This adds very basic STMicroelectronics MP1 support. No 1st stage so far, only the clock driver and UART driver have been ported. the only supported board right now is the DK2 development board. This is basically a "Let's see how far I can get in a single day" effort. Stay tuned for more, but currently this is more of a low priority project.
