[coreboot] cmos.layout, nvramtool, options

[Uwe Hermann]

Hi,

please checkout
http://www.coreboot.org/Nvramtool#Commonly_used_CMOS.2FNVRAM_options
where I tried to document all CMOS/NVRAM options coreboot v2 currently
recognizes and uses in the code, as well as options used by FILO and
Etherboot. Any other payloads using NVRAM bits which I missed?

The option table in the wiki may not be complete yet, and it's also
missing a lot of documentation about what the options actually do,
and which boards/chipsets are able to make use of them etc.

Please help filling in the blanks.

Uwe.
