2016-11-18google/chromeec: Add common infrastructure for boot-mode switchesFurquan Shaikh
Instead of defining the same functions for reading/clearing boot-mode switches from EC in every mainboard, add a common infrastructure to enable common functions for handling boot-mode switches if GOOGLE_CHROMEEC is being used. Only boards that were not moved to this new infrastructure are those that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific mechanism for reading boot-mode switches. BUG=None BRANCH=None TEST=abuild compiles all boards successfully with and without ChromeOS option.

2015-09-29chromeos: vboot-related functions move to common vboot codePaul Kocialkowski
This moves a few vboot-prefixed functions that were defined in chromeos.c to vboot_common.c, since those are only relevant to vboot and depend on the vboot handoff data. This allows more separation between CONFIG_CHROMEOS and what CONFIG_CHROMEOS selects, so that each separate option (such as CONFIG_VBOOT_VERIFY_FIRMWARE) can be enabled separately. Thus, the actual definitions of these functions will only be declared when CONFIG_VBOOT_VERIFY_FIRMWARE is set, so the check before calling vboot_skip_display_init in bootmode was also adapted.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

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.

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.

2012-04-02Add Google ChromeOS vendor supportStefan Reinauer
Google's ChromeOS can be booted super fast and safely using coreboot. This adds the ChromeOS specific code that is required by all ChromeBooks to do this.
