It looks like legacy branch has been cleaned from upstream, only master remains

https://github.com/zephyrproject-rtos/trusted-firmware-m/branches

I used the revision on earlier version assuming it's closer to what we used before.

Also for the record USB console is working as documented at:

https://docs.oniroproject.org/projects/blueprints/en/latest/transparent-gateway.html

which is not the case in kirkstone branch
I'll diff to narrow the problem.
