Added a new repo for the Toughpad containing a basic run-script

This run-script starts the hello example but write the output to
log files using th rump/ext2 FS driver.
Workaround: Add an offset to the frambuffer base address to allow for graphic output on toughpad

For an unknwon reason the actual framebuffer on the toughpad is shifted
in memory by the size of one frame. Solution: add this offset to the
physical address reported by the BIOS before mapping it to a virtual
address.
NOVA: experimental vga support for console

Can be used for debugging if no serial interface is available.
fix: _map_page changed to _map_pages in master
