Merge tag 'arm32-efi-for-v4.5' of git://git.linaro.org/people/ard.biesheuvel/linux-arm into devel-stable
This implements UEFI kernel support for 32-bit ARM, based on the existing arm64 support and existing generic early ioremap support. It is based on commit f7d924894265 ("arm64/efi: refactor EFI init and runtime code for reuse by 32-bit ARM"), which was pulled from the arm64 repo [1] as branch 'aarch64/efi' [1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git
