Regarding capsule update,

As some of you may know, I'm going to submit a RFC patch series for UEFI capsule support on U-Boot in a week or so (maybe). With this patch, we will support "Capsule-on-Disk" only (but without authentication implemented).
One of my concerns here is about "variable update via a capsule" as an alternative of "SetVariable at runtime," where values to be set for variables will be exported as a capsule file and all the updates will take place after rebooting. This is very useful on systems where SetVariable is not available at runtime for some reasons.
Sure that's really useful and that's the direction we decided to follow.
Some idea has been proposed by Peter[1], but the discussion has been stalled for a long time.

We hope to allocate some resources and work on it in the following months, so we'll revive this thread once we do. Thanks for the pointers.
