Hi Yinghai,
is there any public information about the usage of the top 256 bytes in
ROM for Nvidia chipsets? The only information I found was
http://coreboot.org/pipermail/coreboot/2005-November/012918.html but
that does not explain the reasons or give me a memory map.
I'm looking at this diff and wonder if 0x80 is the only possible
location for ID information in the ROM.
