From 0e29e05deed1edd3884ca888ae7e1b549c84bfd0 Mon Sep 17 00:00:00 2001 From: Pawel Dembicki Date: Thu, 24 Jun 2021 13:10:09 +0200 Subject: [PATCH] kirkwood: increase kernel partition of Linksyses At this moment kernel partition in Linksyses EA3500/E4200/EA4500 is ended before start of rootfs partition. It was introduced in 9808b9ae02 and it broke easy revert to stock. Sysupgrade, when OFW is used, write whole stock image to kernel partition. Most likeley image will be bigger than small kernel partition and it make stock system invalid. This patch change size of kernel partitions and now it overlaps rootfs. Revert to stock will be possible again.
