Re: Cortex-M33 and Arm TrustZone ?
I have definite plans for this, just waiting for the L5 to become available.
The general idea is to make a port to run RT/NIL in TZ as trusted OS on top of another OS running in non trusted mode (another RT/NIL or something else entirely).

Yes, the trusted OS would expose "services" to the non-trusted code.
The API will be very simple, just communication, each service would define its own API. Look at services as threads in TZ exposing something like a mailbox.

It is pretty high priority, I will order the board ASAP. First we will have the normal RT/NIL/HAL support, TZ support will follow.
We also need OpenOCD support, I hope it will be available soon.
