On RAUC side I can't find anything so we want to tackle this task with @rgantois and @tpetazzoni.
I am not a RAUC expert so I might ask dumb questions ;)
The aim is to be able to update the firmware + bootloader alongside the update of the kernel + rootfs.
So adding a new bootchoser won't work we need to add a new core for fw update.
Would such RAUC configuration work for you?

Is there any work in progress tackling the support for PSA Firmware Update in Rauc?
If it is not the case I would like to raise the discussion about this support.
Here are the specs and the T-A documentation about PSA FWU:
https://developer.arm.com/documentation/den0118/latest/
https://trustedfirmware-a.readthedocs.io/en/latest/components/firmware-update.html
Here is some work by Sughosh Ganu from Linaro updating FWU metadata to version 2 in TF-A (merged) and U-boot (in progress):

Also work for FWU multi bank support features in Uboot:

We will also develop a tool to update fwu metadata like ubootenv tools.
If you have any pointers or ideas please go ahead to help us with the design.
