Subject: [PATCH] MdePkg/Uefi ARM: only support native ARM/Thumb images
Date: Fri, 8 Dec 2017 15:55:14 +0000 [thread overview]
Message-ID: <20171208155514.18926-1-ard.biesheuvel@linaro.org> (raw)
The ARM calling convention is fundamentally incompatible with EBC,
and having a cross compatible machine type identical to the native
type does not make a lot of sense either. So restrict the compatible
machine type for ARM to EFI_IMAGE_MACHINE_ARMTHUMB_MIXED, and remove
the cross compatible.
