Now that the Arm-M4 CPU has been added to QEMU we can add the Netduino
Plus 2 machine. This is very similar to the STM32F205 and Netduino 2 SoC
and machine.

v6:
 - Remove machine specific reset code
 - Rebase on master
v5:
 - Fix checkpatch failures
 - Add mising includes
v4:
 - Rebase on master
v3:
 - Remove custom reset handler
 - Add init-entry and init-sp properties
 - Rebase on master (including Kconfig changes)
v2:
 - Reorder patchset
 - Return the kernel entry point instead of using a pointer
 - Address Peter's comments

Alistair Francis (4):
  hw/misc: Add the STM32F4xx Sysconfig device
  hw/misc: Add the STM32F4xx EXTI device
  hw/arm: Add the STM32F4xx SoC
  hw/arm: Add the Netduino Plus 2

I'm not sure this is correct, don't you need to set the bit in the 
exti_pr register regardless it is masked? Else in masked polling mode 
the guest will never see IRQ delivered.

So I'd drop this if statement, ...

... do not pulse here, ...

... do not pulse here, ...

> +    }

... and here pulse if not masked:

        if (!((1 << irq) & s->exti_imr)) {
            /* Interrupt is masked */
            return;
        }
        qemu_irq_pulse(s->irq[irq]);

(Or invert the if condition).

Something odd has happened here -- your patch 1/4 already
had a stanza:

+config NETDUINOPLUS2
+    bool
+    select STM32F405_SOC

so either that should be in this patch or this fragment here
should just be deleted.

Assuming you sort that out,
