[edk2-devel] [edk2-platforms][PATCH 4/8] Platform/ARM/SgiPkg: remove PcdCoreCount and PcdClusterCount

Thu Mar 12 14:35:16 UTC 2020


The number of CPUs depend on the SGI/RD platform. So instead of
defining a Fixed PCD to specify the value of core and cluster count,
let each platform define these values.
