This patch series adds the initial support for imx6q, which is a
Cortex-A9 Quad Core based SoC.
It's based on v3.1-rc8 with the following branches merged.
* rmk's for-next branch with the following additional patches wait for
rmk to apply:
- ARM: l2x0: add empty l2x0_of_init (Rob Herring)
- ARM: cache-l2x0: add resume entry for l2 in secure mode (Barry Song)
- ARM: localtimer: add header linux/errno.h explicitly (Shawn Guo)
- ARM: smp: Add an IPI handler callable from C code (Marc Zyngier)
- ARM: smp: Add a localtimer handler callable from C code (Shawn Guo)
* Rob Herring's "GIC OF bindings" series, currently on
git://git.jdl.com/software/linux-3.0.git gic-v2
tglx has picked up the two that are irq core related. And I'm not
sure about the branch that Rob will push others to.
* Branches that will be merged into arm-soc
- Sascha's imx-cleanup
- Sascha's imx-features
- [GIT PULL] DEBUG_LL platform updates for 3.2 (Will Deacon)
Regards,
Shawn
Changes since v4:
* Address Russell's comments, do not call do_IPI() and do_local_timer()
from C code.
* Change to 'select AUTO_ZRELADDR if !ZBOOT_ROM'
* Rebase to Barry's L2 suspend infrastructure
* Fold Sascha's merge-imx3-imx6 patch to get single zImage support for
imx3 and imx6 family
Changes since v3:
* Fold the gic_handle_irq (local to imx) support patch in the series.
It can be replaced by Marc Zyngier's global gic_handle_irq support
with a little rework if his PPI and MULTI_IRQ_HANDLER series gets
merged.
Changes since v2:
* Refine the L2 register save/restore implementation per Lorenzo's
suggestion
* Rebase to Rob's latest GIC OF bindings series
* Rebase to Sascha's MULTI_IRQ_HANDLER support series
Changes since v1:
* Use the existing IMX_IO_P2V for static mapping
* Fix the MXC_INTERNAL_IRQS breakage introduced by GIC definition
* Retrieve clock frequency for fixed clocks from device tree
* Drop early_initcall from imx_src_init() and call it from imx6q
platform initialization
* Use readl_relaxed/writel_relaxed rather than __raw_readl/__raw_writel
as suggested by Arnd
* Kill unnecessary imx_local_timer_pre_suspend/resume functions
* Kill Kconfig symbol MACH_IMX6Q
* Rebase to rmk's "Add L2 cache cleaning to generic CPU suspend" series
so that we can retain L2 cache with necessary L2 register
save/restore across suspend/resume cycle
* Rebase to Rob's new "GIC OF bindings" series

To: linux-arm-kernel
From: Sascha Hauer <s.hauer@pengutronix.de>
The patch merges the build of imx3 and imx6. The Kconfig symbol
ARCH_IMX_V6_V7 is introduced to replace ARCH_MX3 and ARCH_MX6.
