2015-05-20acpi: make fill_slit and fill_srat into arguments.Vladimir Serbinenko

2015-05-20build system: use archives, not linker action to shorten command linesPatrick Georgi
Intermediate linking may distort linker behavior (in particular related to weak symbols). The idea is that archives are closer to 'just a list of object files', and ideally makes the linker more predictable. Using --whole-archive, the linker doesn't optimize out object files just because their symbols were already provided by weak versions. However it shouldn't be used for libgcc, because that one has some unexpected side-effects.

2015-05-19arm64: Make SPSR exception masking on EL2 transition explicitJulius Werner
The configuration of SPSR bits that mask processor exceptions is kinda oddly hidden as an implict part of the transition() function right now. It would be odd but not impossible for programs to want to be entered with enabled exceptions, so let's move these bits to be explicitly set by the caller like the rest of SPSR instead. Also clear up some macro names. The SPSR[I] bit is currently defined as SPSR_IRQ_ENABLE, which is particularly unfortunate since that bit actually *disables* (masks) interrupts. The fact that there is an additional SPSR_IRQ_MASK definition with the same value but a different purpose doesn't really help. There's rarely a point to have all three of xxx_SHIFT, xxx_MASK and xxx_VALUE macros for single-bit fields, so simplify this to a single definition per bit. (Other macros in lib_helpers.h should probably also be overhauled to conform, but I want to wait and see how many of them really stay relevant after upcoming changes first.)

2015-05-19arm64: Add support for using ARM Trusted Firmware as secure monitorJulius Werner
This patch adds support for integrating the runtime-resident component of ARM Trusted Firmware (github.com/ARM-software/arm-trusted-firmware) called BL31. It expects the ARM TF source tree to be checked out under $(top)/3rdparty/arm-trusted-firmware, which will be set up in a later patch. Also include optional support for VBOOT2 verification (pretty hacky for now, since CBFSv1 is just around the corner and will make all this so much better).

Rename Kconfig options for secmon and spintable to be prefixed with ARM64_ instead of ARCH_, which seems to be the standard throughout the rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this provides a clearer separation between generic options that are selected by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to some of the MAINBOARD_HAS_... we have) and options that only make sense in the context of a single architecture.

2015-04-21arch/mips: simplify cache operationsIonela Voinescu
Cache operations are simplified by removing assembly implementation and replacing it with simpler C code. BUG=chrome-os-partner:31438 TEST=tested on Pistachio bring up board; caches are properly invalidated; BRANCH=none Change-Id: I0f092660549c368e98c208ae0c991fe6f5a428d7 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: bf99849e75813cba865b15af9e110687816e61e4 Original-Change-Id: I965e7929718424f92f3556369d36a18ef67aa0d0 Original-Signed-off-by: Ionela Voinescu <ionela.voinescu@imgtec.com> Original-Reviewed-on: https://chromium-review.googlesource.com/250792 Original-Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-on: http://review.coreboot.org/9820 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2015-04-21urara: Identity map DRAM/SRAMAndrew Bresticker
Using identity_map(), map the DRAM/SRAM regions to themselves (which happens to be using KUSEG on urara). The bootblock (which still runs in KSEG0) sets up the identity mapping in bootblock_mmu_init() so that ROM/RAM stages can be loaded into the KUSEG address range. The stack and pre-RAM CBMEM console also remain in KSEG0 since we don't really care about their physical addresses. Also splitting CBFS cache to pre and post RAM, to allow for larger rambase images. BUG=chrome-os-partner:36258 BRANCH=none TEST=With the rest of coreboot and depthcharge patches applied: - booted urara into the kernel login prompt - from depthcharge CLI tried accessing memory below 0x100000 - observed the exception.
