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.

Is this supposed to be a 16bit or 32bit write?

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.

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.

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.
