hi Haavard,

The platform_data structure is currently defined in
include/asm-arm/arch-at91rm9200/board.h as:

struct at91_uart_data {
short use_dma_tx; /* use transmit DMA? */
short use_dma_rx; /* use receive DMA? */

I don't think the DMA-support is currently in mainline, but is in the
pending patches on

I guess we can just add another field:
short no_remap; /* base address is already mapped */
(or something similar)
