- support Armbian
+Date: Mon, 26 Nov 2018 19:07:49 +0800
+Subject: [PATCH] helios4: add boot-marvell.cmd backward compatibility
 
-Armbian boot script use different env variable name to load armbianEnv.txt
-and device tree
+On system that still use boot.scr derived from boot-marvell.cmd, new
+u-boot 2018 will failed load dtb and script due to missing some
+variables. This will render the system unbootable.
+
+These changes added the missing variables.
