Could you please provide more versatile mapping system. E.g. on db845c modem.mbn tries to tqftp following image names:
/readonly/vendor/firmware_mnt/image/wlanmdsp.mbn
/readonly/vendor/firmware/wlanmdsp.mbn
It would be nice to be able to map such paths depending on the command line attributes, so that we can adapt tqftpserver to provide these paths.
