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.
Allow the settings file to control this.

Changes in v5: - Split out config_fname change into a separate patch - Rename GetGlobalValue to GetGlobalItemValue - Fix 'items' typo - Simplify implementation of GetGlobalItemValue() - Use '[global]' for the doc heading - Use double tick for arguments - Drop redundant allow_missing code - Split out the tests more
Changes in v4: - Various changes that were unfortunately not recorded
Changes in v3: - Add tests docs and a settings-file option

+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. + + Changing the configuration --------------------------
