Date: Wed, 5 Feb 2014 17:03:51 +0000 From: Leif Lindholm <leif.lindholm@...aro.org> To: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-efi@...r.kernel.org Cc: patches@...aro.org, Leif Lindholm <leif.lindholm@...aro.org> Subject: [PATCH 00/22] arm/arm64: UEFI stubs + runtime services This is a combined set of patches for the arm and arm64 kernel support for UEFI firmware. The set depends on the following prerequisite sets: - Laura Abbott's 'Remove ARM meminfo' - Matt Fleming's 'Move facility flags to struct efi' - Mark Salter's 'Generic fixmap' - Mark Salter's 'Generic early_ioremap' - Mark Salter's 'EFI memory map iteration helper' All of these are held on top of 3.14-rc1, with the patches in this set, in git://git.linaro.org/people/leif.lindholm/linux.git, rebasing branch uefi-for-upstream. New in this version: - Much more stub code shared arm/arm64. - Stub looks in configuration tables for DT. - Stub creates empty DT if none found/specified. - Stub ignores dtb= option when UEFI Secure Boot active. - Stub deletes any memory nodes in DT. - Kernel sets up available RAM for memblock from UEFI memory map. (So no longer need different DTs or command line parameters for otherwise identical platforms with different amounts of RAM.) - arm64 now compatible with 64K pages (with 4K UEFI page size). - Fix mapping of runtime mmio regions on arm64. - Reworked update_sctlr asm macro. - Various cleanup and style fixes. --- Ard Biesheuvel (1): arm: efistub: ignore dtb= when UEFI SecureBoot is enabled H.
