STM32F4Discovery board port.

Fork is using libopencm3 library to access hardware.

Some restrictions to take care of

Size of VM shouldnt be over 16kb, the size of first page where VM will reside. Using what is left of 16kb is complicated, so size up to 16kb should be ok.
Top level for ROM use is 1024KB - 32KB, maybe some additional data/configuration on one of the first pages, that is why -32KB.
Max memory usage up to 192KB, part of that memory is CCM(DMA uncapable) and should be used taken care of accordingly.

D0 - PC8 D1 - PC9 D2 - PC10 D3 - PC11 CLK - PC12 CMD - PD2 CD - PD3
