circuitpython/ports/esp32s2/Makefile
Jeff Epler 7bb196b9d2 esp32s2: 'make flash': Allow customizing the esptool flags 
This can be useful so that e.g., on a Kaluga when programming via
the FTDI chip, you can override the variable to specify "--after=hard_reset"
to automatically return to running CircuitPython, choose a different
baud rate (921600 is about 2s faster than 460800), etc:
    make BOARD=espressif_kaluga_1 ESPTOOL_FLAGS="-b 921600 --before=default_reset --after=hard_reset"
