Subject: [PATCH 0/6] arm64: Add EFI stub and runtime services support
Date: Fri, 10 Jan 2014 17:29:04 -0500 [thread overview]
Message-ID: <1389392950-22457-1-git-send-email-msalter@redhat.com> (raw)
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.
Changes since v1:
* Added Acks (well, one anyway)
* The first 3 patches are new for v2 and provide more generic
support for for following EFI patches.
* Lots of changes based on feedback from Catalin mostly. I think
I addressed all of his comments.
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
This is now in the akpm tree
- early_ioremap support being discussed here:
https://lkml.org/lkml/2014/1/9/708
- shared EFI update_fdt() function in this series:
