Subject[PATCH v4 00/11] ARM: vf610m4: Add Vybrid Cortex-M4 support
The fourth version has one small fix in the MSCM IR driver and
one dependency fix.

Like version 3 of the patchset, it does not contain the interrupt
router driver anymore (MSCM IR). The driver has been merged

This patchset extends the NVIC driver to support irq domain
hierarchy and the MSCM IR driver to support NVIC as a parent irq

I'm happy with the outcome of the MSCM driver, the irq domain
hierarchy support has proven to work with GIC and NVIC as

Since v2, this patchset also doesn't add any ARCH or SOC anymore.
Instead, it allows to select ARCH_MULTIPLATFORM in the !MMU case
and add ARCH_MULTI_V7M as a new CPU choice. This change is based
on patches found in Arnd's git tree, however, it tries to allow
MULTIPLATFORM with !MMU in a way which should not allow to make
other selections than before (except ARCH_MULTI_V7M of course).
This makes ARCH_MXC and SOC_VF610 available for the !MMU CPU V7M.
With a small change, SOC_VF610 is now selectable when the CPU
ARCH_MULTI_V7M is selected, and hence allows to build a kernel
for the Cortex-M4 CPU too.

The patchset has proven to be working on the Cortex-M4 of the
Vybrid SoC using a Colibri VF61 module.

Changes since v3:
- Added dependency IRQ_DOMAIN_HIERARCHY for ARM_NVIC
- Fix MSCM IR disable function check
- Remove "ARM: imx: depend MXC debug board on 3DS machines",
the patch has been merged

Changes since v2:
- Update MSCM patches to merged version of MSCM interrupt router
- Use the GPLv2/X11 dual license in the new device tree files
- Drop SD controller in device tree (initramfs works now and is
probably more appropriate for most cases)
- Disable GPIO nodes since the A5 is using them
- Drop CONFIG_ prefixes in Kconfig changes for MXC_DEBUG_BOARD
- Drop vector table resizing in favor of Maxime Coquelin's patch
- Remove !MMU dependency for ARCH_EFM32 since its part of
- Rebased on v4.0-rc1

Changes since v1:
- Remove MSCM driver
- Support irq domain hierarchy with NVIC irq controller
- Extend MSCM interrupt router with NVIC as parent in the irq
domain hierarchy
- Rebased on v3.19-rc1 with MSCM driver
- NVIC: Register only the amount of IRQ's which vectors are
available for

Changes since RFC:
- Unified addruart calls for MMU/!MMU
- Add MSCM support along with routable IRQ support in NVIC
- Rebased on Shawns for-next tree which made some changes
obsolete (mainly the Vybrid SoC device tree files in for-next
are already prepared for Cortex-M4 support)
- Removed SRC_GPR3 hack, this is now part of a mini boot-loader:

Arnd Bergmann (1):
ARM: efm32: move into multiplatform

Stefan Agner (10):
genirq: generic chip: support hierarchy domain
irqchip: nvic: support hierarchy irq domain
irqchip: vf610-mscm: support NVIC parent
ARM: ARMv7M: define size of vector table for Vybrid
clocksource: add dependencies for Vybrid pit clocksource
ARM: unify MMU/!MMU addruart calls
ARM: vf610: enable Cortex-M4 on Vybrid SoC
ARM: dts: add support for Vybrid running on Cortex-M4
ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4
