Sorry Thomas - Someday I'll get that IAR license working and stop breaking support every 5 seconds. Thanks for all the hard work and fixes.
Patches look good, have reviewed.

Just when you think you have nailed everfything down, you decide to start with a fresh clone and stuff don't build anymore ;)
See: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6766
I have now gone over and tried building everything that has IAR support and here are my findings.
I have used the following patches: https://review.trustedfirmware.org/c/TF-M/tf-m-tests/+/5978 https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6766
I have built for the following targets: musca_a mps2/an519 mps2/an521 mps2/an539 mps2/sse-200_aws mps3/an524 cypress/psoc64 nxp/lpcxpresso55s69 (-DBL2=False as bl2 support appears to have been added recently to this target) stm/nucleo_l552ze_q stm/stm32l562e_dk
The mps2/fvp_sse300 requires a compiler with support for the M55, and the IAR compiler with support for this is not yet released.
I have run tests on the following targets: musca_a mps2/an519 mps2/an521 mps2/an539
The cypress/psoc64 board I have appears to be obsolete now and I could not flash the secure image to it.
The nuvoton/m2351 appears to have IAR support, but it appears untested as it gives linking errors for the bl2 and NS startup files.
There are some old and new warnings for type issues and some other minor things.
The QCBOR NaN tests are still failing, see: https://developer.trustedfirmware.org/T700
This really is an issue where the ARM ABI and IEEE 754 are incompatible and we are following the ARM ABI. In reality neither ARMCLANG nor GNUARM are fully ARM ABI compliant as they are not ignoring the relevant bits.
