OvmfPkg IA32: add support for loading X64 images This is the UEFI counterpart to my Linux series which generalizes mixed mode support into a feature that requires very little internal knowledge about the architecture specifics of booting Linux on the part of the bootloader or firmware. Instead, we add a .compat PE/COFF header containing an array of PE_COMPAT nodes containing <machine type, entrypoint> tuples that describe alternate entrypoints into the image for different native machine types, e.g., IA-32 in a 64-bit image so it can be booted from IA-32 firmware. This patch implements the PE/COFF emulator protocol to take this new section into account, so that such images can simply be loaded via LoadImage/StartImage, e.g., straight from the shell. This feature is based on the EDK2 specific PE/COFF emulator protocol that was introduced in commit 57df17fe26cd ("MdeModulePkg/DxeCore: invoke the emulator protocol for foreign images", 2019-04-14).
