From 9691b89fd8a0014b7d57c9fc35cf75bfe8da1577 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 3 Nov 2017 15:29:15 -0400 Subject: Rework Linux Kernel fragment applications MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - All kernel recipes must inherit linux-agl.inc - All kernel recipes for a given version (e.g. 4.9) should include linux-VER-agl.inc in order to avoid duplication (such as the SMACK label patch or security fixes) - We enforce having merge_config.sh be invoked at the end, in order to make sure fragments will be applied. - Add a new fragment for Raspberry Pi to ensure the Pi Touchscreen is still enabled. With all of the above, we fix a number of minor issues as well, such as platforms manually enabling NBD/RAMDISK for netboot as the previous logic was not working in all cases.
