[PATCH v3 0/6] Fix handling of optional blobs in binman

[Bryan Brattlof]

On June 13, 2025 thus sayeth Yannic Moog:
> This series solves a contradiction regarding ext blobs packaged in
> binman. When they are marked as optional, by default they are faked, two
> messages are emitted. One says the image is not functional the other
> says the image is still functional. Both concern the same binman
> entry/blob.
> 
> Binman is set up to have fake external blobs in case they are missing.
> This is regardless on whether they are optional or not.
> The implementation does not allow different types of entries to override
> the faking decision; at least there wouldn't be much sense in doing so.
> 
> Here is an example build output of a phycore-imx8mp:
> 
>   BINMAN  .binman_stamp
> Image 'image' is missing optional external blobs but is still functional: tee-os
> 
> /binman/section/fit/images/tee/tee-os (tee.bin):
>    See the documentation for your board. You may need to build Open Portable
>    Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin
> 
> Image 'image' has faked optional external blobs and is still functional: tee.bin
> 
>   OFCHK   .config
> 
> The output stays to inform/warn the user, but in this case the tee-os
> entry will not be present in the final image.
> 
> ---
> Changes in v3:
> - Fix all failing tests
>   - add commit that reworks bin.elf test
>   - add section data to failing tests. E.g. tee-os contains missing
>     tee.bin, but is still included in the image.
> - remove _entries -> GetEntries() refactor patch
> - reorder commits -> smaller fixes before refactor EDITME: use bulletpoints and terse descriptions.
> - squash commits so that for each commits all binman tests should pass now
> - rebase on next
> - Link to v2: https://lore.kernel.org/r/20250527-binman_faked_optional-v2-0-3362ab897581@phytec.de

Thanks for fixing this. That error message has been on my todo list for 
a while as well :)
