i.MX5x DCD loading has not worked since the new DCD_WRITE command was added in commit 6deb910dd0a64267c43e65e95486f975e293823f. This prevents the imx_usb_loader from being used on processors like i.MX53.
It appears the DCD_WRITE command is only supported on i.MX6 and later processors. The old method of individually writing each DCD value still needs to be used for the i.MX5x processors.
