	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>
2015-04-27	arm64: save/restore cptr_el3 and cpacr_el1 registers	Joseph Lo
	CPTR_EL3 and CPACR_EL1 are the registers for controlling the trap level and access right of the FPU/SIMD instructions. Need to save/restore them in every power cycle to keep the settings consistent.

2015-04-22	arm64: save and restore cntfrq for secondary cpus	Jimmy Huang
	CNTFRQ_EL0 can only be set in highest implemented exception level. Save and restore CNTFRQ_EL0 for secondary cpus in coreboot. This patch fix the error below: SANITY CHECK: Unexpected variation in cntfrq. Boot CPU: 0x00000000c65d40, CPU1: 0x00000000000000 BRANCH=none BUG=none TEST=boot to kernel on oak board and check secondary cpu's cntfrq. confirmed cpu1's cntfrq is same as boot cpu's.

2015-04-10	arm64: Add support for save/restore registers for CPU startup.	Furquan Shaikh
	startup.c provides function to enable CPU in any stage to save register data that can be used by secondary CPU (for normal boot) or any CPU (for resume boot). stage_entry.S defines space for saving arm64_startup_data. This can be filled by: 1) Primary CPU before bringing up secondary CPUs so that the secondary can use register values to initialize MMU-related and other required registers to appropriate values. 2) CPU suspend path to ensure that on resume the values which were saved are restored appropriately. stage_entry.S provides a common path for both normal and resume boot to initialize saved registers. For resume path, it is important to set the secondary entry point for startup since x26 needs to be 1 for enabling MMU and cache. This also ensures that we do not fall into false memory cache errors which caused CPU to fail during normal / resume boot. Thus, we can get rid of the stack cache invalidate for secondary CPUs. BUG=chrome-os-partner:33962 BRANCH=None TEST=Compiles and boots both CPU0 and CPU1 on ryu without mmu_enable and stack cache invalidate for CPU1.
