ARM: S3C2416: Add arch support
Add arch/arm/mach-s3c2416 for support of the Samsung S3C2416 SoC. This patch adds support of the S3C2416 SoC, clocks, timers, and initial IRQ support (without support of secondary set of registers). Signed-off-by: Yauhen Kharuzhy <jekhor@gmail.com> [ben-linux@fluff.org: removed files to be reworked, fixed conflicts] [ben-linux@fluff.org: use s3c2443 reset instead of specific reset code] Signed-off-by: Ben Dooks <ben-linux@fluff.org>
