Subject: [PATCH] colibri_imx6: use SDP if USB serial downloader has been used
In case USB serial downloader has been used to load U-Boot start the
serial download protocol (SDP) emulation. This allows to download
complete images such as Toradex Easy Installer over USB SDP as well.
This code uses the boot ROM provided boot information to reliably
detect USB serial downloader.
