dtoc: Convert to use ArgumentParser

2021-07-21T16:27:33+00:00

Use this parser instead of OptionParser, which is deprecated. Signed-off-by: Simon Glass Reviewed-by: Walter Lozano

dtoc: Add an option for device instantiation

2021-03-22T06:23:27+00:00

Add an option to instantiate devices at build time. For now this just parses the option and sets up a few parameters. Signed-off-by: Simon Glass

dtoc: Support tracking the phase of U-Boot

2021-03-22T06:23:27+00:00

U-Boot operates in several phases, typically TPL, SPL and U-Boot proper. The latter does not use dtoc. In some rare cases different drivers are used for two phases. For example, in TPL it may not be necessary to use the full PCI subsystem, so a simple driver can be used instead. This works in the build system simply by compiling in one driver or the other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has no way of knowing which code is compiled in for which phase, since it does not inspect Makefiles or dependency graphs. So to make this work for dtoc, we need to be able to explicitly mark drivers with their phase. This is done by adding an empty macro to the driver. Add support for this in dtoc.

dtoc: Save scan information across test runs

2021-03-22T06:23:27+00:00

At present most of the tests scan the U-Boot source tree as part of their run. This information does not change across tests, so we can save time by remembering it. Add a way to set up this information and use it for each test, taking a copy first, so as not to mess up the original. This reduces the run time from about 1.6 seconds to 1.5 seconds on my machine. For code coverage (which cannot run in parallel), it reduces from 33 seconds to 5. Signed-off-by: Simon Glass

dtoc: Move src_scan tests to a separate file

2021-01-05T19:26:35+00:00

Move the tests related to scanning into their own class, updating them to avoid using dtb_platdata as a pass-through. Signed-off-by: Simon Glass

dtoc: Run tests using test_util

2021-01-05T19:26:35+00:00

Use the standard function for running tests and reported results. This allows the tests to run in parallel, which is a significant speed-up on most machines (e.g. 4.5 seconds -> 1.5s on mine). Signed-off-by: Simon Glass

dtoc: Add an 'all' command

2021-01-05T19:26:35+00:00

With upcoming changes, dtoc will output several files for different of-platdata components. Add a way to output all ava!ilable files at once ('all'), to the appropriate directories, without needing to specify each one invidually. This puts the commands in alphabetical order, so update the tests accordingly. Signed-off-by: Simon Glass

dtoc: Allow providing a directory to write files to

2021-01-05T19:26:35+00:00

At present dtoc writes only a single file on each invocation. U-Boot writes the two files it needs by separate invocations of dtoc. Since dtoc now scans all U-Boot driver source, this is fairly slow (about 1 second per file). It would be better if dtoc could write all the files at once. In preparation for this, add a way to specify an output directory for the files. Signed-off-by: Simon Glass

dtoc: Use None to mean stdout

2021-01-05T19:26:35+00:00

At present dtoc uses '-' internally to mean that output should go to stdout. This is not necessary and None is more convenient. Update it. Signed-off-by: Simon Glass

patman: Tidy up sys.path changes

2020-04-26T20:25:21+00:00

Now that we are using absolute paths we can remove some of the sys.path mangling that appears in the tools. We only need to add the path to 'tools/' so that everything can find modules relative to that directory. The special paths for finding pylibfdt remain. Signed-off-by: Simon Glass
