The STM32F76x is really close to the STM32F4 family, so the most concise implementation is just using CHIP_FAMILY_STM32F4 and adding CHIP_VARIANT_F76X. Tune the clock settings to 180 Mhz CPU clock as the goal is performance. (over-drive is not implemented yet to get to 216 Mhz) Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BRANCH=none BUG=none TEST=ran on nucleo-f767zi board. 'make BOARD=nucleo-f767 flash', the red LED is on and the green LED turns on/off when pressing the user button, UART console works properly.
