Progress: * VIRT-65 [QEMU upstream maintainership] + tracked down and sent fix for bug in MPU handling of exception frame unstacking that broke a Zephyr test case + sent some patches for minor GICv2 bugs + code review: - large series adding virtualization support to GICv2 * VIRT-164 [improve Cortex-M emulation] + completed patchset that implements execution from small MPU regions and MMIO regions, and sent it out for review + found and fixed a few bugs in the code I was modifying in the process
