From 363288efc5d559b2a97da02a16f796a795af5215 Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Thu, 30 Apr 2020 20:34:11 +0200 Subject: linux-toradex-mainline: allow to build with rt-patch applied With preempt-rt in overrides, the recipe now builds an RT kernel. i.e.: - downloads the rt patch as specified in SRC_URI and applies it - uses the provided defconfig but modifies the configuration to use PREEMPT_RT.
