All in-tree boards that use this controller have CONFIG_NET_MULTI added Also: - changed CONFIG_DRIVER_CS8900 to CONFIG_CS8900 - changed CS8900_BASE to CONFIG_CS8900_BASE - changed CS8900_BUS?? to CONFIG_CS8900_BUS?? - cleaned up line lengths - modified VCMA9 command function that accesses the device - removed MAC address initialization from lib_arm/board.c Signed-off-by: Ben Warren <biggerbadderben@gmail.com> Tested-by: Wolfgang Denk <wd@denx.de> Acked-by: Wolfgang Denk <wd@denx.de>
