Currently the Serial Download Protocol tools and procedure are documented in two places:
- doc/imx/README.sdp - doc/imx/README.imx6
It is better to consolidate all SDP related information into README.sdp file, so move the content from README.imx6 to README.sdp.

Also the U-Boot side support beside the i.MX specific header the U-Boot legacy header.
