ARM: S3C64XX: Initial support for Wolfson/Simtec Cragganmore/Banff
The Cragganmore carrier card and Banff CPU module are used on Wolfson Microelectronics reference systems. This initial support covers the core system which is a fairly generic S3C6410 based design, further patches will add support for the key features of the reference system. The initial board bringup and therefore much of the key code was done by Ben Dooks for Simtec, with additional work (especially around the integration of the Wolfson devices) being done by myself. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> [kgene.kim@samsung.com: removed inclusion of <mach/regs-fb.h>] Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
