[ACTIVITY] report week ending 25 May

Progress: * VIRT-65 [QEMU upstream maintainership] + sent patch for minor bug where FRECPX was not honouring FPCR.FZ + looking at migration failure for TCG VMs using Secure mode. I know what the bug is, but need to figure out how to fix it without breaking migration compatibility for TCG VMs which don't use Secure mode... + various miscellaneous minor bug fixing and code review * VIRT-164 [improve Cortex-M emulation] + MPC emulation: - sent out first version of patchset that implements the required IOMMU core code features and the MPC device that uses them; fielded various code review discussions on it

thanks -- PMM
