ARM: S5PV310: Support ethernet for SMDKV310 and SMDKC210
Browse files Browse the repository at this point in the history 
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
