I've posted a design document for bootloader changes to support twin cpu at https://developer.trustedfirmware.org/w/tf_m/design/twin-cpu/bootloader/
There are efforts underway to get the TF-M changes to the bootloader contributed back to the upstream MCUboot project.
We should be trying to make sure that we continue this effort, as well as to make sure that any efforts to extend the bootloader are done upstream, and not in the TF-M-specific branch.
Are you expecting to be running the non-secure CPU before the secure CPU has finished verifying the images?
