[Qemu-devel] [PATCH 0/9] disentangle NVIC from ARM GIC

[Peter Maydell <peter.maydell@linaro.org>]

This patch series refactors the ARMv7M NVIC so it no longer
textually includes arm_gic.c Instead we have a single common
base class which has the state struct, and a subclass for
the GIC and another for the NVIC.

As well as being generally rather nicer, this lays the
groundwork for supporting a KVM in-kernel irqchip by
getting the NVIC out of our hair. (My current KVM support
code is another couple of patches on top of this which add
a third subclass of ARMGICCommon which is the KVM model.)

(Not intended for 1.1, but I expect I'll put it into my
arm-devs.next tree to go a pullreq after master reopens
for 1.2.)

Peter Maydell (9):
  hw/arm_gic: Remove NVIC ifdefs from gic_state struct
  hw/arm_gic: Remove the special casing of NCPU for the NVIC
  hw/arm_gic: Move NVIC specific reset to armv7m_nvic_reset
  hw/armv7m_nvic: Use MemoryRegions for NVIC specific registers
  hw/arm_gic: Add qdev property for GIC revision
  hw/arm_gic: Make CPU target registers RAZ/WI on uniprocessor
  hw/arm_gic.c: Make NVIC interrupt numbering a runtime setting
  hw/arm_gic: Move CPU interface memory region setup into arm_gic_init
  hw/armv7m_nvic: Make the NVIC a freestanding class
