/* As extracted from the manufacturer's ROM, the romstrap table looks like:
* .long 0x77886047 .long 0x00777777
* .long 0x00000000 .long 0x00000000
* .long 0x00888888 .long 0x00AA1111
* .long 0x00000000 .long 0x00000000
*
* The vendor BIOS then adjusts some of these settings very early on. Instead of
* adjusting those settings in code, we work them in the romstrap table.
