buildman: allow more incremental building

2016-05-17T15:54:43Z

One use-case for buildman is to continually run it interactively after each small step in a large refactoring operation. This gives more immediate feedback than making a number of commits and then going back and testing them. For this to work well, buildman needs to be extremely fast. At present, a couple issues prevent it being as fast as it could be: 1) Each time buildman runs "make %_defconfig", it runs "make mrproper" first. This throws away all previous build results, requiring a from-scratch build. Optionally avoiding this would speed up the build, at the cost of potentially causing or missing some build issues. 2) A build tree is created per thread rather than per board. When a thread switches between building different boards, this often causes many files to be rebuilt due to changing config options. Using a separate build tree for each board would avoid this. This does put more strain on the system's disk cache, but it is worth it on my system at least. This commit adds two command-line options to implement the changes described above; -I ("--incremental") turns of "make mrproper" and -P ("--per-board-out-dir") creats a build directory per board rather than per thread. Tested: ./tools/buildman/buildman.py tegra ./tools/buildman/buildman.py -I -P tegra ./tools/buildman/buildman.py -b tegra_dev tegra ./tools/buildman/buildman.py -b tegra_dev -I -P tegra ... each once after deleting the buildman result/work directory, and once "incrementally" after a previous identical invocation.

buildman: Clarify the use of -V

2016-03-18T03:27:39Z

This option outputs to the log file, not to the terminal. Clarify that in the help, and add a mention of it in the README. Signed-off-by: Simon Glass Reported-by: Stephen Warren Reviewed-by: Stephen Warren

buildman: Add a way to specific a full toolchain prefix

2016-03-18T03:27:39Z

At present buildman allows you to specify the directory containing the toolchain, but not the actual toolchain prefix. If there are multiple toolchains in a single directory, this can be inconvenient. Add a new 'toolchain-prefix' setting to the settings file, which allows the full prefix (or path to the C compiler) to be specified. Update the documentation to match.

tools: Update openrisc toolchain information

2016-02-24T23:44:11Z

Since commit 87da2690ab81b5f29f83dc85c55f933e6ef414bc "openrisc: updating build tools naming convention", openrisc kernel.org toolchain is out of date and cannot build U-Boot. Update buildman and moveconfig tools to refer to the new one. Signed-off-by: Bin Meng

buildman: README: add links for toolchains not available on kernel.org

buildman: Add the option to download toolchains from kernel.org

2015-01-15T05:16:54Z

The site at https://www.kernel.org/pub/tools/crosstool/ is a convenient repository of toolchains which can be used for U-Boot. Add a feature to download and install a toolchain for a selected architecture automatically. It isn't clear how long this site will stay in the current place and format, but we should be able to rely on bug reports if it changes.
