This is a straightforward conversion of existing tables into X-Macro style definitions for the GPIO alternate functions. This change in itself, is not particularly powerful, but having all GPIO settings in a single file makes a board easier to understand. Signed-off-by: Anton Staaf <robotboy@chromium.org> BRANCH=none TEST=make buildall -j Followed by manual testing of interrupt on change and UART functionality on STM32F0 based discovery board.
