[ACTIVITY] report week ending 5 Feb

Progress: * UM-2 [QEMU upstream maintainership] + lots of code review this week, including another round of rth's MTE user-mode patchset

* QEMU-364 [QEMU support for ARMv8.1-M extensions] + Sent out an RFC proposing some more Clock API changes (since it'll be a while before I'm ready to post the series with the new timer device that requires them) + The SSE-200 Cortex-M33-based MPS3 AN524 FPGA image is a useful target to model: the Zephyr folks would like it, and it is a good stepping stone to an MPS3 FPGA image with a Cortex-M55/SSE-300 in it. Wrote a patchset for an mps3-an524 board model, and sent it out for review.
