Mmc boot

Is it possible to boot Foxboard from sdcard? YES

1. Apply http://www.crisos.org/flyspray/index.php?do=details&task_id=42 patch
2. Edit target/linux/etrax/config-2.6.30 and change kernel commad line with root=/dev/mmc1 rootfstype=ext2,jffs2 rootwait noinitrd console=ttyS0,115200
3. Enjoy!
