/* The linuxbios table information is for conveying information

*
* 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* irrelevant or have been replaced by better alternatives may be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
