This patch, and the others associated with adding the SBC2440-II Board,
have been replaced by the series of patches "Add support for Embest
SBC2440-II Board" 1 to 7. Patches 1 to 3 use lower case for var and type
name, and replace typedef struct by struct, but they still have the
function name as S3C24X0_GetBase_GPIO() instead of s3c24x0_getbase_gpio().
I'm happy to make the function name lower case and re-issue the "Add
support for Embest SBC2440-II Board" patches 1 to 7 but it might be better
if I waited for you to review them first in case you have any other
comments.
Also, these patches rely on one other patch that hasn't been reviewed yet -
"[U-Boot] [PATCH-ARM] CONFIG_SYS_HZ fix for ARM920T S3C24X0 Boards".
