[ARM] 4109/2: Add support for the RealView/EB MPCore revC platform The kernel originally supported revB only. This patch enables revC by default and adds a config option for building the kernel for the revB platform. Since the SCU base address was hard-coded in the proc-v6.S file (and only valid for RealView/EB revB), this patch also adds a more generic support for defining the SCU information.

ARM: pm: add function to set WFI low-power mode for SMP CPUs Add a function to set the SCU low-power mode for SMP CPUs. This centralizes this functionality rather than having to expose the SCU register definitions to each platform. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
