Re: [edk2-devel] [edk2-platforms] [PATCH v2] SimicsOpenBoardPkg: Add CmosAccessLib to BoardX58Ich10

Posted by Nate DeSimone 1 week ago
It looks like there are a bunch of magical CMOS locations hardcoded in here... specifically 0x34, 0x5B, and 0x5C. I would prefer that these were converted into #defines. That can be done in a separate patch though since it is not related to your change here.
