From a48e5bea12911da1647a499a7b74c2408a04ac90 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Sat, 21 Oct 2017 14:51:14 +0300 Subject: [PATCH] brcm2708: restore /boot/config.txt before reboot The Raspberry Pi bootloader reads configuration values from config.txt in the boot partition. This file allows to specify the amount of memory to assign to the GPU, the license keys for hardware MPEG-2 and VC-1 decoding, Device Tree parameters and overlays, and lots of other things. Since sysupgrade only restores the configuration after booting the newly flashed image, these values will not be active, even if sysupgrade would save /boot/config.txt. To solve this, add the file to the files to be backed up, and restore it in platform_copy_config, before reboot.
