This converts the Integrator platform to use common clock and the ICST driver. Since from this point not all ARM reference platforms use the clock, we define CONFIG_PLAT_VERSATILE_CLOCK and select it for all platforms except the Integrator. Open issue: I could not use the .init_early() field of the machine descriptor to initialize the clocks, but had to move them to .init_irq(), so presumably .init_early() is so early that common clock is not up, and .init_machine() is too late since it's needed for the clockevent/clocksource initialization. Any suggestions on how to solve this is very welcome.

This patch allows the ATAG_CMDLINE provided by the bootloader to be concatenated to the bootargs property of the device tree. This is useful to merge static values defined in the device tree with the boot loader's (possibly) more dynamic values, such as startup reasons and more. The bootloader should use the device tree to pass those values to the kernel, but that's not always simple (old bootloader or very small one). The behaviour is the same as the one introduced by Victor Boivie in 4394c124 by extending the CONFIG_CMDLINE.

As all irqchips on imx have been changed to allocate their irq_descs, and all unneeded mach/irqs.h inclusions on imx have been cleaned up, now it's time to select SPARSE_IRQ for imx/mxc. The SPARSE_IRQ support forces irqs allocation starting from 16. All those static irq number definition for SoCs need to shift 16 to keep non-DT boot works. With all those static IRQ number and start definitions removed from mach/irqs.h, the header becomes just a container of a couple of mach-imx specific irq/fiq calls. Since mach/irqs.h is not included by asm/irq.h now, the users of mxc_set_irq_fiq needs to explicitly include mach/irqs.h themselves.

Commit 4d5fc58d (ARM: remove bunch of now unused mach/io.h files) removed the orion5x io.h. Unfortunately, this is still needed for the definition of IO_SPACE_LIMIT which overrides the default 64K. All Orion based systems have 1Mbyte of IO space per PCI[e] bus, and try to request_resource() this size. Orion5x has two such PCI buses. It is likely that the original, removed version, was broken. This version might be less broken. However, it has not been tested on hardware with a PCI card, let alone hardware with a PCI card with IO capabilities.

With commit 4d5fc58d (ARM: remove bunch of now unused mach/io.h files), the I/O space setup was completely broken on versatile. This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.

Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

This patch adds support for CMA to dma-mapping subsystem for ARM architecture. By default a global CMA area is used, but specific devices are allowed to have their private memory areas if required (they can be created with dma_declare_contiguous() function during board initialisation). Contiguous memory areas reserved for DMA are remapped with 2-level page tables on boot. Once a buffer is requested, a low memory kernel mapping is updated to to match requested memory access type. GFP_ATOMIC allocations are performed from special pool which is created early during boot. This way remapping page attributes is not needed on allocation time. CMA has been enabled unconditionally for ARMv6+ systems.

This patch add a complete implementation of DMA-mapping API for devices which have IOMMU support. This implementation tries to optimize dma address space usage by remapping all possible physical memory chunks into a single dma address space chunk. DMA address space is managed on top of the bitmap stored in the dma_iommu_mapping structure stored in device->archdata. Platform setup code has to initialize parameters of the dma address space (base address, size, allocation precision order) with arm_iommu_create_mapping() function. To reduce the size of the bitmap, all allocations are aligned to the specified order of base 4 KiB pages. dma_alloc_* functions allocate physical memory in chunks, each with alloc_pages() function to avoid failing if the physical memory gets fragmented. In worst case the allocated buffer is composed of 4 KiB page chunks. dma_map_sg() function minimizes the total number of dma address space chunks by merging of physical memory chunks into one larger dma address space chunk. If requested chunk (scatter list entry) boundaries match physical page boundaries, most calls to dma_map_sg() requests will result in creating only one chunk in dma address space. dma_map_page() simply creates a mapping for the given page(s) in the dma address space. All dma functions also perform required cache operation like their counterparts from the arm linear physical memory mapping version.
