Subject: [PATCH v7 00/13] ARM: vf610m4: Add Vybrid Cortex-M4 support
Date: Sat, 16 May 2015 11:44:12 +0200 [thread overview]
Message-ID: <1431769465-26867-1-git-send-email-stefan@agner.ch> (raw)
Beside the additional helper irq_chip_(enable|disable)_parent
I also cleaned up Kconfig.debug by adding ARM_SINGLE_ARMV7M as
UNCOMPRESS_INCLUDE/DEBUG_UNCOMPRESS dependencies. This avoids
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
- Add ARM_SINGLE_ARMV7M to UNCOMPRESS_INCLUDE/DEBUG_UNCOMPRESS
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
architectures
- 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
(https://lkml.org/lkml/2015/2/20/399)
- Remove !MMU dependency for ARCH_EFM32 since its part of
ARCH_MULTI_V7M
- 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:
