[edk2-devel] [PATCH v6 33/52] PurleyOpenBoardPkg: Add SpiFlashCommonLib.h

[Michael Kubacki]

Thanks for pointing that out. This was a mistake in copying/pasting 
patch subject lines and your plan to extend WhitleyOpenBoardPkg to use 
IntelSiliconPkg sounds good.

If the package names in the commit message can be corrected before 
pushing that would be great.

Thanks,
Michael
