2016-07-28vboot: Separate vboot from chromeosFurquan Shaikh
VBOOT_VERIFY_FIRMWARE should be independent of CHROMEOS. This allows use of verified boot library without having to stick to CHROMEOS.

2016-07-25google/chromeos: Add support for saving recovery reason across rebootFurquan Shaikh
On some x86 platforms (skylake, apollolake), we observe reboots at different steps during the FSP initialization. These additional reboots result in loss of recovery request because vboot_reference library clears recovery request on vbnv once verification is complete and it has made a decision about which boot path to take(normal/dev, slot-a/slot-b, recovery). Provide a way to allow mainboards/chipsets to inform recovery module in vboot2 to save recovery reason to survive unexpected reboots. The recovery reason is set in vbnv after vboot_reference library completes its verification and clears the reason in vbnv while jumping to payload.

2016-07-25vboot: Clean up vboot codeFurquan Shaikh
1. Remove unused functions/structures. 2. Add checks for NULL return values. 3. Change prefixes to vb2 instead of vboot for functions used internally within vboot2/ 4. Get rid of vboot_handoff.h file and move the structure definition to vboot_common.h 5. Rename all functions using handoff structure to have prefix vboot_handoff_*. All the handoff functions can be run _only_ after cbmem is online. 6. Organize vboot_common.h content according to different functionalities.

2015-12-10cbfs/vboot: remove firmware component supportAaron Durbin
The Chrome OS verified boot path supported multiple CBFS instances in the boot media as well as stand-alone assets sitting in each vboot RW slot. Remove the support for the stand-alone assets and always use CBFS accesses as the way to retrieve data. This is implemented by adding a cbfs_locator object which is queried for locating the current CBFS. Additionally, it is also signalled prior to when a program is about to be loaded by coreboot for the subsequent stage/payload. This provides the same opportunity as previous for vboot to hook in and perform its logic. BUG=chromium:445938 BRANCH=None TEST=Built and ran on glados.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-11vboot: prepare for x86 verstageAaron Durbin
In order to support x86 verstage proper the work buffer needs to live in cache-as-ram. However, after cache-as-ram is torn down one still needs the verification results to know which slot was selected. Though the platforms with a dedicated SRAM can just use the work buffer in SRAM, the x86 cache-as-ram platforms need a place to stash the results. For that situation cbmem is employed. This works because when cbmem is initialized cache-as-ram is still enabled. The VBOOT_DYNAMIC_WORK_BUFFER case assumes verified boot doesn't start until after cbmem is up. That doesn't change, but it's a goal to get rid of that option entirely once all other x86 platforms are moved over to pre-romstage vboot. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados with pre-romstage verification as well as VBOOT_DYNAMIC_WORK_BUFFER case.

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>
