Agyeman, Prince posted 5 patches 6 years, 4 months ago
There is a newer version of this series
[edk2-devel] [edk2-platforms] [PATCH 3/5] KabylakeOpenBoardPkg/GalagoPro3: Add BiosInfo PEIM
Posted by Agyeman, Prince 6 years, 4 months ago 
Added BiosInfo PEIM to publish the
Bios Info HOB. Currently this PEIM publishes
one Bios Info entry which is the microcode
region information.

Re: [edk2-devel] [edk2-platforms] [PATCH 3/5] KabylakeOpenBoardPkg/GalagoPro3: Add BiosInfo PEIM
Posted by Nate DeSimone 6 years, 4 months ago 
Platform/Intel/KabylakeOpenBoardPkg/KabylakeRvp3/BiosInfo/BiosInfo.c and Platform/Intel/KabylakeOpenBoardPkg/GalagoPro3/BiosInfo/BiosInfo.c are identical files. Can we move this up to the parent KabylakeOpenBoardPkg and use one PEIM for both platforms?
