    powerpc/pseries: Return the number of MSIs we could allocate

    If we can't allocate the requested number of MSIs, we can still tell the
    generic code how many we were able to allocate. That can then be passed
    onto the driver, allowing it to request that many in future, and
    probably succeeed.

    powerpc: Allow debugging of LMBs with lmb=debug

    The lmb debugging can be turned on at boottime with lmb=debug on the
    command line. However on powerpc that doesn't work, because we don't
    necessarily call lmb_dump_all().

    So always call lmb_dump_all() after lmb_analyze(), no output is
    generated unless lmb=debug is found on the command line.

    powerpc/5200: Rework GPT driver to also be an IRQ controller

    This patch adds IRQ controller support to the MPC5200 General
    Purpose Timer (GPT) device driver.  With this patch the mpc5200-gpt
    driver supports both GPIO and IRQ functions.

    The GPT driver was contained within the mpc52xx_gpio.c file, but this
    patch moves it out into a new file (mpc52xx_gpt.c) since it has more
    than just GPIO functionality now and it was only grouped with the
    mpc52xx-gpio drivers as a matter of convenience before.  Also, this
    driver will most likely get extended again to also provide support
    for the timer function.

    Implementation note: Alternately, I could have tried to implement
    the IRQ support as a separate driver and left the GPIO portion alone.
    However, multiple functions of this device (ie. GPIO input+interrupt
    controller, or timer+GPIO) can be active at the same time and the
    registers are shared so it is safer to contain all functionality
    within a single driver.

    Rework the mpc5200-pic driver to simplify it and fix up the setting
    of desc->status when set_type is called for internal IRQs (so they
    are reported as level, not edge).  The simplification is due to
    splitting off the handling of external IRQs into a separate block
    so they don't need to be handled as exceptions in the normal
    CRIT, MAIN and PERP paths.

    madness.  Editorial changes were made to keep the all the
    mpc5200 board device trees as similar as possible so that diffs
    between them only show the real differences between the boards.
    The pcm030 device tree was most affected by this because many
    of the comments had been changed from // to /* */ style and
    some cell values where changed from decimal to hex format when
    it was cloned from one of the other 5200 device trees.

    powerpc/5200: Stop using device_type and port-number properties

    There is no reason for the PSC UART driver or the Ethernet driver
    to require a device_type property.  The compatible value is sufficient
    to uniquely identify the device.  Remove it from the driver.

    The whole 'port-number' scheme for assigning numbers to PSC uarts was
    always rather half baked and just adds complexity.  Remove it from the
    driver.  After this patch is applied, PSC UART numbers are simply
    assigned from the order they are found in the device tree (just like
    all the other devices).  Userspace can query sysfs to determine what
    ttyPSC number is assigned to each PSC instance.

    powerpc/fsl-booke: Make CAM entries used for lowmem configurable

    Make this number configurable in the advanced options menu along with max

    powerpc/fsl-booke: Allow larger CAM sizes than 256 MB

    The code that maps kernel low memory would only use page sizes up to 256
    MB.  On E500v2 pages up to 4 GB are supported.

    However, a page must be aligned to a multiple of the page's size.  I.e.
    256 MB pages must aligned to a 256 MB boundary.  This was enforced by a
    requirement that the physical and virtual addresses of the start of lowmem
    be aligned to 256 MB.  Clearly requiring 1GB or 4GB alignment to allow
    pages of that size isn't acceptable.

    To solve this, I simply have adjust_total_lowmem() take alignment into
    account when it decides what size pages to use.  Give it PAGE_OFFSET =
    0x7000_0000, PHYSICAL_START = 0x3000_0000, and 2GB of RAM, and it will map
    pages like this:
    PA 0x3000_0000 VA 0x7000_0000 Size 256 MB
    PA 0x4000_0000 VA 0x8000_0000 Size 1 GB
    PA 0x8000_0000 VA 0xC000_0000 Size 256 MB
    PA 0x9000_0000 VA 0xD000_0000 Size 256 MB
    PA 0xA000_0000 VA 0xE000_0000 Size 256 MB

    Because the lowmem mapping code now takes alignment into account,
    PHYSICAL_ALIGN can be lowered from 256 MB to 64 MB.  Even lower might be
    possible.  The lowmem code will work down to 4 kB but it's possible some of
    the boot code will fail before then.  Poor alignment will force small pages
    to be used, which combined with the limited number of TLB1 pages available,
    will result in very little memory getting mapped.  So alignments less than
    64 MB probably aren't very useful anyway.

    powerpc/fsl-booke: Remove code duplication in lowmem mapping

    The code to map lowmem uses three CAM aka TLB[1] entries to cover it.  The
    size of each is stored in three globals named __cam0, __cam1, and __cam2.
    All the code that uses them is duplicated three times for each of the three
    variables.

    We have these things called arrays and loops....

    Once converted to use an array, it will be easier to make the number of
    CAMs configurable.

    powerpc/fsl-booke: Cleanup init/exception setup to be runtime

    We currently have a few variants of fsl-booke processors (e500v1, e500v2,
    e500mc, and e200).  They all have minor differences that we had previously
    been handling via ifdefs.

    To move towards having this support the following changes have been made:

    * PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on
      e500mc or e200.  We use MMUCFG[NPIDS] to determine which case we are
      since we only touch PID1/2 in extremely early init code.

    * Not all IVORs exist on all the processors so introduce cpu_setup
      functions for each variant to setup the proper IVORs that are either
      unique or exist but have some variations between the processors

    powerpc/83xx: Add PCI-E support for all MPC83xx boards with PCI-E

    This patch adds pcie nodes to the appropriate dts files, plus adds
    some probing code for the boards.

    Also, remove of_device_is_avaliable() check from the mpc837x_mds.c
    board file, as mpc83xx_add_bridge() has the same check now.

    powerpc/fsl_pci: Add MPC83xx PCI-E controller RC mode support

    This patch adds support for PCI-Express controllers as found on the
    newer MPC83xx chips.

    The work is loosely based on the Tony Li's patch[1], but unlike the
    original patch, this patch implements sliding window for the Type 1
    transactions using outbound window translations, so we don't have to
    ioremap the whole PCI-E configuration space.
