-/* The coreboot table information is for conveying information
- * from the firmware to the loaded OS image. Primarily this
- * is expected to be information that cannot be discovered by
- * other means, such as quering the hardware directly.
- *
- * All of the information should be Position Independent Data.
- * That is it should be safe to relocated any of the information
- * without it's meaning/correctnes changing. For table that
- * can reasonably be used on multiple architectures the data
- * size should be fixed. This should ease the transition between
- * 32 bit and 64 bit architectures etc.
- *
- * The completeness test for the information in this table is:
- * - Can all of the hardware be detected?
- * - Are the per motherboard constants available?
- * - Is there enough to allow a kernel to run that was written before
- * a particular motherboard is constructed? (Assuming the kernel
- * has drivers for all of the hardware but it does not have
- * assumptions on how the hardware is connected together).
- *
- * With this test it should be straight forward to determine if a
- * table entry is required or not. This should remove much of the
- * long term compatibility burden as table entries which are
- * irrelevant or have been replaced by better alternatives may be
- * dropped. Of course it is polite and expidite to include extra
- * table entries and be backwards compatible, but it is not required.

-/* Since coreboot is usually compiled 32bit, gcc will align 64bit
- * types to 32bit boundaries. If the coreboot table is dumped on a
- * 64bit system, a uint64_t would be aligned to 64bit boundaries,
- * breaking the table format.
- *
- * lb_uint64 will keep 64bit coreboot table values aligned to 32bit
- * to ensure compatibility. They can be accessed with the two functions
- * below: unpack_lb64() and pack_lb64()
- *
- * See also: util/lbtdump/lbtdump.c
