While helping with review and build testing of a few 4.19 pull requests, I've noticed, that dtc compiler in OpenWrt uses different options then upstream kernel, which is leading to a very noisy output[1]. It wouldn't be that bad per se, but a lot of such warnings aren't easily fixable so I think, that we should follow what upstream does and simply ignore^W silence those noisy warnings. So this patch tries to syncs dtc compiler flags with upstream kernel till version 4.19.13, disabling those warnings as they were added in upstream kernel: v4.6-rc1-2-gbc55398 dtc: turn off dtc unit address warnings by default The newly added dtc warning to check DT unit-address without reg property and vice-versa generates lots of warnings. Turn off the check unless building with W=1 or W=2. v4.11-rc2-11-g8654cb8 dtc: update warning settings for new bus and node/property dtc gained new warnings checking PCI and simple buses, unit address formatting, and stricter node and property name checking. Disable the new dtc warnings by default as there are 1000s. As before, warnings are enabled with W=1 or W=2. The strict node and property name checks are a bit subjective, so they are only enabled for W=2. v4.16-rc3-9-g4fd98e3 scripts: turn off some new dtc warnings by default The latest dtc update adds some new noisy warnings, so turn them off by default. Disable 'avoid_unnecessary_addr_size' and 'alias_paths'. They can be re-enabled by building with 'W=1'. v4.17-rc1-27-g74656b6 kbuild: disable new dtc graph and unit-address warnings dtc gained some new warnings for OF graphs and unique unit addresses, but they are currently much too noisy. So turn off 'graph_child_address', 'graph_port', and 'unique_unit_address' warnings by default. They can be enabled by building dtbs with W=1. Build tested on imx6 and ath79 with 4.14 and 4.19. 1. https://github.com/openwrt/openwrt/pull/1694#issuecomment-450864335 Signed-off-by: Petr Štetiar <ynezz@true.cz> |

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
