From 4cca498602b0e9831210acb132e3161dab73a87e Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Mon, 22 Oct 2018 23:47:53 +0200 Subject: [PATCH] ipq40xx: rt-ac58u: replace ubi auto load hack This patch replaces the custom autoload quirk of the RT-AC58U with a bootargs-append overwrite. The vendor's u-boot doesn't leave the bootargs / cmdline alone, so the it can't be overwritten in any other way right now... And of course, this will be a lot of fun to deal with once the device switches to the new spi-nand subsystem.
