From 2acf355e56fa099bbd4ac881aed642b8df6022e7 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sat, 30 Apr 2022 15:14:01 +0100 Subject: [PATCH] kernel: don't parse FIT partition on NAND-backed mtdblock ubiblock devices should be used on NAND flash to store the uImage.FIT in case the bootloader supports that -- otherwise only rootfs is stored in UBI while the uImage.FIT contains only the kernel and dtb. Hence there is no need to enable parsing partitions on NAND mtdblock devices, it is even responsible for the ugly warning on-opening of the mtdblock device now. Just don't do it.
