Re: [PATCH v3 9/9] buildman: Add --allow-missing flag to allow missing blobs

On 11/6/22 00:04, Simon Glass wrote:

From: Tom Rini trini@konsulko.com

Add a new flag to buildman so that we will in turn pass BINMAN_ALLOW_MISSING=1 to 'make'. Make use of this flag in CI.

Please, document all arguments of binman in doc/develop/package/binman.rst.

Best regards

Heinrich

Allow the settings file to control this.

+Support for binary blobs +------------------------

+U-Boot is moving to using Binman (see :doc:`../develop/package/binman`) for +dealing with the complexities of packaging U-Boot along with binary files from +other projects. These are called 'external blobs' by Binman.

+Typically a missing external blob causes a build failure. For build testing of +a lot of boards, or boards for which you do not have the blobs, you can use the +-M flag to allow missing blobs. This marks the build as if it succeeded, +although with warnings shown, including 'Some images are invalid'. If any boards +fail in this way, buildman exits with status 101.

+To convert warnings to errors, use -E. To make buildman return success with +these warnings, use -W.

+It is generally safe to default to enabling -M for all runs of buildman, so long +as you check the exit code. To do this, add::

• allow-missing = "always"

+to the top of the buildman_settings_ file.
