From 29ca10e537ee807283cfd8a58817270d233a021d Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Mon, 19 Oct 2020 15:37:54 +0200 Subject: ipq806x: remove support for kernel 4.19 The target uses 5.4 as default kernel since 04/2020. Kernel 4.19 support is not really maintained anymore, and there has been a lot of changes between 4.19 and 5.4 on this target. Despite, new devices are typically added for 5.4 only anyway. Thus, make maintaining of old stuff and reviewing of new stuff easier by removing support for kernel 4.19.
