Linux 3.13 To Support EFI On ARM
While EFI was originally developed by Intel and largely targeting x86 platforms, the EFI 2.3 specification does exist for Itanium and ARM architectures too and early this year the UEFI Forum had shown a proof-of-concept UEFI boot environment for ARMv8. With the EFI pull for the Linux 3.13 merge window, the Linux EFI support extends to ARM.
The EFI ARM support was generalizing x86 and ARM platform differences and cleaning up the code for handling future ARM EFI-based platforms. Other EFI changes for Linux 3.13 include early printk support using the EFI frame-buffer for debugging boot problems, EFI stub support for large memory maps (128+ entires), and other fixes.
More details on these EFI changes can be found via the mailing list pull request.
