From: Daniel Golle Date: Wed, 31 Mar 2021 20:29:26 +0000 (+0100) Subject: kernel: fix FIT partition parser compatibility issues X-Git-Tag: mikrotik~2438 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aa0adc8e3c2015d28b7cb56e53017a2dc9fda02d;p=openwrt%2Fstaging%2Fchunkeey.git kernel: fix FIT partition parser compatibility issues The uImage.FIT partition parser used to squeeze in FIT partitions in the range where partition editor tools (fdisk and such) expect the regular partition. This is confusing people and tools when adding additional partitions on top of the partition used for OpenWrt's uImage.FIT. Instead of squeezing in the additional partitions, rather start with all uImage.FIT partitions at offset 64.
