2023-10-11doc: add documentation for gen_compile_commands.pyJoao Marcos Costa
This documentation briefly explains what is a compilation database, and how to use the script to generate one. This is not a portage, as there was no original documentation in the Linux sources. Acknowledge the documentation in the script's header and in doc/build index. Signed-off-by: Joao Marcos Costa <jmcosta944@gmail.com> Tested-by: Joao Paulo Goncalves <joao.goncalves@toradex.com>
2023-09-22Allow Python packages to be droppedSimon Glass
When building in a portage chroot, we do not have the environment needed to build pylibfdt. It is instead build as a separate package. Provide a build option to tell U-Boot to skip this part of the build. We still need it to use binman, etc. but don't need it to build its dependencies.

Mention that HTML pages are published at https://u-boot.readthedocs.io/ and that the file .readthedocs.yml controls the build process. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2023-03-08buildman: Add a flag for reproducible buildsSimon Glass
This is quite a useful thing to use when building since it avoids small size changes between commits. Add a -r flag for it. Also undefine CONFIG_LOCALVERSION_AUTO since this appends the git hash to the version string, causing every build to be slightly different. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-12-05sandbox: Rework how SDL is enabled / disabledTom Rini
Given that we can use Kconfig logic directly to see if we have a program available on the host or not, change from passing NO_SDL to instead controlling CONFIG_SANDBOX_SDL in Kconfig directly. Introduce CONFIG_HOST_HAS_SDL as the way to test for sdl2-config and default CONFIG_SANDBOX_SDL on if we have that, or not.

2022-09-02Makefile: Allow LTO to be disabled for a buildSimon Glass
LTO (Link-Time Optimisation) is an very useful feature which can significantly reduce the size of U-Boot binaries. So far it has been made available for selected ARM boards and sandbox. However, incremental builds are much slower when LTO is used. For example, an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7 seconds with LTO enabled. Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be disabled during development if needed, for faster builds. Add some documentation about LTO while we are here.

2021-10-19Makefile: Only build dtc if neededSimon Glass
At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined, even when DTC is provided. The built dtc is not actually used, so this is a waste of time. Update the Makefile logic to build dtc only if one is not provided to the build with the DTC variable. Add documentation to explain this. This saves about 3.5 seconds of elapsed time on a clean build of sandbox_spl for me. Signed-off-by: Simon Glass <sjg@chromium.org>
