This patch adds ARM_L1_CACHE_SHIFT_6 into arch/arm/Kconfig. Basically,
ARM L1 cache line size is 32Bytes. Therefore, whenever new ARCH which
has 64Bytes L1 cache line size is added, have to set ARM_L1_CACHE_SHIFT
to 6. That is, have to add/modify arch/arm/mm/Kconfig.
This patch is for handle it in each ARCH such as ARCH_OMAP3, ARCH_S5PC1XX,
and ARCH_S5PV210 which is in review.
This patch also adds selecting ARM_L1_CACHE_SHIFT_6 into Kconfig of
ARCH_OMAP3 and ARCH_S5PC1XX.
