2016-02-09chromeos: Add option to back up VBNV CMOS into flashDuncan Laurie
This adds a new kconfig option that will back up the VBNV data from CMOS to flash, and restore it if the CMOS data is invalid during boot. This allows special flags to not get lost when power is lost, RTC reset is triggered, or CMOS is corrupted.

2016-02-09chromeos: Remove CONFIG_VBNV_SIZE variableDuncan Laurie
The VBNV region size is determined by vboot and is not really configurable. Only the CMOS implementation defined this config variable so switch it to use VBNV_BLOCK_SIZE defined by vboot in vbnv_layout.h instead. This requires updating the broadwell/skylake cmos reset functions to use the right constant.

2016-02-09chromeos: Add vbnv wrapper for the different backendsDuncan Laurie
Add a wrapper around the vbnv implementations and call into the different backend functions from there. Also move some of the common functions to the common code and simplify the backend drivers. This will allow some of the code to be re-used so the CMOS backend can backup the data into the flash backend. One side effect of this is that the cache of VBNV was removed from CMOS and EC backends and moved into the VBNV wrapper, but the flash backend also still has a separate cache because it has more state and complexity in the implementation. The wrapper cached data is not used for normal vbnv_read/vbnv_write because some callers need the ability to force a write if the backend storage is cleared (i.e. CMOS clear).

2016-01-17intel/skylake: During RO mode after FSP reset CB lose original stateSubrata Banik
CB used to clear recovery status towards romstage end after FSP memory init. Later inside FSP silicon init due to HSIO CRC mismatch it will request for an additional reset.On next boot system resume in dev mode rather than recovery because lost its original state due to FSP silicon init reset. Hence an additional 1 reset require to identify original state. With this patch, we will get future platform reset info during romstage and restore back recovery request flag so, in next boot CB can maintain its original status and avoid 1 extra reboot.

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.

2015-05-21Remove 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>

2015-03-24vboot: Add support for OPROM_MATTERS and SLOW_ECDuncan Laurie
In order to display a "update in progress" screen on devices with a slow EC or PD chip it may be necessary to also load the VGA Option ROM when doing EC software sync. This adds config options for VBOOT_EC_SLOW_UPDATE which simply sets a flag in the input parameters that is already handled by vboot. It also adds a config option for VBOOT_OPROM_MATTERS which is a bit more tricky in that it sets a flag in input parameters, but also needs to keep track of the option rom being loaded and pass that flag into VbInit as well. Since VbInit will clear the NV bit for option rom loaded the check that is done in vboot_wants_oprom() needs to first compare against the vboot handoff copy of the input flags. BUG=chrome-os-partner:32379 BRANCH=samus TEST=manual testing: 1) in normal mode, with EC/PD in RW, ensure that they are rebooted to RO and the VGA Option ROM is loaded and the wait screen is displayed, and then the system is rebooted at the end and the VGA Option ROM is not loaded. 2) same as #1 with EC/PD in RO already, same result 3) same as #1 with system in developer mode, same result except there is no reboot at the end of software sync 4) same as #1 with system in developer mode and EC/PD in RO, ensure that there is no extra reboot at the beginning or end of software sync.

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.
