ARM: S5PV310: Support ethernet for SMDKV310 and SMDKC210
This patch adds to support ethernet for SMDKV310 and SMDKC210 board. - define smc911x resources - define configurations of smc911x platform data - define platform device "smsc911x" - initialize srom controller for lan9215 chip Signed-off-by: Daein Moon <moon9124@samsung.com> Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
