2014-12-09vboot: allow for non-memory-mapped VBOOT regionsAaron Durbin
Depending on the platform the underlying regions vboot requires may not be accessible through a memory-mapped interface. Allow for non-memory-mapped regions by providing a region request abstraction. There is then only a few touch points in the code to provide compile-time decision making no how to obtain a region. For the vblocks a temporary area is allocated from cbmem. They are then read from the SPI into the temporarily buffer. BUG=chrome-os-partner:27094 BRANCH=None TEST=Built and booted a rambi with vboot verification.

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.

2014-08-13chromeos: On ARM platforms VBNV lives in the ECStefan Reinauer
This patch renames the x86 way of doing things to explicitly mention CMOS (which is not available on our ARM platforms) and adds an implementation to get VBNV through the Chrome EC. We might want to refine this further in the future to allow VBNV in the EC even on x86 platforms. Will be fixed when that appears. Also, not all ARM platforms running ChromeOS might use the Google EC in the future, in which case this code will need additional work.

2014-08-11coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class. Also, compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.

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.

2012-11-12Avoid using hardcoded values in MRC cache codeVadim Bendebury
The MRC cache code, as implemented, in some cases uses configuration settings for MRC cache region, and in some cases - the values read from FMAP. These do not necessarily match, the code should use FMAP across the board. This change also refactors mrccache.c to limit number of iterations through the cache area and number of fmap area searches.

2012-11-08ELOG: Find flash base in FMAP if possibleDuncan Laurie
Now that we have FMAP support in coreboot use it to find the offset in flash for ELOG to use. If coreboot has elog configured with a smaller size then use that over the FMAP size. This is because I set aside a 16KB region in the FMAP but we only use 4KB of it to keep the impact to boot/resume speed to a minimum. FMAP: Found "FMAP" version 1.0 at ffe10000. FMAP: base = 0 size = 800000 #areas = 32 FMAP: area RW_ELOG found FMAP: offset: 3f0000 FMAP: size: 16384 bytes FMAP: No valid base address, using 0xff800000 ELOG: base=0x003f0000 base_ptr=0xffbf0000 ELOG: MEM @0x00190ad8 FLASH @0xffbf0000 ELOG: areas are 4096 bytes, full threshold 3072, shrink size 1024 Change-Id: I3d826812c0f259d61f41b42797c58dd179f9f1c8 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1706 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-07SandyBridge/IvyBridge: Use flash map to find MRC cacheStefan Reinauer
Until now, the MRC cache position and size was hard coded in Kconfig. However, on ChromeOS devices, it should be determined by reading the FMAP. This patch provides a minimalistic FMAP parser (libflashmap was too complex and OS centered) to allow reading the in-ROM flash map and look for sections. This will also be needed on some partner devices where coreboot will have to find the VPD in order to set up the device's mac address correctly. The MRC cache implementation demonstrates how to use the FMAP parser.

2012-07-26ELOG: Fix reporting of developer/recovery modesDuncan Laurie
Recent changes in EC/Vboot/U-boot have completely broken the logging of developer and recovery modes. Recovery mode may not be in VBNV, so if that is zero and yet we are in recovery mode then assume it is there because the button/key was pressed. Since there may not be any actual developer mode switch we look if option rom is loaded and the system is not in recovery mode and consider that as developer mode.

2012-07-25chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared DataStefan Reinauer
coreboot used to pass some information to u-boot in the coreboot table and other information in a modified flat device tree. Since the FDT code was never upstreamed and removed from our tree, u-boot was changed to get the information it needs from the coreboot table alone. However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data. This patch passes on the ChromeOS specific ACPI data structure instead of the vboot shared data. Another change to u-boot will teach it how to get to the vboot shared data from there.

Originally, on ChromeBooks, coreboot would provide a modified u-boot device tree (FDT) to u-boot in CBMEM. However, u-boot can now create all the information it needs from the coreboot table and add it to its device tree itself. This means we can drop this (anyways unused) code.
