compiling error as below:
w:\edk2\UefiPayloadPkg\UefiPayloadEntry\UefiPayloadEntry.c(140): warning C4244:
'=': conversion from 'UINT64' to 'UINT32', possible
Currently several DXE crash due to invalid memory resource settings.
The PciHostBridgeDxe which expects the MMCONF and PCI Aperature
to be EfiMemoryMappedIO, but currently those regions are (partly)
mapped as EfiReservedMemoryType.
coreboot and slimbootloader provide an e820 compatible memory
