      ARM: mvebu: switch the Armada XP DB to use internal registers at 0xf1000000 · 82066bdb
      Thomas Petazzoni authored
      
      
      Marvell has now provided bootloaders that are Device Tree capable for
      the Armada XP DB board, and that also remap the internal register base
      address to 0xf1000000. In addition, the bootloader now sets the MBus
      Window base address to 0xf0000000, but on this board, this change
      doesn't make much difference since the board is by default equipped
      with 2 GB of RAM.
      
      Therefore this commit updates the soc->ranges Device Tree property
      with the fact that the internal registers are now mapped at
      0xf1000000.

      ARM: mvebu: change the default PCIe apertures for Armada 370/XP · 46febc63
      Thomas Petazzoni authored
      
      
      The latest Marvell bootloaders for various boards change the MBus
      Window base address from 0xC0000000 to 0xF0000000, in order to make
      more RAM in the first 4 GB actually usable by the kernel (RAM that is
      covered by the MBus window is "shadowed" and therefore not usable).
      
      However, our default PCIe memory and I/O apertures where sitting at
      0xe0000000 (for memory) and 0xe8000000 (for I/O), which will now be
      outside of the MBus Window range on those platforms. To make things
      work, we have to ensure those apertures use addresses in the
      0xF0000000 -> 0xFFFFFFFF range.
      
      Of course this change of the MBus Window base address from 0xC0000000
      to 0xF0000000 also comes with a change of the internal register base
      address from 0xD0000000 to 0xF1000000.
      
      We have therefore designed the following memory map:
      
       * 0xF0000000 -> 0xF1000000: 16 MB, used for NOR flashes on Armada XP
         GP and Armada XP DB.
      
       * 0xF1000000 -> 0xF1100000: 1 MB, used for internal registers.
      
       * 0xF8000000 -> 0xFFE00000: 126 MB, used for PCIe memory.
      
       * 0xFFE00000 -> 0xFFF00000: 1 MB, used for PCIe I/O.
      
       * 0xFFF00000 -> 0xFFFFFFFF: 1 MB, used for the BootROM mapping
      
      There is one exception to this layout: the Armada XP OpenBlocks, which
      has a 128 MB NOR flash, mapped from 0xF0000000 to 0xF8000000. This
      does not conflict with the current change for the PCIe I/O and memory
      apertures, and continues to work because on Armada XP OpenBlocks, the
      bootloader is an old one, and continues to have internal registers
      mapped at 0xD0000000.

      Pull parisc updates from Helge Deller:
       "The three major changes in this patchset is a implementation for
        flexible userspace memory maps, cache-flushing fixes (again), and a
        long-discussed ABI change to make EWOULDBLOCK the same value as
        EAGAIN.
      
        parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
        to keep HP-UX compatibility.  Since we will probably never implement
        full HP-UX support, we prefer to drop this compatibility to make it
        easier for us with Linux userspace programs which mostly never checked
        for both values.  We don't expect major fall-outs because of this
        change, and if we face some, we will simply rebuild the necessary
        applications in the debian archives"
      
      * 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
