[ARM] 3635/1: S3C24XX: Add S3C2412 core cpu support
Patch from Ben Dooks Add support for the Samsung S3C2412 and S3C2413 range of SoCs. This patch contains the core identification, debug macros, and basic register updates to get these to build. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
