I think its a good idea, but Ross's point is good too. If optee is forked
for every architecture that can not be a good thing. However, if we can get
qemuarm64 and qemuriscv64 based machines use an upstream version reliably,
we might be able to even help upstream to keep things sane
atleast for emulated machine architecture, similar to u-boot.
