TF-M includes platform/ext/cmsis, which is CMSIS v5.9.0 with some TF-M-specific changes. Looking at the history for that directory, it seems that we periodically update it and have to re-apply the TF-M-specific changes (which looks to be the naming of the stack and the copy table size).
I'm wondering whether there's a plan to either push the TF-M changes into upstream CMSIS or to change TF-M so that they're not needed? It would be nice to just pull CMSIS from upstream like we do with other external libraries...

Hi Chris,
We are currently working on this; you can expect a patch soon to use vanilla CMSIS headers. As it is affecting all the platforms minimally, review is going to be requested through the mailing list as usual.
Best regards,
