Omnibus series of ARM-related patches (noticed during the
"split accel" PoC work).

- Usual prototypes cleanups
- Check TCG for EL2/EL3 features (and not !KVM or !HVF)
- Improve HVF debugging
- Correct HVF 'dtb_compatible' value for Linux
- Fix HVF GTimer frequency (My M1 hardware has 24 MHz)
  (this implies accel/ rework w.r.t. QDev vCPU REALIZE)

Regards,

Phil.

Philippe Mathieu-Daudé (20):
  target/arm: Remove arm_handle_psci_call() stub
  target/arm: Reduce arm_cpu_post_init() declaration scope
  target/arm: Unify gen_exception_internal()
  target/arm/hvf: Simplify GIC hvf_arch_init_vcpu()
  target/arm/hvf: Directly re-lock BQL after hv_vcpu_run()
  target/arm/hvf: Trace hv_vcpu_run() failures
  accel/hvf: Trace VM memory mapping
  target/arm/hvf: Log $pc in hvf_unknown_hvc() trace event
  target/arm/hvf: Correct dtb_compatible value
  target/arm: Restrict system register properties to system binary
  target/arm: Create GTimers *after* features finalized / accel realized
  accel: Keep reference to AccelOpsClass in AccelClass
  accel: Introduce AccelOpsClass::cpu_target_realize() hook
  accel/hvf: Add hvf_arch_cpu_realize() stubs
  target/arm/hvf: Really set Generic Timer counter frequency
  hw/arm/virt: Only require TCG || QTest to use TrustZone
  hw/arm/virt: Only require TCG || QTest to use virtualization extension
  hw/arm/virt: Rename cpu_post_init() -> post_cpus_gic_realized()
  hw/arm/sbsa-ref: Tidy up use of RAMLIMIT_GB definition
  tests/functional/sbsa-ref: Move where machine type is set
