automatic update from FIT image: add optional address parameter
Current update_tftp() flow: 1.) fetch "updatefile" from defined TFTP server 2.) check if FIT format 3.) flash contained images Add an address parameter to update_tftp(). If this address is non-zero, skip the TFTP transfer and use the image at this address. Also extend update_tftp() to return success/fail. Signed-off-by: Andreas Pretzsch <apr@cn-eng.de>
