2015-04-13vboot: remove vboot_handoff.h from chromeos.hDaisuke Nojiri
chromeos.h includes vboot_handoff.h, which includes vboot_api.h. since vboot_api.h is not available to non-chromeos projects, build fails for some boards (e.g. glados). this change removes (unnecessary) inclusion of vboot_handoff.h in chromeos.h and fixes other files which rely on indirect inclusion of vboot_handoff.h by making it direct.

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 The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date.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).

2015-03-24vboot2: separate verstage from bootblockDaisuke Nojiri
With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over the bootblock, then exits to the romstage. this is necessary for some SOC (e.g. tegra124) which runs the bootblock on a different architecture. With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock. Then, the bootblock loads the romstage over the verstage and exits to the romstage. this is probably necessary for some SOC (e.g. rockchip) which does not have SRAM big enough to fit the verstage and the romstage at the same time.

2013-03-22romstage: add support for vboot firmware selectionAaron Durbin
This patch implements support for vboot firmware selection. The vboot support is comprised of the following pieces: 1. vboot_loader.c - this file contains the entry point, vboot_verify_firmware(), for romstage to call in order to perform vboot selection. The loader sets up all the data for the wrapper to use. 2. vboot_wrapper.c - this file contains the implementation calling the vboot API. It calls VbInit() and VbSelectFirmware() with the data supplied by the loader. The vboot wrapper is compiled and linked as an rmodule and placed in cbfs as 'fallback/vboot'. It's loaded into memory and relocated just like the way ramstage would be. After being loaded the loader calls into wrapper. When the wrapper sees that a given piece of firmware has been selected it parses firmware component information for a predetermined number of components. Vboot result information is passed to downstream users by way of the vboot_handoff structure. This structure lives in cbmem and contains the shared data, selected firmware, VbInitParams, and parsed firwmare components. During ramstage there are only 2 changes: 1. Copy the shared vboot data from vboot_handoff to the chromeos acpi table. 2. If a firmware selection was made in romstage the boot loader component is used for the payload. Noteable Information: - no vboot path for S3. - assumes that all RW firmware contains a book keeping header for the components that comprise the signed firmware area. - As sanity check there is a limit to the number of firmware components contained in a signed firmware area. That's so that an errant value doesn't cause the size calculation to erroneously read memory it shouldn't. - RO normal path isn't supported. It's assumed that firmware will always load the verified RW on all boots but recovery. - If vboot requests memory to be cleared it is assumed that the boot loader will take care of that by looking at the out flags in VbInitParams. Built and booted. Noted firmware select worked on an image with RW firmware support. Also checked that recovery mode worked as well by choosing the RO path.
