2013-05-09ARM: EXYNOS5: Fix kernel dump in AFTR idle modeInderpal Singh1-3/+2
The kernel crashes while resuming from AFTR idle mode. It happens because L2 cache was not going into retention state. This patch configures the USE_RETENTION bit of ARM_L2_OPTION register so that it does not depend on MANUAL_L2RSTDISABLE_CONTROL of ARM_COMMON_OPTION register for L2RSTDISABLE signal.

2011-11-06ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynosKukjin Kim1-0/+230
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has made for plaforms based on EXYNOS4 SoCs. But since upcoming Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most codes in current mach-exynos4, one mach-exynos directory will be used for them. This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos) but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to avoid changing in driver side.
