From 3ef2146262c6f9aff793971d96bab901657469f4 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Tue, 8 Aug 2017 18:27:19 -0700 Subject: 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.
