SAMSUNG: SMDKC100: Adds ethernet support.
Add setup for ethernet on SMDKC100, allowing kernel/ramdisk to be loaded over tftp. The preinit function will configure GPIO (GPK0CON) & SROMC to look for environment in SROM Bank 3. Signed-off-by: Naveen Krishna Ch <ch.naveen@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
