From 08f95e83e42a0b566d6146d5e999113fca5a6dc8 Mon Sep 17 00:00:00 2001 From: Roland Reinl Date: Sat, 30 Mar 2024 17:59:14 +0100 Subject: [PATCH] mediatek: Moved recovery image creation to include/image-commands.mk The recovery image is reqired for D-Link M30 as well. So I moved it to include/image-commands.mk to be able to use it for MT7622 and filogic devices.
