Re: [flashrom] SB700 - register to avoid issue due to IMC

[Carl-Daniel Hailfinger]

Hi Frederic,

I had a patch for SB700 IMC arbitration. Unfortunately it did not work:
http://patchwork.coreboot.org/patch/1768/

IIRC my old patch uses BiosSemaphore, but maybe HostOwnLPC works better?
You could modify my old patch to use HostOwnLPC, and test if that fixes
the issue. The biggest problem is that BiosSemaphore only protects
against write, but we have to protect against read as well because it
uses the same internal registers in the chipset.
