2011-02-22ARM: EXYNOS4: Add EXYNOS4 CPU initialization supportKukjin Kim
This patch adds EXYNOS4 CPU support files in mach-exynos4, and basically they are moved from mach-s5pv310 so that it can support Samsung's new CPU name, EXYNOS4. The EXYNOS4 ingegrates a ARM Cortex A9 multi-core. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2010-12-30ARM: S5PV310: Set bit 22 in the PL310 (cache controller) AuxCtlr registerChanghwan Youn
This patch is applied according to the commit 1a8e41cd672f894bbd74874eac601e6cedf838fb (ARM: 6395/1: VExpress: Set bit 22 in the PL310 (cache controller) AuxCtlr register). Actually, S5PV310 has same cache controller(PL310). Following is from Catalin Marinas' commit. Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption.

2010-12-14ARM: GIC: consolidate gic_cpu_base_addr to common GIC codeRussell King
Every architecture using the GIC has a gic_cpu_base_addr pointer for GIC 0 for their entry assembly code to use to decode the cause of the current interrupt. Move this into the common GIC code.
