      irq: add irq_domain translation infrastructure · 08a543ad
      Grant Likely authored
      This patch adds irq_domain infrastructure for translating from
      hardware irq numbers to linux irqs.  This is particularly important
      for architectures adding device tree support because the current
      implementation (excluding PowerPC and SPARC) cannot handle
      translation for more than a single interrupt controller.  irq_domain
      supports device tree translation for any number of interrupt
      controllers.
      
      This patch converts x86, Microblaze, ARM and MIPS to use irq_domain
      for device tree irq translation.  x86 is untested beyond compiling it,
      irq_domain is enabled for MIPS and Microblaze, but the old behaviour is
      preserved until the core code is modified to actually register an
      irq_domain yet.  On ARM it works and is required for much of the new
      ARM device tree board support.
      
      PowerPC has /not/ been converted to use this new infrastructure.  It
      is still missing some features before it can replace the virq
      infrastructure already in powerpc (see documentation on
      irq_domain_map/unmap for details).  Followup patches will add the
      missing pieces and migrate PowerPC to use irq_domain.
      
      SPARC has its own method of managing interrupts from the device tree
      and is unaffected by this change.

      This was introduced more than 3 years ago, and since then only generic
      janitorial changes were made without further addition of actual support
      for "real" devices.  This is therefore a cost with no benefits to keep
      in the tree.  If someone wishes to revive this code, it is always
      possible to retrieve it from the Git repository.

      So out it goes as well.
      
      The PORT_S3C2400 definition in include/linux/serial_core.h is left there
      to prevent a reuse of the same number for another port type.

      ARM: Xilinx: Adding Xilinx board support · b85a3ef4
      John Linn authored
      The 1st board support is minimal to get a system up and running
      on the Xilinx platform.
      
      This platform reuses the clock implementation from plat-versatile, and
      it depends entirely on CONFIG_OF support.  There is only one board
      support file which obtains all device information from a device tree
      dtb file which is passed to the kernel at boot time.

      ARM: Allow SoCs to enable scatterlist chaining · 74facffe
      Russell King authored
      Allow SoCs to enable the scatterlist chaining support, which allows
      scatterlist tables to be broken up into smaller allocations.
      
      As support for this feature depends on the implementation details of
      the users of the scatterlists, we can't enable this globally without
      auditing all the users, which is a very big task.  Instead, let SoCs
      progressively switch over to using this.
      
      SoC drivers using scatterlists and SoC DMA implementations need
      auditing before this option can be enabled for the SoC.
