This commit also introduces board directories and moves board specific config into the appropriate board directory. boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet and hand-tweaked. make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c, and boards/BOARD-NAME/pins.csv as input and generates the file build/pins_BOARD_NAME.c The generated pin file for PYBOARD4 looks like this: https://gist.github.com/dhylands/9063231 The generated pins file includes all of the supported alternate functions, and includes upsupported alternate functions as comments. See the commnet block at the top of stm/pin_map.c for details on how to use the pin mapper. I also went ahead and modified stm/gpio.c to use the pin mapper.
