2015-04-08Makefile.inc: Only add `-Wno-unused-but-set-variable` for GCCPaul Menzel
Clang (3.5) does not know that option. error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'? [-Werror,-Wunknown-warning-option] Fix up commit f69a99db (coreboot: x86: enable gc-sections) to only add that option, when GCC is used.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

2015-04-06Add predefined __ROMSTAGE__ and __RAMSTAGE__ macrosJulius Werner
This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get predefined in their respective stages by make, so that we have one specific macro for every stage. It also renames __BOOT_BLOCK__ and __VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency. This change is intended to provide finer control and clearer communication of intent after we added a new (optional) stage that falls under __PRE_RAM__, and will hopefully provide some robustness for the future (we don't want to end up always checking for romstage with #if defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) && !defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The __PRE_RAM__ macro stays as it is since many features do in fact need to differentiate on whether RAM is available. (Some also depend on whether RAM is available at the end of a stage, in which case #if !defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be authoritative.) It's unfeasable to change all existing occurences of __PRE_RAM__ that would be better described with __ROMSTAGE__, so this patch only demonstratively changes a few obvious ones in core code. BUG=None TEST=None (tested together with dependent patch).

2015-01-27vboot2: add verstageStefan Reinauer
This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e and fixes the build issue that cuased it to be reverted. Verstage will host vboot2 for firmware verification. It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.
