This enables support for the Mediama RMT1 or RMT2 board.
|

RMT provides LCD support, AC97 codec and other
|
||||
optional peripherals to the Atmel NGW100.
|
||||
|
||||
This choice disables the detect pin and the write-protect pin for the
|
||||
MCI platform device, since it conflicts with the LCD platform device.
