+ * With GCC 4.5 onwards we can use __builtin_unreachable to indicate to the

+ * optimised out of the generated binary.
+ *
+ * Unfortunately at least GCC 4.6.3 through 7.3.0 inclusive suffer from a bug
+ * that can lead to instructions from beyond an unreachable statement being
+ * incorrectly reordered into earlier delay slots if the unreachable statement
+ * is the only content of a case in a switch statement. This can lead to
+ * seemingly random behaviour, such as invalid memory accesses from incorrectly
+ * reordered loads or stores. See this potential GCC fix for details:
+ *
+ *   https://gcc.gnu.org/ml/gcc-patches/2015-09/msg00360.html
+ *
+ * It is unclear whether GCC 8 onwards suffer from the same issue - nothing
+ * relevant is mentioned in GCC 8 release notes and nothing obviously relevant
+ * stands out in GCC commit logs, but these newer GCC versions generate very
+ * different code for the testcase which doesn't exhibit the bug.
+ *
+ * GCC also handles stack allocation suboptimally when calling noreturn
+ * functions or calling __builtin_unreachable():
+ *
+ *   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82365
+ *
+ * We work around both of these issues by placing a volatile asm statement,
+ * which GCC is prevented from reordering past, prior to __builtin_unreachable
+ * calls.
+ *
+ * The .insn statement is required to ensure that any branches to the
+ * statement, which sadly must be kept due to the asm statement, are known to
+ * be branches to code and satisfy linker requirements for microMIPS kernels.

+ *  - ALL registers are 8 bits only, regardless of transfer size
+ *  - channel 4 is not used - cascades 1 into 2.
+ *  - channels 0-3 are byte - addresses/counts are for physical bytes
+ *  - channels 5-7 are word - addresses/counts are for physical words
+ *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ *  - transfer count loaded to registers is 1 less than actual count
+ *  - controller 2 offsets are all even (2x offsets for controller 1)
+ *  - page registers for 5-7 don't use data bit 0, represent 128K pages
+ *  - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0	  (Physical addresses)
+ *    |	 ...  |	  |  ... |   |	... |
+ *    |	 ...  |	  |  ... |   |	... |

+ *   P7	 ...  P0  A7 ... A0  A7 ... A0
+ * |	Page	| Addr MSB | Addr LSB |	  (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0	   (Physical addresses)
+ *    |	 ...  |	  \   \	  ... \	 \  \  ... \  \

+ * |	  Page	    |  Addr MSB	  |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,

+/*
+ *
+ * Support functions for managing command queues used for
+ * various hardware blocks.
+ *
+ * The common command queue infrastructure abstracts out the
+ * software necessary for adding to Octeon's chained queue
+ * structures. These structures are used for commands to the
+ * PKO, ZIP, DFA, RAID, and DMA engine blocks. Although each
+ * hardware unit takes commands and CSRs of different types,
+ * they all use basic linked command buffers to store the
+ * pending request. In general, users of the CVMX API don't
+ * call cvmx-cmd-queue functions directly. Instead the hardware
+ * unit specific wrapper should be used. The wrappers perform
+ * unit specific validation and CSR writes to submit the
+ * commands.
+ *
+ * Even though most software will never directly interact with
+ * cvmx-cmd-queue, knowledge of its internal working can help
+ * in diagnosing performance problems and help with debugging.
+ *
+ * Command queue pointers are stored in a global named block
+ * called "cvmx_cmd_queues". Except for the PKO queues, each
+ * hardware queue is stored in its own cache line to reduce SMP
+ * contention on spin locks. The PKO queues are stored such that
+ * every 16th queue is next to each other in memory. This scheme
+ * allows for queues being in separate cache lines when there
+ * are low number of queues per port. With 16 queues per port,
+ * the first queue for each port is in the same cache area. The
+ * second queues for each port are in another area, etc. This
+ * allows software to implement very efficient lockless PKO with
+ * 16 queues per port using a minimum of cache lines per core.
+ * All queues for a given core will be isolated in the same
+ * cache area.
+ *
+ * In addition to the memory pointer layout, cvmx-cmd-queue
+ * provides an optimized fair ll/sc locking mechanism for the
+ * queues. The lock uses a "ticket / now serving" model to
+ * maintain fair order on contended locks. In addition, it uses
+ * predicted locking time to limit cache contention. When a core
+ * know it must wait in line for a lock, it spins on the
+ * internal cycle counter to completely eliminate any causes of
+ * bus traffic.

+/**
+ *
+ * Interface to the hardware Packet Output unit.
+ *
+ * Starting with SDK 1.7.0, the PKO output functions now support
+ * two types of locking. CVMX_PKO_LOCK_ATOMIC_TAG continues to
+ * function similarly to previous SDKs by using POW atomic tags
+ * to preserve ordering and exclusivity. As a new option, you
+ * can now pass CVMX_PKO_LOCK_CMD_QUEUE which uses a ll/sc
+ * memory based locking instead. This locking has the advantage
+ * of not affecting the tag state but doesn't preserve packet
+ * ordering. CVMX_PKO_LOCK_CMD_QUEUE is appropriate in most
+ * generic code while CVMX_PKO_LOCK_CMD_QUEUE should be used
+ * with hand tuned fast path code.
+ *
+ * Some of other SDK differences visible to the command queuing:
+ * - PKO indexes are no longer stored in the FAU. A large
+ *   percentage of the FAU register block used to be tied up
+ *   maintaining PKO queue pointers. These are now stored in a
+ *   global named block.
+ * - The PKO <b>use_locking</b> parameter can now have a global
+ *   effect. Since all application use the same named block,
+ *   queue locking correctly applies across all operating
+ *   systems when using CVMX_PKO_LOCK_CMD_QUEUE.
+ * - PKO 3 word commands are now supported. Use
+ *   cvmx_pko_send_packet_finish3().

+/**
+ * Interface to the hardware Packet Order / Work unit.
+ *
+ * New, starting with SDK 1.7.0, cvmx-pow supports a number of
+ * extended consistency checks. The define
+ * CVMX_ENABLE_POW_CHECKS controls the runtime insertion of POW
+ * internal state checks to find common programming errors. If
+ * CVMX_ENABLE_POW_CHECKS is not defined, checks are by default
+ * enabled. For example, cvmx-pow will check for the following
+ * program errors or POW state inconsistency.
+ * - Requesting a POW operation with an active tag switch in
+ *   progress.
+ * - Waiting for a tag switch to complete for an excessively
+ *   long period. This is normally a sign of an error in locking
+ *   causing deadlock.
+ * - Illegal tag switches from NULL_NULL.
+ * - Illegal tag switches from NULL.
+ * - Illegal deschedule request.
+ * - WQE pointer not matching the one attached to the core by
+ *   the POW.

+ *	 for POW stores (i.e. when did<7:3> == 0xc)
+ *     - did<2:0> == 0	    => pending switch bit is set

+ *     - did<2:0> == 3	    => pending switch bit is cleared

+ *     - did<2:0> == others => must not be used
+ *     - No other loads/stores have an affect on the pending switch bit
+ *     - The switch bus from POW can clear the pending switch bit
+ *
+ *  NOTE: did<2:0> == 2 is used by the HW for a special single-cycle
+ *  ADDWQ command that only contains the pointer). SW must never use

+ * per bank.  Each 32bit read accesses one of these banks.  Perhaps HEART was
+ * designed to address up to 8 banks (16 DIMMs)?  We may never know.

+    *  Some general notes:
+    *
+    *  Register addresses are grouped by function and follow the order
+    *  of the User Manual.
+    *
+    *  For the most part, when there is more than one peripheral
+    *  of the same type on the SOC, the constants below will be
+    *  offsets from the base of each peripheral.  For example,
+    *  the MAC registers are described as offsets from the first
+    *  MAC register, and there will be a MAC_REGISTER() macro
+    *  to calculate the base address of a given MAC.
+    *
+    *  The information in this file is based on the BCM1X55/BCM1X80
+    *  User Manual, Document 1X55_1X80-UM100-R, 22/12/03.
+    *
+    *  This file is basically a "what's new" header file.  Since the
+    *  BCM1250 and the new BCM1480 (and derivatives) share many common
+    *  features, this file contains only what's new or changed from
+    *  the 1250.  (above, you can see that we include the 1250 symbols
+    *  to get the base functionality).
+    *
+    *  In software, be sure to use the correct symbols, particularly
+    *  for blocks that are different between the two chip families.
+    *  All BCM1480-specific symbols have _BCM1480_ in their names,
+    *  and all BCM1250-specific and "base" functions that are common in
+    *  both chips have no special names (this is for compatibility with
+    *  older include files).  Therefore, if you're working with the
+    *  SCD, which is very different on each chip, A_SCD_xxx implies
+    *  the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+    *  version.

+    *  Some general notes:
+    *
+    *  This file is basically a "what's new" header file.  Since the
+    *  BCM1250 and the new BCM1480 (and derivatives) share many common
+    *  features, this file contains only what's new or changed from
+    *  the 1250.  (above, you can see that we include the 1250 symbols
+    *  to get the base functionality).
+    *
+    *  In software, be sure to use the correct symbols, particularly
+    *  for blocks that are different between the two chip families.
+    *  All BCM1480-specific symbols have _BCM1480_ in their names,
+    *  and all BCM1250-specific and "base" functions that are common in
+    *  both chips have no special names (this is for compatibility with
+    *  older include files).  Therefore, if you're working with the
+    *  SCD, which is very different on each chip, A_SCD_xxx implies
+    *  the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+    *  version.

+    *  Macros for feature tests, used to enable include file features

+    *  SIBYTE_HDR_FEATURES may be defined to be the mask value chip/revision
+    *  which is to be exposed by the headers.  If undefined, it defaults to
+    *  "all features."
+    *
+    *  Use like:
+    *
+    *	 #define SIBYTE_HDR_FEATURES	SIBYTE_HDR_FMASK_112x_PASS1
+    *
+    *		Generate defines only for that revision of chip.
+    *
+    *	 #if SIBYTE_HDR_FEATURE(chip,pass)
+    *
+    *		True if header features for that revision or later of
+    *		that particular chip type are enabled in SIBYTE_HDR_FEATURES.
+    *		(Use this to bracket #defines for features present in a given
+    *		revision and later.)
+    *
+    *		Note that there is no implied ordering between chip types.
+    *
+    *		Note also that 'chip' and 'pass' must textually exactly
+    *		match the defines below.  So, for example,
+    *		SIBYTE_HDR_FEATURE(112x, PASS1) is OK, but
+    *		SIBYTE_HDR_FEATURE(1120, pass1) is not (for two reasons).
+    *
+    *	 #if SIBYTE_HDR_FEATURE_UP_TO(chip,pass)
+    *
+    *		Same as SIBYTE_HDR_FEATURE, but true for the named revision
+    *		and earlier revisions of the named chip type.
+    *
+    *	 #if SIBYTE_HDR_FEATURE_EXACT(chip,pass)
+    *
+    *		Same as SIBYTE_HDR_FEATURE, but only true for the named
+    *		revision of the named chip type.  (Note that this CANNOT
+    *		be used to verify that you're compiling only for that
+    *		particular chip/revision.  It will be true any time this
+    *		chip/revision is included in SIBYTE_HDR_FEATURES.)
+    *
+    *	 #if SIBYTE_HDR_FEATURE_CHIP(chip)
+    *
+    *		True if header features for (any revision of) that chip type
+    *		are enabled in SIBYTE_HDR_FEATURES.  (Use this to bracket
+    *		#defines for features specific to a given chip type.)
+    *
+    *  Mask values currently include room for additional revisions of each
+    *  chip type, but can be renumbered at will.  Note that they MUST fit
+    *  into 31 bits and may not include C type constructs, for safe use in
+    *  CPP conditionals.  Bit positions within chip types DO indicate
+    *  ordering, so be careful when adding support for new minor revs.

+    *
+    *  V_xxx	       "Value" constant.  This is the same as the

+    *		       shifted to the correct position in the register.
+    *
+    *  S_xxx	       SHIFT constant.	This is the number of bits that

+ * Each BOARD consists of COMPONENTs and the BOARD structure has
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error
+ * information specific to the COMPONENT is present in the respective
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ *
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ * Two types of barrier are provided:

+ *      restrictions imposed by the barrier.
+ *
+ * Ordering barriers can be more efficient than completion barriers, since:
+ *
+ *   a) Ordering barriers only require memory access instructions which preceed
+ *      them in program order (older instructions) to reach a point in the
+ *      load/store datapath beyond which reordering is not possible before
+ *      allowing memory access instructions which follow them (younger

+ *      actually need to complete - they just need to get far enough that all
+ *      other coherent CPUs will observe their completion before they observe
+ *      the effects of younger instructions.
+ *
+ *   b) Multiple variants of ordering barrier are provided which allow the
+ *      effects to be restricted to different combinations of older or younger
+ *      loads or stores. By way of example, if we only care that stores older
+ *      than a barrier are observed prior to stores that are younger than a
+ *      barrier & don't care about the ordering of loads then the 'wmb'
+ *      ordering barrier can be used. Limiting the barrier's effects to stores
+ *      allows loads to continue unaffected & potentially allows the CPU to
+ *      make progress faster than if younger loads had to wait for older stores
