+Subject: [PATCH] mkimage: check environment for dtc binary location
+
+Currently mkimage assumes the dtc binary is in the path and fails
+otherwise. This patch makes it check the DTC environment variable first
+for the dtc binary and then fall back to the default path. This makes
+it possible to call the u-boot build with make DTC=... and build a fit
+image with the dtc binary not being the the default path.
