[ARM] 5289/1: [AT91] Convert boards to use sam9_smc_configure()
Convert the SAM9 and CAP9 board-specific files to make use of the sam9_smc_configure() method to configure the memory-controller for external peripherals. The following boards have been modified: cam60 : NAND cap9adk : NAND, NOR qil-a9260 : NAND sam9-l9260 : NAND sam9260ek : NAND sam9261ek : DM9000 Ethernet, NAND sam9263 : NAND sam9g20ek : NAND sam9rlek : NAND usb-a9260 : NAND usb-a9263 .: NAND Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
