From 52084bfc8027902e540433be8dea2ce64c8c9f7d Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Fri, 8 Feb 2019 18:42:26 +0100 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.
