2013-05-13staging: add mausezahn staging directoryDaniel Borkmann1-0/+888
After some back and forth, we decided that it is easier to maintain mausezahn in a staging directory until it is fully reworked and cleaned up to be ready to be fully integrated. This way, it is better than having it in a separate branch, and we can also accept patches from outside more easily. Also, while at it, fix up some function mismatches with libcli.

spi: add driver for J-Core SPI controller
The J-Core "spi2" device is a PIO-based SPI master controller. It differs from "bitbang" devices in that that it's clocked in hardware rather than via soft clock modulation over gpio, and performs byte-at-a-time transfers between the cpu and SPI controller. This driver will be extended to support future versions of the J-Core SPI controller with DMA transfers when they become available.
