[ACTIVITY] report week ending 16 Mar

[Peter Maydell]

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ raspi3 board: tested with a Debian kernel, and fixed and sent
patches for various issues that were causing it to panic.
Unfortunately there's a more tricky issue with the sd controller
still that means it doesn't boot yet...
+ bug investigation week:
- LP:1748434: wrong logic for ICC_PMR and ICC_RPR accesses by NS code
when the GICv3 emulation has security extensions enabled. Sent patch.
- LP:1751674: segfault doing a VM memory dump on vexpress-a9. This is
a combination of user error and a longstanding bug where the GICv2
crashes if you try to read its banked-per-CPU registers from a context
that isn't a guest CPU (like the monitor or the gdbstub)
- LP:1755479: confirmed that crash when using -icount is one that has
been fixed by a patch from Pavel that was lurking in a record/replay series
+ handling all the merge requests for softfreeze
* VIRT-164 [improve Cortex-M emulation]
+ started to look at implementing the stack-limit checking feature
