Hi Simon

I haven't read this patch in detail, but I have a general request
regarding changes to the bloblist layout: Backwards compatibility - in
the sense that, if the bloblist is generated by SPL from 2020.04, that
should also be usable from a U-Boot proper as of 2021.01 etc.

While I/we don't actually use bloblist currently, we have some ideas for
what we might use it for on various boards. But, on at least one board,
our SPL is stored in read-only storage after production, while we have
redundant (and updatable) copies of U-Boot proper - so it's important
that a future U-Boot can also grok a bloblist generated by earlier code.

Is that guaranteed?

Thanks,
Rasmus
