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: http://news.gmane.org/gmane.linux.kernel.efi A repo with this patch series and the prerequisite patches is at: git://github.com/mosalter/linux.git (arm64-efi-patches-v2 branch) Mark Salter (6): efi: create memory map iteration helper arm64: Add function to create identity mappings efi: add helper function to get UEFI params from FDT arm64: add EFI stub doc: arm64: add description of EFI stub support arm64: add EFI runtime services Documentation/arm64/booting.txt | 4 + Documentation/efi-stub.txt | 12 +- arch/arm64/Kconfig | 26 +++ arch/arm64/include/asm/efi.h | 12 ++ arch/arm64/include/asm/mmu.h | 1 + arch/arm64/kernel/Makefile | 4 + arch/arm64/kernel/efi-entry.S | 93 +++++++++++ arch/arm64/kernel/efi-stub.c | 181 ++++++++++++++++++++ arch/arm64/kernel/efi.c | 353 ++++++++++++++++++++++++++++++++++++++++ arch/arm64/kernel/head.S | 112 +++++++++++++ arch/arm64/kernel/setup.c | 6 + arch/arm64/mm/mmu.c | 34 ++-- drivers/firmware/efi/Kconfig | 7 + drivers/firmware/efi/efi.c | 79 +++++++++ include/linux/efi.h | 17 +- 15 files changed, 927 insertions(+), 14 deletions(-) create mode 100644 arch/arm64/include/asm/efi.h create mode 100644 arch/arm64/kernel/efi-entry.S create mode 100644 arch/arm64/kernel/efi-stub.c create mode 100644 arch/arm64/kernel/efi.c -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
