efi/bgrt: Enable ACPI BGRT handling on arm64
Now that the ACPI BGRT handling code has been made generic, we can enable it for arm64. Signed-off-by: Bhupesh Sharma <bhsharma@redhat.com> [ Updated commit log to reflect that BGRT is only enabled for arm64, and added missing 'return' statement to the dummy acpi_parse_bgrt() function. ] Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Matt Fleming <matt@codeblueprint.co.uk> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-efi@vger.kernel.org Link: http://lkml.kernel.org/r/20170404160245.27812-8-ard.biesheuvel@linaro.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
