Note that if you just do a build-all you're going to see a code size, for Arm,
of maybe 700K or so (because you're getting support for PGP, SSH, TLS, S/MIME,
X.509, OCSP, CMP, TSP, and who knows what else).  You can cut it down to much
less depending on what you disable (for example about 260K for a TLS server
using Thumb instructions), but it depends on what functionality you need.
This is why we need a list of goals, what functionality is needed, how much
flash/RAM do we have, and so on.

Peter.
