UefiCpuPkg/MpInitLib: Add AP assembly code and MP_CPU_EXCHANGE_INFO
Add assembly code for AP reset vector and the definition of MP_CPU_EXCHANGE_INFO that are used to exchange the data between C code and assembly code when AP wake up. v4: 1. Copy MP_CPU_EXCHANGE_INFO from UefiCpuPkg/CpuMpPei/CpuMpPei.h 2. Copy MpEqu.inc and MpFuncs.nasm from UefiCpuPkg/CpuMpPei. v3: 1. Rename NumApsExecutingLoction to NumApsExecutingLocation 2. Add whitespace after ; in .nasm file Cc: Michael Kinney <michael.d.kinney@intel.com> Cc: Feng Tian <feng.tian@intel.com> Cc: Giri P Mudusuru <giri.p.mudusuru@intel.com> Cc: Laszlo Ersek <lersek@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jeff Fan <jeff.fan@intel.com> Reviewed-by: Michael Kinney <michael.d.kinney@intel.com> Tested-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Michael Kinney <michael.d.kinney@intel.com>
