[LinuxBIOS] Flashrom on PCI cards?

[Li-Ta Lo]

Hi,

I may have a need to use flashrom to program the BIOS chip
on a PCI card instead of the main BIOS. Did anyone have a
modified version of flashrom to do this? Devbios used to
do that.

I did the reverse; programmed a flash chip with flashrom and then
soldered it onto a PCI card. :p

flashrom doesn't support it. :\

I know. I am just asking before I am going to implement it myself.

BTW, what is the TS5300 thing? Transmeta? Does it mean the base of
flash rom is always 0x94000000 and grow up according to the size
of flash chip?

#ifdef TS5300
                // FIXME: Wrong place for this decision
                // FIXME: This should be autodetected. It is trivial.
                flash_baseaddr = 0x9400000;
#else
                flash_baseaddr = (0xffffffff - size + 1);
#endif

I planned porting support from ctflasher.sf.net. I have already some
cards which are supported by it.

ctflasher (http://ctflasher.sourceforge.net/) supports some PCI cards.
It's easy to modify it to
support unsupported PCI card provided that you have the datasheet for
the PCI chip.
