+ * set" (LBA48), in which case each of these byte-wide registers is
+ * actually a two-entry FIFO, and the "previous" byte pushed into the

+ * 0x56 -> LBA Low register
+ * 0xef -> LBA Low register
+ * 0x34 -> LBA Mid register
+ * 0xcd -> LBA Mid register
+ * 0x12 -> LBA High register
+ * 0xab -> LBA High register
+ *
+ * This structure encapsulates this information by providing a single
+ * 64-bit integer in native byte order, unioned with bytes named so
+ * that the sequence becomes
+ *
+ * low_prev -> LBA Low register
+ * low_cur -> LBA Low register
+ * mid_prev -> LBA Mid register
+ * mid_cur -> LBA Mid register
+ * high_prev -> LBA High register
+ * high_cur -> LBA High register
+ *
+ * Just to complicate matters further, in non-LBA48 mode it is
+ * possible to have a 28-bit address, in which case bits 27:24 must be
+ * written into the low four bits of the Device register.

+/** @page ifdef_harmful #ifdef considered harmful
+ *
+ * Overuse of @c #ifdef has long been a problem in Etherboot.
+ * Etherboot provides a rich array of features, but all these features
+ * take up valuable space in a ROM image. The traditional solution to
+ * this problem has been for each feature to have its own @c #ifdef
+ * option, allowing the feature to be compiled in only if desired.
+ *
+ * The problem with this is that it becomes impossible to compile, let
+ * alone test, all possible versions of Etherboot. Code that is not
+ * typically used tends to suffer from bit-rot over time. It becomes
+ * extremely difficult to predict which combinations of compile-time
+ * options will result in code that can even compile and link
+ * correctly.
+ *
+ * To solve this problem, we have adopted a new approach from
+ * Etherboot 5.5 onwards. @c #ifdef is now "considered harmful", and
+ * its use should be minimised. Separate features should be
+ * implemented in separate @c .c files, and should \b always be
+ * compiled (i.e. they should \b not be guarded with a @c #ifdef @c
+ * MY_PET_FEATURE statement). By making (almost) all code always
+ * compile, we avoid the problem of bit-rot in rarely-used code.
+ *
+ * The file config.h, in combination with the @c make command line,
+ * specifies the objects that will be included in any particular build
+ * of Etherboot. For example, suppose that config.h includes the line
+ *
+ * @code
+ *
+ * #define CONSOLE_SERIAL
+ * #define DOWNLOAD_PROTO_TFTP
+ *
+ * @endcode
+ *
+ * When a particular Etherboot image (e.g. @c bin/rtl8139.zdsk) is
+ * built, the options specified in config.h are used to drag in the
+ * relevant objects at link-time. For the above example, serial.o and
+ * tftp.o would be linked in.
+ *
+ * There remains one problem to solve: how do these objects get used?
+ * Traditionally, we had code such as
+ *
+ * @code
+ *
+ * #ifdef CONSOLE_SERIAL
+ * serial_init();
+ * #endif
+ *
+ * @endcode
+ *
+ * in main.c, but this reintroduces @c #ifdef and so is a Bad Idea.
+ * We cannot simply remove the @c #ifdef and make it
+ *
+ * @code
+ *
+ * serial_init();
+ *
+ * @endcode
+ *
+ * because then serial.o would end up always being linked in.
+ *
+ * The solution is to use @link tables.h linker tables @endlink.
+ *
+ */
+
+/** @file
+ *
+ * Linker tables
+ *
+ * Read @ref ifdef_harmful first for some background on the motivation
+ * for using linker tables.
+ *
+ * This file provides macros for dealing with linker-generated tables
+ * of fixed-size symbols. We make fairly extensive use of these in
+ * order to avoid @c #ifdef spaghetti and/or linker symbol pollution.
+ * For example, instead of having code such as
+ *
+ * @code
+ *
+ * #ifdef CONSOLE_SERIAL
+ * serial_init();
+ * #endif
+ *
+ * @endcode
+ *
+ * we make serial.c generate an entry in the initialisation function
+ * table, and then have a function call_init_fns() that simply calls
+ * all functions present in this table. If and only if serial.o gets
+ * linked in, then its initialisation function will be called. We
+ * avoid linker symbol pollution (i.e. always dragging in serial.o
+ * just because of a call to serial_init()) and we also avoid @c
+ * #ifdef spaghetti (having to conditionalise every reference to
+ * functions in serial.c).
+ *
+ * The linker script takes care of assembling the tables for us. All
+ * our table sections have names of the format @c .tbl.NAME.NN where
+ * @c NAME designates the data structure stored in the table (e.g. @c
+ * init_fns) and @c NN is a two-digit decimal number used to impose an
+ * ordering upon the tables if required. @c NN=00 is reserved for the
+ * symbol indicating "table start", and @c NN=99 is reserved for the
+ * symbol indicating "table end".
+ *
+ * As an example, suppose that we want to create a "frobnicator"
+ * feature framework, and allow for several independent modules to
+ * provide frobnicating services. Then we would create a frob.h
+ * header file containing e.g.
+ *
+ * @code
+ *
+ * struct frobnicator {
+ * const char *name; // Name of the frobnicator
+ * void ( *frob ) ( void ); // The frobnicating function itself
+ * };
+ *
+ * #define FROBNICATORS __table ( struct frobnicator, "frobnicators" )
+ *
+ * #define __frobnicator __table_entry ( FROBNICATORS, 01 )
+ *
+ * @endcode
+ *
+ * Any module providing frobnicating services would look something
+ * like
+ *
+ * @code
+ *
+ * #include "frob.h"
+ *
+ * static void my_frob ( void ) {
+ * // Do my frobnicating
+ * ...
+ * }
+ *
+ * struct frob my_frobnicator __frobnicator = {
+ * .name = "my_frob",
+ * .frob = my_frob,
+ * };
+ *
+ * @endcode
+ *
+ * The central frobnicator code (frob.c) would use the frobnicating
+ * modules as follows
+ *
+ * @code
+ *
+ * #include "frob.h"
+ *
+ * // Call all linked-in frobnicators
+ * void frob_all ( void ) {
+ * struct frob *frob;
+ *
+ * for_each_table ( frob, FROBNICATORS ) {
+ * printf ( "Calling frobnicator \"%s\"\n", frob->name );
+ * frob->frob ();
+ * }
+ * }
+ *
+ * @endcode
+ *
+ * See init.h and init.c for a real-life example.
