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
