2016-12-15soc/intel/common: remove mrc cache assumptionsAaron Durbin
Update the mrc cache implementation to use region_file. Instead of relying on memory-mapped access and pointer arithmetic use the region_devices and region_file to obtain the latest data associated with the region. This removes the need for the nvm wrapper as the region_devices can be used directly. Thus, the library is more generic and can be extended to work on different boot mediums.

2016-04-08soc/intel/common/nvm: Allow overriding to_flash_offset() functionAlexandru Gagniuc
On apollolake, the flash is memory-mapped differently, and the default MMIO to flash calculation does not produce correct results. While the long-term solution is to rewrite the NVM functionality to keep the flash offset as part of its context, as a temporary measure, allow overriding the to_flash_offset() function by declaring it weak.

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>
2015-04-18soc/intel/common: Add function to protect MRC cacheDuncan Laurie
Add support for applying write protection to the MRC cache region in SPI flash. This is only enabled if there is write protect GPIO that is set, and the flash status register reports that the flash chip is currently write protected. Then it will call out to a SOC specific function that will enable write protection on the RW_MRC_CACHE region of flash. The implementation is not quite as clean as I would like because there is not a common flash protect interface across SOCs so instead it relies on a new Kconfig variable to be set that will indicate a SOC implements the function to protect a region of SPI flash.
