2025-05-09Dockerfile: use lz4 instead of lz4-toolsHeinrich Schuchardt
Since Ubuntu Jammy lz4-tools is only a virtual package which pulls in lz4 as dependency. Update documentation too. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2025-04-24python: Use and refer to the venv module rather than virtualenvTom Rini
Using some form of sandbox with Python modules is a long standing best practice with the language. There are a number of ways to have a Python sandbox be created. At this point in time, it seems the Python community is moving towards using the "venv" module provided with Python rather than a separate tool. To match that we make the following changes: - Refer to a "Python sandbox" rather than virtualenv in comments, etc. - Install the python3-venv module in our container and not virtualenv. - In our CI files, invoke "python -m venv" rather than "virtualenv". - In documentation, tell users to install python3-venv and not virtualenv.

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>
