The previous version made it necessary to first generate an EDID data set without correct CRC and then to fix the CRC in a second step. This patch adds the CRC calculation to the makefile in such a way that a correct EDID data set is generated in a single build step. Successfully tested with all existing and a couple of new data sets.
