In systems based on [U]EFI-conformant firmware, runtime services provide
a standardised way for the kernel to update firmware environment
variables. This is used for example by efibootmgr to update which image
should be loaded on next boot.

This patchset implements basic support for UEFI runtime services on ARM
platforms, as well as the basic underlying EFI support. It also defines
a mechanism by which the required information is passed from the
bootloader to the kernel via FDT entries.

This patchset depends on the previously submitted early_ioremap() and
generic UEFI config table scanning patchsets.

Changes from v1:
- Updated FDT bindings, based on feedback.
- Use common config table scanning and address lookup code.
- Add dependency on !CPU_BIG_ENDIAN (for now).
- Add proper efi_enabled() facility.
- Documentation updates.

This series is generally looking sane to me without looking at the
code in very close detail.

Do you have a test setup that you've been using for this that you
could give a pointer to?
