Progress with NuttX

Hi list, with a bit of help from Harald, I finally managed to push my commits. Hence, we have: - platform support for Calypso (timers, irq, ...) - char device driver for keypad (/dev/keypad) - some hacks reusing old drivers for SPI/poweroff and sercomm The console currently outputs in osmocon while you have to write to the loader interface with a python script. Flushing is kind of a problem too. Haven't checked how to fix those two, so any volunteers? Bye, Stefan
