Subject[PATCH v7 00/13] ARM: vf610m4: Add Vybrid Cortex-M4 support
Beside the additional helper irq_chip_(enable|disable)_parent
I also cleaned up Kconfig.debug by adding ARM_SINGLE_ARMV7M as
that each ARMv7-M ARCH_/SOC_ needs to be added.

Shawn, if ok, could you pickup that patchset as Arnd suggested?
I guess the IRQ stuff still should go through Jason's tree
directly (Patch 1-5)?

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

Note: The patch "ARM: ARMv7M: define size of vector table for
Vybrid" has a dependency on "ARM: ARMv7-M: Enlarge vector table
up to 256 entries" (Maxime Coquelin), which is in Russels patch
system (marked as applied, see 8340/1). However, since the
vector table defaults to 240 with that patch, defining the size
of the vector table for Vybrid is not absolutely required.
Therefor patch 6 can also be applied at a later point in time...

Changes since v6:
- Add genirq irq_chip_(enable|disable)_parent helper
since all supported ARMv7-M platforms so far support early
debug through DEBUG_LL

Changes since v5:
- Remove unnecessary empty lines in Kconfig
- Add non-hierarchy helper irq_domain_set_info
- Rebased on v4.1-rc1

Changes since v4:
- Added ARM_SINGLE_ARMV7M as top-level config symbol for ARMv7-M
- Cleaned up unnecessary selects within SOC_VF610
- Added linux,stdout-path to device tree

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:

Stefan Agner (13):
irqdomain: Add non-hierarchy helper irq_domain_set_info
genirq: Add irq_chip_(enable|disable)_parent
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: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms
ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC
ARM: dts: add support for Vybrid running on Cortex-M4
ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4
