# This script takes the ASCII results from OpenOCD's mdw/mdh/mdb commands and converts it
# to a binary image. The address location is stripped from each line before conversion.
# No attempt is made to fill or otherwise handle non-contiguous memory regions.
#
# Usage: ./ocd_bin.sh file_in file_out
#
# Example input:
# 0x00000000: 2e2f3031 3233343536 3738394142 4344454647 48494a4b4c 4d4e4f50 51525354
