# !!! Dirty hack !!!

# All targets which we currently support or have realistic prospects of
# supporting are derived from TI's D-sample and/or Leonardo reference designs.
# TI's voodoo BOARD number for D-sample is 41, and Leonardo apparently
# shared D-sample's number instead of having its own.
# My initial hope was to keep those BOARD conditionals out of our code,
# but they are sprinkled so liberally throughout TI's code that it's
# too much extra work to reshape them into something cleaner.
# So for now let's export a #define BOARD 41 for all targets
# and leave it be.
