My impression is that the newly added phones are still fairly rudimentary,
but some others that were added in the past releases have gotten
further. I don't know any details, but I've added Konrad to Cc, he can
comment on his work.

One of the missing pieces with the OMAP based phones has always
been the GPU, and on that front I think by now almost every other GPU
is ahead.

PostmarketOS is probably the right place to look for this.
