[PATCH 0/4] MdeModulePkg: add support for dispatching foreign arch PE/COFF images

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

Add the basic plumbing to DXE core, the PCI bus driver and the boot manager
to allow PE/COFF images to be dispatched that target an architecture that is
not native for the platform, but which is supported by an emulator.

One implementation of such an emulator can be found here:
