[ACTIVITY] report week ending 3 Aug

[Peter Maydell]

Progres:s
* VIRT-65 [QEMU upstream maintainership]
+ some time spent getting testing on BSD VMs working again (the box I
use for this was replaced with new hardware, which seemed like a good
time to shift to the support for this we have in upstream QEMU)
+ pre-Connect scrub of Linaro JIRA tasks to check they're up to date
+ sent some more "convert devices away from old_mmio API" patches
+ usual release work
* VIRT-164 [improve Cortex-M emulation]
+ finished, tested and sent patchset implementing MPS2 FPGAIO counters
and the CMSDK dual-timer device
+ implemented model of CMSDK watchdog timer
+ implemented minimal version of IoTKit system control element registers
+ started on modelling the Master Security Controller (which gates
transactions from bus master peripherals like DMA controllers)

thanks

[TCWG-1450] Support for Tag_ABI_VFP_args in LLD
Needed by FreeBSD in order to switch to LLD for Arm.

[TCWG-1451] Support for v5 and v6 Arm in LLD
Tidied up and submitted patches for v5/v6 (branch encoding and
compatible thunks), in upstream review.

[TCWG]
- Started doing some Jira gardening in preparation for status report
- Went back to libfuzzer hang on AArch64 buildbot. Looks like failure
to converge on -O2 and above, from the logs and code-generation I
suspect that it isn't handling the CINC instruction well (not
increasing coverage when the condition passes).
