From d6d502fa4be1acd01971476fc732c95a4da16d90 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Mon, 22 Feb 2010 00:02:59 +0100 Subject: [PATCH] ARM: 5952/1: ARM: MM: Add ARM_L1_CACHE_SHIFT_6 for handle inside each ARCH Kconfig Add ARM_L1_CACHE_SHIFT_6 to arch/arm/Kconfig to allow CPUs with L1 cache lines which are 64bytes to indicate this without having to alter the arch/arm/mm/Kconfig entry each time. Update the mm Kconfig so that ARM_L1_CACHE_SHIFT default value uses this and change OMAP3 and S5PC1XX to select ARM_L1_CACHE_SHIFT_6.
