+Subject: build: Fix GRUB i386-pc build with Ubuntu gcc
+
+With recent versions of gcc on Ubuntu a very large lzma_decompress.img file is
+output. (e.g. 134479600 bytes instead of 2864.) This causes grub-mkimage to
+fail with: "error: Decompressor is too big."
+
+This seems to be caused by a section .note.gnu.property that is placed at an
+offset such that objcopy needs to pad the img file with zeros.
+
+This issue is present on:
+Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0
+Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008
+
+This issue is not present on:
+Ubuntu 19.10 with gcc (Ubuntu 7.5.0-3ubuntu1~19.10) 7.5.0
+RHEL 8.0 with gcc 8.3.1 20190507 (Red Hat 8.3.1-4)
+
+The issue can be fixed by removing the section using objcopy as shown in
+this patch.

-x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
-32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
-R_X86_64_PC32.

+Newer glibc versions does not include sys/sysmacros.h from sys/types.h
+anymore.  Including it unconditionally should be safe.
+
+See https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html for why

+This is due to gnu-efi commit 486ba3c3bdd147b7d98159b9e650be60bce0f027
+("Do not include efisetjmp.h on efi.h"), in which they state:
+
+    Do not include efisetjmp.h on efi.h
+
+    People than really want to use efisetjmp implementation can include
+    the header on their own.
+
+    Signed-off-by: leo <leo.sartre@geebol.fr>
+
+So we act as specified, and include <efisetjmp.h> from efi/main.c.

+=== Top-level parallel build
+
+.Note
+This section deals with a very experimental feature, which is known to
+break even in some non-unusual situations. Use at your own risk.
+
+Buildroot has always been capable of using parallel build on a per
+package basis: each package is built by Buildroot using +make -jN+ (or
+the equivalent invocation for non-make-based build systems). The level
+of parallelism is by default number of CPUs + 1, but it can be
+adjusted using the +BR2_JLEVEL+ configuration option.
+
+Until 2020.02, Buildroot was however building packages in a serial
+fashion: each package was built one after the other, without
+parallelization of the build between packages. As of 2020.02,
+Buildroot has experimental support for *top-level parallel build*,
+which allows some signicant build time savings by building packages
+that have no dependency relationship in parallel. This feature is
+however marked as experimental and is known not to work in some cases.
+
+In order to use top-level parallel build, one must:
+
+. Enable the option +BR2_PER_PACKAGE_DIRECTORIES+ in the Buildroot
+configuration
+
+. Use +make -jN+ when starting the Buildroot build
+
+Internally, the +BR2_PER_PACKAGE_DIRECTORIES+ will enable a mechanism
+called *per-package directories*, which will have the following
+effects:
+
+* Instead of a global _target_ directory and a global _host_ directory
+  common to all packages, per-package _target_ and _host_ directories
+  will be used, in +$(O)/per-package/<pkg>/target/+ and
+  +$(O)/per-package/<pkg>/host/+ respectively. Those folders will be
+  populated from the corresponding folders of the package dependencies
+  at the beginning of +<pkg>+ build. The compiler and all other tools
+  will therefore only be able to see and access files installed by
+  dependencies explicitly listed by +<pkg>+.
+
+* At the end of the build, the global _target_ and _host_ directories
+  will be populated, located in +$(O)/target+ and +$(O)/host+
+  respectively. This means that during the build, those folders will
+  be empty and it's only at the very end of the build that they will
+  be populated.

+==== Build an external toolchain with Buildroot
+
+The Buildroot internal toolchain option can be used to create an
+external toolchain. Here are a series of steps to build an internal
+toolchain and package it up for reuse by Buildroot itself (or other
+projects).
+
+Create a new Buildroot configuration, with the following details:
+
+* Select the appropriate *Target options* for your target CPU
+  architecture
+
+* In the *Toolchain* menu, keep the default of *Buildroot toolchain*
+  for *Toolchain type*, and configure your toolchain as desired
+
+* In the *System configuration* menu, select *None* as the *Init
+  system* and *none* as */bin/sh*
+
+* In the *Target packages* menu, disable *BusyBox*
+
+* In the *Filesystem images* menu, disable *tar the root filesystem*
+
+Then, we can trigger the build, and also ask Buildroot to generate a
+SDK. This will conveniently generate for us a tarball which contains
+our toolchain:
+
+-----
+make sdk
+-----
+
+This produces the SDK tarball in +$(O)/images+, with a name similar to
++arm-buildroot-linux-uclibcgnueabi_sdk-buildroot.tar.gz+. Save this
+tarball, as it is now the toolchain that you can re-use as an external
+toolchain in other Buildroot projects.
+
+In those other Buildroot projects, in the *Toolchain* menu:
+
+* Set *Toolchain type* to *External toolchain*
+
+* Set *Toolchain* to *Custom toolchain*
+
+* Set *Toolchain origin* to *Toolchain to be downloaded and installed*
+
+* Set *Toolchain URL* to +file:///path/to/your/sdk/tarball.tar.gz+

+=== Using the run-tests framework
+
+Buildroot includes a run-time testing framework called run-tests built
+upon Python scripting and QEMU runtime execution. There are two types of
+test cases within the framework, one for build time tests and another for
+run-time tests that have a QEMU dependency. The goals of the framework are
+the following:
+
+* build a well defined configuration
+* optionally, verify some properties of the build output
+* if it is a run-time test:
+** boot it under QEMU
+** run some test condition to verify that a given feature is working
+
+The run-tests tool has a series of options documented in the tool's help '-h'
+description. Some common options include setting the download folder, the
+output folder, keeping build output, and for multiple test cases, you can set
+the JLEVEL for each.
+
+Here is an example walk through of running a test case.
+
+* For a first step, let us see what all the test case options are. The test
+cases can be listed by executing +support/testing/run-tests -l+. These tests
+can all be run individually during test development from the console. Both
+one at a time and selectively as a group of a subset of tests.

+---------------------
+
+Those runtime tests are regularly executed by Buildroot Gitlab CI
+infrastructure, see .gitlab.yml and https://gitlab.com/buildroot.org/buildroot/-/jobs.
+
+==== Creating a test case
+
+The best way to get familiar with how to create a test case is to look at a
+few of the basic file system +support/testing/tests/fs/+ and init
++support/testing/tests/init/+ test scripts. Those tests give good examples
+of a basic build and build with run type of tests. There are other more
+advanced cases that use things like nested +br2-external+ folders to provide
+skeletons and additional packages.
+
+The test cases by default use a br-arm-full-* uClibc-ng toolchain and the
+prebuild kernel for a armv5/7 cpu. It is recommended to use the default
+defconfig test configuration except when Glibc/musl or a newer kernel are
+necessary. By using the default it saves build time and the test would
+automatically inherit a kernel/std library upgrade when the default is
+updated.
+
+The basic test case definition involves
+
+* Creation of a new test file
+* Defining a unique test class
+* Determining if the default defconfig plus test options can be used
+* Implementing a +def test_run(self):+ function to optionally startup the
+emulator and provide test case conditions.
+
+Beyond creating the test script, there are a couple of additional steps that
+should be taken once you have your initial test case script. The first is
+to add yourself to the +DEVELOPERS+ file to be the maintainer of that test
+case. The second is to update the Gitlab CI yml by executing
++make .gitlab-ci.yml+.
+
+==== Debugging a test case
+
+Within the Buildroot repository, the testing framework is organized at the
+top level in +support/testing/+ by folders of +conf+, +infra+ and +tests+.
+All the test cases live under the +test+ folder and are organized in various
+folders representing the catagory of test.
+
+Lets walk through an example.
+
+* Using the Busybox Init system test case with a read/write rootfs
++tests.init.test_busybox.TestInitSystemBusyboxRw+
+* A minimal set of command line arguments when debugging a test case would
+include '-d' which points to your dl folder, '-o' to an output folder, and
+'-k' to keep any output on both pass/fail. With those options, the test will
+retain logging and build artifacts providing status of the build and
+execution of the test case.
+
+---------------------
+$ support/testing/run-tests -d dl -o output_folder -k tests.init.test_busybox.TestInitSystemBusyboxRw
+15:03:26 TestInitSystemBusyboxRw                  Starting
+15:03:28 TestInitSystemBusyboxRw                  Building
+15:08:18 TestInitSystemBusyboxRw                  Building done
+15:08:27 TestInitSystemBusyboxRw                  Cleaning up
+.
+Ran 1 test in 301.140s
+
+OK
+---------------------
+
+* For the case of a successful build, the +output_folder+ would contain a
+<test name> folder with the Buildroot build, build log and run-time log. If
+the build failed, the console output would show the stage at which it failed
+(setup / build / run). Depending on the failure stage, the build/run logs
+and/or Buildroot build artifacts can be inspected and instrumented. If the
+QEMU instance needs to be launched for additional testing, the first few
+lines of the run-time log capture it and it would allow some incremental
+testing without re-running +support/testing/run-tests+.
+
+* You can also make modifications to the current sources inside the
++output_folder+ (e.g. for debug purposes) and rerun the standard
+Buildroot make targets (in order to regenerate the complete image with
+the new modifications) and then rerun the test. Modifying the sources
+directly can speed up debugging compared to adding patch files, wiping the
+output directoy, and starting the test again.
+
+---------------------
+$ ls output_folder/
+TestInitSystemBusyboxRw/
+TestInitSystemBusyboxRw-build.log
+TestInitSystemBusyboxRw-run.log
+---------------------
+
+* The source file used to implement this example test is found under
++support/testing/tests/init/test_busybox.py+. This file outlines the
+minimal defconfig that creates the build, QEMU configuration to launch
+the built images and the test case assertions.
+
+To test an existing or new test case within Gitlab CI, there is a method of
+invoking a specific test by creating a Buildroot fork in Gitlab under your
+account. This can be handy when adding/changing a run-time test or fixing a
+bug on a use case tested by a run-time test case.
+
+
+In the examples below, the <name> component of the branch name is a unique
+string you choose to identify this specific job being created.
+
+* to trigger all run-test test case jobs:
+
+---------------------
+ $ git push gitlab HEAD:<name>-runtime-tests
+---------------------
+
+* to trigger one test case job, a specific branch naming string is used that
+includes the full test case name.
+
+---------------------
+ $ git push gitlab HEAD:<name>-<test case name>
