When emulating a full stack of ARM Trusted Firmware, OP-TEE, etc, UEFI will not
be executed from (emulated) NOR flash but loaded in memory at an a priori
unknown memory address and invoked from there.
This implements a version of ArmVirtQemu called ArmVirtQemuKernel which borrows
the self relocation code and early DT parsing code from ArmVirtXen, and jumps
straight from the SEC to the DXE phase as well.
Patch #1 performs some groundwork so that the early PL011 code can be reused
Patch #2 implements a new PlatformLib instance that implements the self
relocation based on the actual load address and the contents of the DT
Patch #3 contains the platform DSC and FDF definitions
Ard Biesheuvel (3):
ArmVirtPkg/EarlyFdtPL011: allow patchable PCD for initial DT base
address
ArmVirtPkg: introduce new ArmQemuRelocatablePlatformLib
ArmVirtPkg: implement ArmVirtQemuKernel
