Add generic support for samsung s3c2440
This patch adds generic support for the Samsung s3c2440 processor. Global s3c24x0 changes to struct members converting from upper case to lower case. Signed-off-by: Craig Nauman <cnauman@diagraph.com> Cc: kevin.morfitt@fearnside-systems.co.uk Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
