Adds support for Embedtronics Oy's MRFSA board. Board features AT91SAM9G20 controller, 64 MB of SDRAM, two 64 Mbit data flashses (AT45DB321), SD card slot, GSM modem, GPS receiver, ZigBee (CC2420), USB host ports, USB device port, two RS232 and one RS422/RS485 port, two opto isolated inputs, two relays and bunch of leds.
This patch supports booting (e.g. Linux kernel) from following media/interface:
- dataflash - ethernet - debug serial port - SD/MMC
