# file: fwbin2h
#
# This file converts binary firmware files (e.g. extracted
# from Windows drivers) into a C header file.
#
# invocation:
# fwbin2h <internal fw> <external fw> <radio chipset>
#
# which expects the internal and external firmware part in the
# two files <internal fw> <external fw>.
# please use: <radio chipset> ::= 503rfmd | i3861 | i3863 | 505rfmd
# output will be into the file: fw_<radio chipset>_<version>.h
# where the version is extracted from the internal fw part.
