From 43a53891ce8f141e11960bc7b4ad369588ac341d Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Mon, 18 May 2020 12:35:15 +0200 Subject: [PATCH] ipq806x: import bootargs-append from IPQ40xx This imports the patch that adds bootargs-append support from IPQ40xx. This way we can append additional boot arguments from DTS instead of only being able to overwrite them. This way dual firmware devices can use the rootfs number that bootloader passes to decide from what to boot. But we still need to append console info and ubi root info. This is used by Edgecore ECW5410.
