Can you explain a bit more the pain points you are seeing in u-boot with
submodules?  EDK2 does submodules for openSSL and it's quite convenient,
since you dont have to maintain any code, do backports etc.  Instead we can
just use upstream projects as-is.
IMHO we should work on having it as an experimental feature in parallel
with the current TCP efforts for a while and have a Kconfig switch.  If we
are happy in the long run and the code increase isn't prohibitive, we can
consider switching permanently
