* ARM: integrator: localize the hardware.h headerLinus Walleij2014-02-26
| | | | | | | | | | | | As we move toward multiplatform support for the Integrator family we need to localize all <mach/*> headers. This moves the hardware.h header down to the machine folder. There are no users outside the machine in the kernel.

* ARM: integrator: merge platform.h to hardware.hLinus Walleij2014-02-26
| | | | | | | | | | | | There is no need to have the two separate headers <mach/platform.h> and <mach/hardware.h>, especially since we are now going to make them local files. There is not one single driver outside the mach-integrator folder referencing any of the files.

| * of/irq: Rename of_irq_map_* functions to of_irq_parse_*Grant Likely2013-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF irq handling code has been overloading the term 'map' to refer to both parsing the data in the device tree and mapping it to the internal linux irq system. This is probably because the device tree does have the concept of an 'interrupt-map' function for translating interrupt references from one node to another, but 'map' is still confusing when the primary purpose of some of the functions are to parse the DT data. This patch renames all the of_irq_map_* functions to of_irq_parse_* which makes it clear that there is a difference between the parsing phase and the mapping phase. Kernel code can make use of just the parsing or just the mapping support as needed by the subsystem. The patch was generated mechanically with a handful of sed commands.

* ARM: integrator: basic PCIv3 device tree supportLinus Walleij2013-06-15
| | | | | | | | | | | | | | | | | This registers the memory ranges for I/O, non-prefetched and prefetched memory and configuration space for the PCIv3 bridge and let us fetch these basic memory resources from the device tree in the device tree boot path. Remove the stepping stone platform device. This is an either/or approach - the platform data path is mutually exclusive to the plain platform data path and provided addresses from the device tree have to be correct. This adds the interrupt-map property to the PCIv3 DTS file and makes the bridge obtain mappings from the device tree.

* ARM: integrator: merge PCIv3 driver into one fileLinus Walleij2013-06-03
| | | | | | | | | | | | | | | | | | The Integrator/AP PCI bridget, "v3" is contained in two files, where pci.c is a socket container to plug in the v3 device. However to transition the v3 to enable device tree probing, it need to be converted to a platform device (so that it can have a device node in the device tree) and then we want the PCI driver in a single file, as any other device driver, so we can handle variants using compatible strings and device name, and get the base address etc from resources connected to the device node. To move toward this goal we consolidate all code in the pci_v3.c file. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* ARM: integrator: push down SC dependenciesLinus Walleij2012-11-17
| | | | | | | | | | | | | | | | | | | | | | This pushes the dependencies on the Integrator/AP system controller (SC) down into the PCI V3 driver and the AP-specific board file. First, the platform data for the PL010 UART is moved into the integrator_ap.c board file, and the Integrator/CP is assigned with NULL pdata. This way the callback functions can reference the dynamically remapped AP syscon address in both the ATAG and DT boot path, and this remapping is localized to the board file. Second the PCIv3 driver is making its own dynamic remapping of the SC for the few registers it is using. When we convert the PCIv3 driver over to using device tree having a dynamically assigned base address will be useful, but we will have to use the definition from <mach/platform.h> for now, the only improvement is that it's done dynamically.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis."

I appears that this is due to the VGA base address being assigned at PCI init time, while this base is needed earlier than that. Moving the initialization of the base address to the .map_io function solves this problem.

* ARM: convert PCI defines to variablesRob Herring2011-07-12
| | | | | | | | | | | | | | Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow multi-platform builds. This also removes the requirement for a platform to have a mach/hardware.h. The default values for i/o and mem are 0x1000 and 0x01000000, respectively. Per Arnd Bergmann, other values are likely to be incorrect, but this commit does not try to address that issue.

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
