dde_linux: Support for Raspberry Pi
At the current stage, the USB HID and storage drivers are prinicpally working but not stable. If interrupts are not processed fast enough, devices will get sporadically disconnected. The USB host-controller driver is not part of the normal Linux kernel. For this reason, we need to download it separately. There exists a 'prepare_rpi' rule in the 'dde_linux/Makefile' to automate this process.
