From: Christian Lamparter Date: Mon, 22 Oct 2018 21:47:53 +0000 (+0200) Subject: ipq40xx: rt-ac58u: replace ubi auto load hack X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6840f15a16607a2c08241ae3f8932b5c0431486b;p=openwrt%2Fstaging%2Fnbd.git 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.
