config BOARD_ATNGW100_MRMT

	bool "Mediama RMT1/2 add-on board"

	help

	  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.

	  The MCI pins can be reenabled by editing the "add device function" but

	  this may break the setup for other displays that use these pins.
