[PATCH 0/3] arm64: Add EFI stub and runtime services support

This patch series adds EFI support to the arm64 kernel. This support has
two main parts: an EFI stub and runtime support. The EFI stub support
has the kernel masquerade as a PE/COFF application which can be directly
booted by EFI firmware (or by secondary loaders with EFI support). The
runtime services support provides access to various EFI firmware services
such as reboot, real-time clock, boot variables, and others.

These patches have dependencies on other patches which are not yet in
the kernel but have been posted and are currently under review. In
particular:

  - Generic fixmap support being discussed here:
      http://lkml.org/lkml/2013/11/25/474

  - early_ioremap support being discussed here:
      https://lkml.org/lkml/2013/11/27/621

  - shared EFI update_fdt() function being discussed here:
      https://lkml.org/lkml/2013/11/27/565
