Description
This change adds a parser for the
MSEG_SMRAM_HOBso that the SMM can program the MSEG MSR during the first MMI entry.This change also exposed the
efi_mainto make it discoverable in the PDB file.How This Was Tested
This was tested on a customized QEMU Q35 platform and booted to UEFI shell.
Integration Instructions
For platforms elect to support SEA, integrate the MSEG prepare PEI into the platform and link the STM based CPU feature library into the MM initializer.
