Add Serial Download Protocol support (SDP), which allows loading SPL and u-boot.img via imx_usb_loader tool as explained in doc/README.sdp.
Signed-off-by: Fabio Estevam fabio.estevam@nxp.com --- In order to get SDP functional on sabresd we need these two patches from Stefan:
imx: add macro to detect whether USB has been initialized imx_common: detect USB serial downloader reliably
