2014-03-21ARM: msm: avoid calling debug_ll_addr on !MMUArnd Bergmann1-0/+2
MSM7X00A has an open-coded version of debug_ll_io_init so it can use MT_DEVICE_NONSHARED as required by the platform. However, this fails to build on no-MMU kernels because the debug_ll_addr function is not available. Since the iotable_init function doesn't actually do anyting in this configuration, we can simply get away by enclosing the broken function call in an #ifdef, which seems to be the least ugly workaround.

2013-08-06ARM: msm: Move mach/board.h contents to common.hStephen Boyd1-2/+1
The contents of mach/board.h are only used by files within mach-msm so there is no need to export this file outside of the mach-msm directory. Move the contents of the file to common.h to allow us to compile MSM in the multi-platform kernel.

2013-08-06ARM: msm: Remove TMR and TMR0 static mappingsStephen Boyd1-26/+0
Nobody is using these mappings so just drop them. of_iomap() in the timer driver will take care of it for us. Doing this allows us to remove the 8x60 and 8960 iomap files completely. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>

Pull ARM updates from Russell King: "This contains the usual updates from other people (listed below) and the usual random muddle of miscellaneous ARM updates which cover some low priority bug fixes and performance improvements. I've started to put the pull request wording into the merge commits, which are: - NoMMU stuff: This includes the following series sent earlier to the list: - nommu-fixes - R7 Support - MPU support I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were discussing today until we've reached a conclusion/that's had some more review. This is rebased (and re-tested) on your devel-stable branch because otherwise there were going to be conflicts with Uwe's V7M work now that you've merged that. I've included the fix for limiting MPU to CPU_V7. - Huge page support These changes bring both HugeTLB support and Transparent HugePage (THP) support to ARM. Only long descriptors (LPAE) are supported in this series. The code has been tested on an Arndale board (Exynos 5250). - LPAE updates Please pull these miscellaneous LPAE fixes I've been collecting for a while now for 3.11. They've been tested and reviewed by quite a few people, and most of the patches are pretty trivial. -- Will Deacon. - arch_timer cleanups Please pull these arch_timer cleanups I've been holding onto for a while. They're the same as my last posting, but have been rebased to v3.10-rc3. - mpidr linearisation (multiprocessor id register - identifies which CPU number we are in the system) This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems.

From David Brown: These patches migrate both the 8660 and 8960 targets on msm to be devicetree only. This also sets most of the frame in place necessary to build both targets into the same image. There's a couple of cleanups in here that are kept in this series because they are intimately tied to the changes necessary to support the devicetree conversions.

2012-09-13ARM: msm: io: Change the default static iomappings to be sharedRohit Vaswani1-9/+13
With 3.4 kernel the static iomappings can be shared with the ioremap mappings. If ioremap is called with an address for which a static mapping already exists, then that mapping should be used instead of creating a new one. However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid of this flag. Some targets (7X00) that require the static iomappings to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.
