[ARM] 2889/1: S3C2410 - Add machine Anubis
Patch from Ben Dooks Add the Simtec Anubis to the list of supported machines in the arch/arm/mach-s3c2410 directory. This ensures the core peripherals are registered, the timer source is configured and the correct power-management is enabled. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
