[ARM] 4478/1: AT91: Convert AT91RM9200 to use atmel_spi driver
Browse files Browse the repository at this point in the history
Convert the AT91RM9200 platform-setup code to use the new atmel_spi
driver (and manually-driven chip-selects), instead of the legacy
AT91-only SPI stack.

The AT91SAM9 processors are already using the atmel_spi driver.
