buildman: Make sure that -o is given with -w

2020-04-26T20:24:08Z

It is a bad idea to use the default output directory ('..') with -w since it does a build in that directory and writes various files these. Require that -o is given to avoid this problem. Signed-off-by: Simon Glass

buildman: Add an option to ignore migration warnings

2020-04-21T12:33:47Z

These are becoming more common now. They cause boards to show warnings which can be mistaking for compiler warnings. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Add an option to ignore device-tree warnings

2020-04-21T12:33:47Z

Unfortunately the plague of device-tree warnings has not lifted. These warnings infiltrate almost every build, adding noise and confusion. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Make -I the default

2020-04-21T12:33:47Z

At present buildman defaults to running 'mrproper' on every thread before it starts building commits for each board. This can add a delay of about 5 seconds to the start of the process, since the tools and other invariants must be rebuilt. In particular, a build without '-b', to build current source, runs much slower without -I, since any existing build is removed, thus losing the possibility of an incremental build. Partly this behaviour was to avoid strange build-system problems caused by running 'make defconfig' for one board and then one with a different architecture. But these problems were fixed quite a while ago. The -I option (which disabled mrproper) was introduced four years ago and does not seem to cause any problems with builds. So make -I the default and deprecate the option. To allow use of 'mrproper', add a new -m flag. Signed-off-by: Simon Glass

buildman: Drop the -a option

2020-04-11T01:21:06Z

There is no point in setting the ARCH environment variable since the U-Boot build system no-longer uses it. It seems safe to drop this feature since it was only recently added. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

buildman: Allow ignoring warnings in the return code

2020-04-11T01:21:06Z

Sometimes we don't want buildman to return failure if it seems warnings. Add a -W option to support this. If buildman detects warnings (and no errors) it will return an exit code of 0 (success). Note that the definition of 'warnings' includes the migration warnings produced by U-Boot, such as: ===================== WARNING ====================== This board does not use CONFIG_DM_MMC. Please update ... ==================================================== Signed-off-by: Simon Glass Reviewed-by: Tom Rini

buildman: Update help for -d

2020-04-11T01:21:06Z

This help is a bit ambiguous. It only does anything if asked to show size changes with -S. Update the help and the function comments. Signed-off-by: Simon Glass

bulidman: Add support for a simple build

2020-04-11T01:21:06Z

It is useful to run a simple build and put all the output in a single directory. Add a -w option to support this. Signed-off-by: Simon Glass

buildman: Add options to get the arch and toolchain info

2019-12-11T04:11:31Z

Sometimes it is useful for external tools to use buildman to provide the toolchain information. Add an -a option which shows the value to use for the ARCH environment variable, and -A which does the same for CROSS_COMPILE Signed-off-by: Simon Glass

buildman: Add support for building with clang

2019-01-15T00:47:13Z

Add a -O option which allows building with clang. Signed-off-by: Simon Glass
