It serves a similar role.  I don't much like CMOS because I've found
it flaky on boards.  I also want to be able to config boot order - for
example, a boot order might be something like
"cdrom,disk,pci00:13.1,floppy" for cdrom, hard drive, BEV on an
optionrom (eg, nic), and floppy.  Hard drive order might be like
"ata1-0,usb1234:4567,pci00:13.1/1" for an ata drive, USB drive, and a
BCV on an optionrom (eg, scsi drive).  I think encoding this into CMOS
would be a lot harder than encoding into a string in CBFS.

Anyway, this is just in the though phase.  I only raised it because I
thought it might be a sibling to the proposed "add-lzma".
