Carl-Daniel Hailfinger - 2009-08-06 22:29:51
Stefan found a bug in my patch. New version, still gross, but should
work well enough for debugging.
Chris, please reply with "flashrom -V" output. The patch is against
unmodified flashrom from subversion.

Add ICH6,ICH7,ICH8,ICH9,ICH10 FWH IDSEL settings and flash decode
settings to the debug output. This can help debug cases where the BIOS
does not set up a correct flash decode for the given flash size.
The Intel docs state that the decode applies to FWH and SPI flash.

Hardcode IDSEL=0 for the top 8 MB for now.

No EEPROM/flash device found.
If you know which flash chip you have, and if this version of flashrom
supports a similar flash chip, you can try to force read your chip. Run:
flashrom -f -r -c similar_supported_flash_chip filename

Note: flashrom can never write when the flash chip isn't found 
automatically.

Great, it found the chip. Flashing should work fine, no forcing needed
at all.
