ec6c8dcda1 Always enable USB serial port for reset 
To allow for uploads when sketches don't manually start the Serial port,
start the USB port always in main().

b2cef8d8d6 Adafruit Feather, overclocking, flash FS shims 
Add support for Adafruit Feather RP2040 (8MB).  Identified with a unique
USB PID so it displays properly once programmed one time.  Moved LED to
pin 13 (per the website docs), but have no board to test.

Add over/underclocking menus, applied at boot.  Use at your own risk, as
usual.

Add shims to allocate flash space for a filesystem (but not implemented
yet).

Add a "generic" RP2040 board

4076bf85ab Fix INPUT_PULLUP/DOWN, I2C 0-len probes, timeout 
Fix the drive logic for pullup and pulldown inputs.

Add a bitbanged I2C ACK checker for 0-byte I2C transfers (since the HW
doesn't support it).

Add a timeout on I2C reads and writes so they don't hang forever if a
device is not present.

when in a multicore sketch.

b96c37164e Fix attachInterrupt to handle single GPIO callback 
The Pico SDK only supports a single callback pointer for all GPIO
interrupt pins.  So we need to track the individual pin-to-CB map
ourselves and dispatch from our own internal callback routine.

b463825374 Rationalize pin selection using readable template

hardware.  This lets us have an easily readable list of pin numbers that
