From 81a561b4a64d3d0107e82f49e52d4d0ff1a29719 Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Wed, 5 Jan 2022 00:36:13 +0900 Subject: [PATCH] kernel: move bootargs-append patch to generic This moves bootargs-append support patch from ipq40xx and ipq806x to generic. This way we can append additional boot arguments from DTS instead of only being able to overwrite them. This is a preparation for kirkwood support of ipTIME NAS1.
