[ARM] 3588/1: AT91RM9200 CSB337/637 board update
Patch from Andrew Victor This patch updates the support for the Cogent CSB337 and CSB637 boards. The changes include: 1. Use the new at91_uart_config structure and device registration functions for the UARTs. 2. Registration of I2C and SPI platform devices. 3. The CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs. [Patch from David Brownell] Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
