First attempt at shedding some light on the MCP67 SPI situation.
Huge thanks to Michael Karcher for reverse engineering the chipset and
writing a spec. Due to this, we were able to use the chinese wall
technique for 100% clean room reverse engineering.
This patch doesn't touch any of the new registers, it only reads them.
Assuming that read has no side effects, this patch is a no-op and safe.
We need "flashrom -V" output from MCP67 boards with SPI flash and from
boards with LPC flash. Note: That output is only helpful if it is
created with patched flashrom and if is from the first run of flashrom
after a cold boot (reset or Ctrl-Alt-Del is not sufficient). I hope to
see a pattern based on which we can detect which flash type is present
on the board.
Alex, we need this output (as described above) from your Asus M2N68-VM
board.
I'd like to merge this ASAP and then ping everyone who had this chipset
to get flashrom -V output.
Hello Carl,
I got latest sources from trunk, applied the provided patch, cold-booted
and saved the output of flashrom -V (attached).
I hope this helps,
Alex

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.
