'''Catch-all module for miscellaneous devices which can't use a
generic or widely used tool like J-Link, OpenOCD, etc.

Please use this sparingly and only when your setup is exotic and
you're willing to handle requests for help. E.g. if your "board" is a
core on a special-purpose SoC which requires a complicated script to
network boot.'''
