Add support for specifying the parameters needed for capsule generation through a config file, instead of passing them through command-line. Parameters for more than a single capsule file can be specified, resulting in generation of multiple capsules through a single invocation of the command.
The config file can then be passed to the mkeficapsule tool in such manner
$ ./tools/mkeficapsule -f <path/to/the/config/file>

This patch keeps coming back :-)
Can we not add multiple capsules in the binman description? Why do we need a new file format? How can binman decode images produced in this way?
So as Tom mentions, this brings parity with respect to the other capsule generation tool in EDKII that generates capsules. IIRC, this is something which even Xilix was interested in, and Michal had kind of gone through these patches earlier. Lastly, it would be good to have support in U-Boot's mkeficapsule tool for generating a single capsule file with multiple payloads, and having support for this functionality helps in that goal.
Also, you might have noticed that, since your objection to the last series, I have removed putting this in binman. So now, this aspect of the capsule generation would only be supported through the command-line invocation of the tool.
I think that overall the approach is sane. mkeficapsule is currently supported and compiled for distros, so the multiple payload support is useful. If we want to add support to binman, instead of rewriting this in python, we could just call that tool for parsing and creating capsules
Thanks /Ilias
Also, could we get sandbox to produce one EFI capsule as part of the normal build? I think that discussion trailed off.
Yes, apologies for missing out on this. Slipped my mind. Would you want, say, all the non-signed capsules to be generated as part of the sandbox build?
