I have been tasked with making the twincpu feature work with the IAR toolchain, and I started out trying to build it with clang and gcc but it seems there's some issues with it.

I tried using the psoc6 target, but it appears that none of the v6/v7 targets are supported in configs/ConfigDefault.cmake. If I add that the build then fails with a complaint about "Armv6-M/Armv7-M can only support multi-core TF-M now." from tfm_arch_v6m_v7m.h, due to TFM_MULTI_CORE_TOPOLOGY not being set, but that appears to be set in one of the cmake files so I guess something is currently broken.

Is this a known issue and is there are known fix?
