Just to clarify: are you using "bloblist" as a general term for the concept
of a simple linked list of tagged data blobs, or to refer specifically to
the U-Boot implementation with that name? The existing TF-A implementation
(bl_aux_params) is basically identical in concept to the U-Boot bloblist,
but not binary compatible. Are we talking about just keeping that, or
throwing it away in order to reimplement the exact structure U-Boot is
using? (I would prefer to keep the bl_aux_params as they are to avoid
disrupting existing uses, of course. Making backwards-incompatible changes
to an interface that passes across multiple repos and firmware components
is always a big pain.)
