Adding Beagleboard support - unfinished
The beagleboard target is still unfinied: running: - MMC Card (incl. boot) - DSS2 graphic driver missing: - full USB Host and Gadget TODO: - improve graphic support - full boot from flash and SD - incl. update - XServer - Gaming support SVN-Revision: 18775v19.07.3_mercusys_ac12_duma
