Subject: [PATCH 1/4] This patch adds ok2440 development board support.
The ok2440 development board is based on SAMSUNG's S3C2440
microprocessor,which is developed with ARM920T core.
The file is modified from arch/arm/mach-s3c2440/mach-smdk2440.c
that maintained by Ben Dooks <ben@...tec.co.uk>
I modified it to fit the ok2440 development board.
The following patches are against v3.0-rc2.
