@Patater could you please detail what testing has been done on this prior to the PR landing ? Or do we expect our nightly testing to be sufficient?

We've used TF-M 1.0 to generate mcuboot.bin and used that with this PR to run the Mbed OS + TF-M regression tests successfully (https://github.com/ARMmbed/mbed-os-tf-m-regression-tests/). Further work would be needed to update mcuboot in Mbed OS in a follow-up PR if we want to use the new mcuboot.

This will be automatically tested when CI tests mbed-os-example-psa with the ARM_MUSCA_B1 target as requested in examples.json.
