3 SMM Save State Protocol write() operations
+  and the order relative to S3 State Save Write() operations is not defined. Due to these ordering
+  restrictions it is recommended that the S3 State Save Protocol be used during the DXE phase when
+  every possible.
+  The EFI_S3_SMM_SAVE_STATE_PROTOCOL can be called at runtime and
+  EFI_OUT_OF_RESOURCES may be returned from a runtime call. It is the responsibility of the
+  platform to ensure enough memory resource exists to save the system state. It is recommended that
+  runtime calls be minimized by the caller.

+  SCSI Pass Through protocol as defined in EFI 1.1.
+  This protocol allows information about a SCSI channel to be collected,
+  and allows SCSI Request Packets to be sent to any SCSI devices on a SCSI
+  channel even if those devices are not boot devices. This protocol is attached
+  to the device handle of each SCSI channel in a system that the protocol
+  supports, and can be used for diagnostics. It may also be used to build
+  a Block I/O driver for SCSI hard drives and SCSI CD-ROM or DVD drives to
+  allow those devices to become boot devices.

+  Used to provide Security services.  Specifically, dependening upon the
+  authentication state of a discovered driver in a Firmware Volume, the
+  portable DXE Core Dispatcher will call into the Security Architectural
+  Protocol (SAP) with the authentication state of the driver.
+
+  This call-out allows for OEM-specific policy decisions to be made, such
+  as event logging for attested boots, locking flash in response to discovering
+  an unsigned driver or failed signature check, or other exception response.
+
+  The SAP can also change system behavior by having the DXE core put a driver
+  in the Schedule-On-Request (SOR) state.  This will allow for later disposition
+  of the driver by platform agent, such as Platform BDS.

+/**
+  The function reads the next keystroke from the input device. If
+  there is no pending keystroke the function returns
+  EFI_NOT_READY. If there is a pending keystroke, then
+  KeyData.Key.ScanCode is the EFI scan code defined in Error!
+  Reference source not found. The KeyData.Key.UnicodeChar is the
+  actual printable character or is zero if the key does not
+  represent a printable character (control key, function key,
+  etc.). The KeyData.KeyState is shift state for the character
+  reflected in KeyData.Key.UnicodeChar or KeyData.Key.ScanCode .
+  When interpreting the data from this function, it should be
+  noted that if a class of printable characters that are
+  normally adjusted by shift modifiers (e.g. Shift Key + "f"
+  key) would be presented solely as a KeyData.Key.UnicodeChar
+  without the associated shift state. So in the previous example
+  of a Shift Key + "f" key being pressed, the only pertinent
+  data returned would be KeyData.Key.UnicodeChar with the value
+  of "F". This of course would not typically be the case for
+  non-printable characters such as the pressing of the Right
+  Shift Key + F10 key since the corresponding returned data
+  would be reflected both in the KeyData.KeyState.KeyShiftState
+  and KeyData.Key.ScanCode values. UEFI drivers which implement
+  the EFI_SIMPLE_TEXT_INPUT_EX protocol are required to return
+  KeyData.Key and KeyData.KeyState values. These drivers must
+  always return the most current state of
+  KeyData.KeyState.KeyShiftState and
+  KeyData.KeyState.KeyToggleState. It should also be noted that
+  certain input devices may not be able to produce shift or toggle
+  state information, and in those cases the high order bit in the
+  respective Toggle and Shift state fields should not be active.

+  SMBIOS Protocol as defined in PI1.2 Specification VOLUME 5 Standard.
+
+  SMBIOS protocol allows consumers to log SMBIOS data records, and enables the producer
+  to create the SMBIOS tables for a platform.
+
+  This protocol provides an interface to add, remove or discover SMBIOS records. The driver which
+  produces this protocol is responsible for creating the SMBIOS data tables and installing the pointer
+  to the tables in the EFI System Configuration Table.
+  The caller is responsible for only adding SMBIOS records that are valid for the SMBIOS
+  MajorVersion and MinorVersion. When an enumerated SMBIOS field's values are
+  controlled by the DMTF, new values can be used as soon as they are defined by the DMTF without
+  requiring an update to MajorVersion and MinorVersion.
+  The SMBIOS protocol can only be called a TPL < TPL_NOTIFY.

+/** @file
+  EFI SMM Control2 Protocol as defined in the PI 1.2 specification.
+
+  This protocol is used initiate synchronous SMI activations. This protocol could be published by a
+  processor driver to abstract the SMI IPI or a driver which abstracts the ASIC that is supporting the
+  APM port. Because of the possibility of performing SMI IPI transactions, the ability to generate this
+  event from a platform chipset agent is an optional capability for both IA-32 and x64-based systems.
+
+  The EFI_SMM_CONTROL2_PROTOCOL is produced by a runtime driver. It provides  an
+  abstraction of the platform hardware that generates an SMI.  There are often I/O ports that, when
+  accessed, will generate the SMI.  Also, the hardware optionally supports the periodic generation of
+  these signals.

+/** @file
+  The USB Function Protocol provides an I/O abstraction for a USB Controller
+  operating in Function mode (also commonly referred to as Device, Peripheral,
+  or Target mode) and the mechanisms by which the USB Function can communicate
+  with the USB Host. It is used by other UEFI drivers or applications to
+  perform data transactions and basic USB controller management over a USB
+  Function port.
+
+  This simple protocol only supports USB 2.0 bulk transfers on systems with a
+  single configuration and a single interface. It does not support isochronous
+  or interrupt transfers, alternate interfaces, or USB 3.0 functionality.
+  Future revisions of this protocol may support these or additional features.

+  @note
+  CPUID leaf 1FH is a preferred superset to leaf 0BH. Intel recommends first
+  checking for the existence of Leaf 1FH before using leaf 0BH.
+  Most of Leaf 0BH output depends on the initial value in ECX.  The EDX output
+  of leaf 0BH is always valid and does not vary with input value in ECX.  Output
+  value in ECX[7:0] always equals input value in ECX[7:0].
+  Sub-leaf index 0 enumerates SMT level. Each subsequent higher sub-leaf index
+  enumerates a higher-level topological entity in hierarchical order.
+  For sub-leaves that return an invalid level-type of 0 in ECX[15:8]; EAX and
+  EBX will return 0.
+  If an input value n in ECX returns the invalid level-type of 0 in ECX[15:8],
+  other input values with ECX > n also return 0 in ECX[15:8].

+  CPUID V2 Extended Topology Enumeration Leaf
+
+  @note
+  CPUID leaf 1FH is a preferred superset to leaf 0BH. Intel recommends first checking
+  for the existence of Leaf 1FH and using this if available.
+  Most of Leaf 1FH output depends on the initial value in ECX. The EDX output of leaf
+  1FH is always valid and does not vary with input value in ECX. Output value in ECX[7:0]
+  always equals input value in ECX[7:0]. Sub-leaf index 0 enumerates SMT level. Each
+  subsequent higher sub-leaf index enumerates a higher-level topological entity in
+  hierarchical order. For sub-leaves that return an invalid level-type of 0 in ECX[15:8];
+  EAX and EBX will return 0. If an input value n in ECX returns the invalid level-type of
+  0 in ECX[15:8], other input values with ECX > n also return 0 in ECX[15:8].
+
+  Software should use this field (EAX[4:0]) to enumerate processor topology of the system.
+  Software must not use EBX[15:0] to enumerate processor topology of the system. This value
+  in this field (EBX[15:0]) is only intended for display/diagnostic purposes. The actual
+  number of logical processors available to BIOS/OS/Applications may be different from the
+  value of EBX[15:0], depending on software and platform hardware configurations.

+  Since the normal OS environment runs with a different set of page tables than
+  the SMM guest, virtual mappings will certainly be different. In order to do a
+  guest virtual to host physical translation of an address from the normal OS
+  code (EIP for example), it is necessary to walk the page tables governing the
+  OS page mappings. Since the SMM guest has no direct access to the page tables,
+  it must ask the STM to do this page table walk. This is supported via the
+  StmAddressLookup VMCALL. All OS page table formats need to be supported,
+  (e.g. PAE, PSE, Intel64, EPT, etc.)
+
+  StmAddressLookup takes a CR3 value and a virtual address from the interrupted
+  code as input and returns the corresponding physical address. It also
+  optionally maps the physical address into the SMM guest's virtual address
+  space. This new mapping persists ONLY for the duration of the SMI and if
+  needed in subsequent SMIs it must be remapped. PAT cache types follow the
+  interrupted environment's page table.
+
+  If EPT is enabled, OS CR3 only provides guest physical address information,
+  but the SMM guest might also need to know the host physical address. Since
+  SMM does not have direct access rights to EPT (it is protected by the STM),
+  SMM can input InterruptedEptp to let STM help to walk through it, and output
+  the host physical address.

+  resume the SMM guest again with the specified register state.
+

+
+  If the SMM guest STM protection exception handler itself causes a protection
+  exception (e.g. a single nested exception), or more than 100 un-nested

+; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
+; For example, to define a structure called mytype containing a longword,
+; a word, a byte and a string of bytes, you might code
+;
+; struc   mytype
+;
+;  mt_long:      resd    1
+;  mt_word:      resw    1
+;  mt_byte:      resb    1
+;  mt_str:       resb    32
+;
+; endstruc
+;
+; Below macros are help to map the C types and the RESB family of pseudo-instructions.
+; So that the above structure definition can be coded as
+;

+  using the new stack specified by NewStack and passing in the parameters
+  specified by Context1 and Context2. Context1 and Context2 are optional and
+  may be NULL. The function EntryPoint must never return.
+
+  There are a number of constraints that must be followed before calling this
+  function:
+  1)  Interrupts must be disabled.
+  2)  The caller must be in 32-bit paged mode.
+  3)  CR0, CR3, and CR4 must be compatible with 32-bit paged mode.
+  4)  CR3 must point to valid page tables that guarantee that the pages for
+      this function and the stack are identity mapped.
+
+  @param  EntryPoint  A pointer to function to call with the new stack after
+                      paging is disabled.
+  @param  Context1    A pointer to the context to pass into the EntryPoint
+                      function as the first parameter after paging is disabled.
+  @param  Context2    A pointer to the context to pass into the EntryPoint
+                      function as the second parameter after paging is
+                      disabled.
+  @param  NewStack    A pointer to the new stack to use for the EntryPoint
+                      function after paging is disabled.

+  Enables the 32-bit paging mode on the CPU.
+
+  Enables the 32-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables
+  must be properly initialized prior to calling this service. This function
+  assumes the current execution mode is 32-bit protected mode. This function is
+  only available on IA-32. After the 32-bit paging mode is enabled, control is
+  transferred to the function specified by EntryPoint using the new stack
+  specified by NewStack and passing in the parameters specified by Context1 and
+  Context2. Context1 and Context2 are optional and may be NULL. The function
+  EntryPoint must never return.
+
+  There are a number of constraints that must be followed before calling this
+  function:
+  1)  Interrupts must be disabled.
+  2)  The caller must be in 32-bit protected mode with flat descriptors. This
+      means all descriptors must have a base of 0 and a limit of 4GB.
+  3)  CR0 and CR4 must be compatible with 32-bit protected mode with flat
+      descriptors.
+  4)  CR3 must point to valid page tables that will be used once the transition
+      is complete, and those page tables must guarantee that the pages for this
+      function and the stack are identity mapped.
+
+  @param  EntryPoint  A pointer to function to call with the new stack after
+                      paging is enabled.
+  @param  Context1    A pointer to the context to pass into the EntryPoint
+                      function as the first parameter after paging is enabled.
+  @param  Context2    A pointer to the context to pass into the EntryPoint
+                      function as the second parameter after paging is enabled.
+  @param  NewStack    A pointer to the new stack to use for the EntryPoint
+                      function after paging is enabled.

+  Convert a Null-terminated Ascii hexadecimal string to a value of type UINT64.
+
+  This function outputs a value of type UINT64 by interpreting the contents of
+  the Ascii string specified by String as a hexadecimal number. The format of
+  the input Ascii string String is:
+
+                  [spaces][zeros][x][hexadecimal digits].
+
+  The valid hexadecimal digit character is in the range [0-9], [a-f] and [A-F].
+  The prefix "0x" is optional. Both "x" and "X" is allowed in "0x" prefix. If
+  "x" appears in the input string, it must be prefixed with at least one 0. The
+  function will ignore the pad space, which includes spaces or tab characters,
+  before [zeros], [x] or [hexadecimal digits]. The running zero before [x] or
+  [hexadecimal digits] will be ignored. Then, the decoding starts after [x] or
+  the first valid hexadecimal digit. Then, the function stops at the first
+  character that is a not a valid hexadecimal character or Null-terminator,
+  whichever on comes first.
+
+  If String has no valid hexadecimal digits in the above format, then 0 is
+  stored at the location pointed to by Data.
+  If the number represented by String exceeds the range defined by UINT64, then
+  MAX_UINT64 is stored at the location pointed to by Data.
+
+  If EndPointer is not NULL, a pointer to the character that stopped the scan
+  is stored at the location pointed to by EndPointer. If String has no valid
+  hexadecimal digits right after the optional pad spaces, the value of String
+  is stored at the location pointed to by EndPointer.

+  Convert a Null-terminated ASCII string to IPv6 address and prefix length.

+
+  X contains one to four hexadecimal digit characters in the range [0-9], [a-f] and
+  [A-F]. X is converted to a value of type UINT16, whose low byte is stored in low
+  memory address and high byte is stored in high memory address. P contains decimal
+  digit characters in the range [0-9]. The running zero in the beginning of P will
+  be ignored. /P is optional.
+
+  When /P is not in the String, the function stops at the first character that is

+
+  When /P is in the String, the function stops at the first character that is not
+  a valid decimal digit character after P is converted.
+
+  "::" can be used to compress one or more groups of X when X contains only 0.
+  The "::" can only appear once in the String.
+

+  to the character that stopped the scan is stored at the location pointed to
+  by EndPointer.
+
+  @param  String                   Pointer to a Null-terminated ASCII string.

+                                   length. MAX_UINT8 is returned when /P is
+                                   not in the String.

+    PatchInstructionX86 (gPatchCr3, AsmReadCr3 (), 4);
+
+  @param[out] InstructionEnd  Pointer right past the instruction to patch. The

+                              ValueSize permits, then ASSERT().
+
+  @param[in] PatchValue       The constant to write to the immediate operand.
+                              The caller is responsible for ensuring that

+                              ValueSize); otherwise ASSERT().
+

+  Transfers control to a 16-bit real mode entry point and returns the results.
+  AsmPrepareThunk16() must be called with ThunkContext before this function is used.
+  This function must be called with interrupts disabled.
+
+  The register state from the RealModeState field of ThunkContext is restored just prior
+  to calling the 16-bit real mode entry point.  This includes the EFLAGS field of RealModeState,
+  which is used to set the interrupt state when a 16-bit real mode entry point is called.
+  Control is transferred to the 16-bit real mode entry point specified by the CS and Eip fields of RealModeState.
+  The stack is initialized to the SS and ESP fields of RealModeState.  Any parameters passed to
+  the 16-bit real mode code must be populated by the caller at SS:ESP prior to calling this function.
+  The 16-bit real mode entry point is invoked with a 16-bit CALL FAR instruction,
+  so when accessing stack contents, the 16-bit real mode code must account for the 16-bit segment
+  and 16-bit offset of the return address that were pushed onto the stack. The 16-bit real mode entry
+  point must exit with a RETF instruction. The register state is captured into RealModeState immediately
+  after the RETF instruction is executed.
+
+  If EFLAGS specifies interrupts enabled, or any of the 16-bit real mode code enables interrupts,
+  or any of the 16-bit real mode code makes a SW interrupt, then the caller is responsible for making sure
+  the IDT at address 0 is initialized to handle any HW or SW interrupts that may occur while in 16-bit real mode.
+
+  If EFLAGS specifies interrupts enabled, or any of the 16-bit real mode code enables interrupts,
+  then the caller is responsible for making sure the 8259 PIC is in a state compatible with 16-bit real mode.
+  This includes the base vectors, the interrupt masks, and the edge/level trigger mode.
+
+  If THUNK_ATTRIBUTE_BIG_REAL_MODE is set in the ThunkAttributes field of ThunkContext, then the user code
+  is invoked in big real mode.  Otherwise, the user code is invoked in 16-bit real mode with 64KB segment limits.
+
+  If neither THUNK_ATTRIBUTE_DISABLE_A20_MASK_INT_15 nor THUNK_ATTRIBUTE_DISABLE_A20_MASK_KBD_CTRL are set in
+  ThunkAttributes, then it is assumed that the user code did not enable the A20 mask, and no attempt is made to
+  disable the A20 mask.
+
+  If THUNK_ATTRIBUTE_DISABLE_A20_MASK_INT_15 is set and THUNK_ATTRIBUTE_DISABLE_A20_MASK_KBD_CTRL is clear in
+  ThunkAttributes, then attempt to use the INT 15 service to disable the A20 mask.  If this INT 15 call fails,

+  Base PE/COFF loader supports loading any PE32/PE32+ or TE image, but

+
+  Caution: This file requires additional review when modified.
+  This library will have external input - PE/COFF image.
+  This external input must be validated carefully to avoid security issue like
+  buffer overflow, integer overflow.
+
+  The basic guideline is that caller need provide ImageContext->ImageRead () with the

+  PE image buffer is always in valid range.
+  This library will also do some additional check for PE header fields.
+
+  PeCoffLoaderGetPeHeader() routine will do basic check for PE/COFF header.
+  PeCoffLoaderGetImageInfo() routine will do basic check for whole PE/COFF image.

+  Loads a PE/COFF image into memory.
+
+  Loads the PE/COFF image accessed through the ImageRead service of ImageContext into the buffer
+  specified by the ImageAddress and ImageSize fields of ImageContext.  The caller must allocate
+  the load buffer and fill in the ImageAddress and ImageSize fields prior to calling this function.
+  The EntryPoint, FixupDataSize, CodeView, PdbPointer and HiiResourceData fields of ImageContext are computed.
+  The ImageRead, Handle, PeCoffHeaderOffset,  IsTeImage,  Machine, ImageType, ImageAddress, ImageSize,
+  DestinationAddress, RelocationsStripped, SectionAlignment, SizeOfHeaders, and DebugDirectoryEntryRva
+  fields of the ImageContext structure must be valid prior to invoking this service.
+
+  If ImageContext is NULL, then ASSERT().
+
+  Note that if the platform does not maintain coherency between the instruction cache(s) and the data
+  cache(s) in hardware, then the caller is responsible for performing cache maintenance operations
+  prior to transferring control to a PE/COFF image that is loaded using this library.

+                                    the ImageAddress and ImageSize fields of ImageContext.
+                                    Extended status information is in the ImageError field of ImageContext.

+  This function reapplies relocation fixups to the PE/COFF image specified by ImageBase

+  after this PE/COFF image was relocated with PeCoffLoaderRelocateImage().
+
+  Note that if the platform does not maintain coherency between the instruction cache(s) and the data
+  cache(s) in hardware, then the caller is responsible for performing cache maintenance operations
+  prior to transferring control to a PE/COFF image that is loaded using this library.
+
+  @param  ImageBase          The base address of a PE/COFF image that has been loaded
+                             and relocated into system memory.

+                             be fixed up for.
+  @param  ImageSize          The size, in bytes, of the PE/COFF image.

+  Execute Test Unit Ready SCSI command on a specific SCSI target.
+
+  Executes the Test Unit Ready command on the SCSI target specified by ScsiIo.

+  If ScsiIo is NULL, then ASSERT().
+  If SenseDataLength is NULL, then ASSERT().
+  If HostAdapterStatus is NULL, then ASSERT().
+  If TargetStatus is NULL, then ASSERT().
+
+  If SenseDataLength is non-zero and SenseData is not NULL, SenseData must meet buffer

+                                    of this SCSI Request Packet. A Timeout value of
+                                    zero means that this function will wait indefinitely
+                                    for the SCSI Request Packet to execute. If Timeout
