Patches 5 to 7, replace "[PATCH-ARM 2/2] Add support for the Embest SBC2440-II Board 2/2" submitted on 19/06/2009.

This patch adds support for the s3c2440 cpu, excluding the NAND driver which is in patch 6/7.

This patch assume the following patches have already been applied:

- [PATCH-ARM] Bug-fix in drivers mtd nand Makefile, sent 18/06/2009 - [PATCH-ARM] CONFIG_SYS_HZ fix for ARM920T S3C24X0 Boards, sent 21/06/2009

The patch was tested by running MAKEALL for all ARM9 targets and checking that no new warnings or errors were introduced.
