Clean-up of cpu_arm920t and cpu_arm920t_s3c24x0 code
This patch re-formats the code in cpu/arm920t and cpu/arm920t/23c24x0 in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, ran MAKEALL for all ARM9 targets and no new warnings or errors were found. Signed-off-by: Kevin Morfitt <kevin.morfitt@fearnside-systems.co.uk> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
