[edk2-devel] [Patch V2] UefiCpuPkg: Use Top of each AP's stack to save CpuMpData

2022-08-18 Thread Yuanhao Xie
From: Yuanhao Xie To remove the dependency of CPU register, 4/8 byte at the top of the stack is occupied for CpuMpData. BIST information is also taken care here. This modification is only for PEI phase, since in DXE phase CpuMpData is accessed via global variable. Change-Id: I7564279544622617c32
