From e386b279fdab758f75160636bca5385dae202aee Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 6 Jul 2023 20:55:17 +0200 Subject: [PATCH] generic: 6.1: fix uImage.FIT partitions on mtdblock and ubiblock When refreshing the hack patches for Linux 6.1 the part of the uImage.FIT partition parser patch which takes care of allowing mtdblock and ubiblock devices to have partitions has been dropped, supposedly by accident. Re-add a that part to the patch, so devices using a uImage.FIT filesystem sub-image as rootfs can work with Linux 6.1.
