7e1cc9c55a powerpc: Fix a bunch of sparse warnings in the qe_lib
Mostly having to do with not marking things __iomem.  And some failure
to use appropriate accessors to read MMIO regs.

4cd7e1cbd4 powerpc: Add support for multiple gfar mdio interfaces
The old code assumed there was only one, but the 8572 actually has 3.

Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was
preventing the multiple buses from having different ids.  So we only keep
the low 20 bits, which have the interesting info, anyway.

a47fda9307 powerpc/86xx: mpc8610_hpcd - add support for ULI RTC
The ULI "Super South Bridge" contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.

i8259 is disabled on the MPC8610HPCD, and other peripherals are not
traced out. So we use only RTC.

52ddd1cdc9 powerpc/85xx/86xx: some refactoring for fsl_uli1575 code
- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
  Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
  machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

00c5372d37 powerpc/fsl_uli1575: fix RTC quirk to work on MPC8572DS and MPC8610HPCD
This patch fixes RTC on MPC8572DS boards: dummy read helps only when
reading at the end of the bridge's memory (i.e. outside of behind the
bridge devices' assigned regions).

With this change the quirk also makes RTC work on MPC8610HPCD, so it's
unlikely that this will break MPC8641HPCN or MPC8544DS boards.

69ad7e73de powerpc/fsl_soc: gianfar: don't probe disabled devices
Freescale ships MPC8315E-RDB boards in two variants:

1. With TSEC1 ethernet support and USB UTMI PHY;
2. Without TSEC1 support, but with USB ULPI PHY in addition.

For the second case U-Boot will add status = "disabled"; property
into the TSEC1 node, so Linux should not try to probe it.

b500563b22 powerpc: pci config cleanup
Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression.  This
patch makes this easier by changing:
    bool "PCI support" if <long expression>
to
    bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.

Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

36aa7965d8 powerpc/mpc7448: add alias list to DTS, clean out old chosen node
The mpc7448hpc2 board doesn't have an alias block like
most of the other modern eval boards have.  We need this
block in order to have u-boot be able to make use of the
CONFIG_OF_STDOUT_VIA_ALIAS (vs. having a hard coded node)
in the future.

Also remove the old, redundant chosen node.  Of all the modern
Freescale eval boards (incl. 83xx, 85xx, 86xx) this is the only
one which still has it.  Its presence also breaks with some older
versions of u-boot, like 1.3.1 -- which try and insert a
second chosen node.

0f47331475 powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPAT
Background from Maynard Johnson:
As of POWER6, a set of 32 common events is defined that must be
supported on all future POWER processors.  The main impetus for this
compat set is the need to support partition migration, especially from
processor P(n) to processor P(n+1), where performance software that's
running in the new partition may not be knowledgeable about processor
P(n+1).  If a performance tool determines it does not support the
physical processor, but is told (via the
PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports
the notion of the PMU compat set, then the performance tool can
surface just those events to the user of the tool.

PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at
least this basic subset of events which is compatible across POWER
processor lines.

4df64c3e58 powerpc/mpc5121: Update device tree for MPC5121ADS evaluation board
Current device tree is only bare bones.  This patch adds nodes to make
it a complete tree for the MPC5121ads.

Added nodes include:
    mbx      - opengl coprocessor
    nfc      - nand flash controller
    cpld-pic - on board cpld
    rtc
    clock    - clock control
    pmc      - power management control
    gpio
    mscan    - can module
    i2c
    axe      - audio coprocessor
    display  - display interface unit
    mdio
    ethernet
    usb
    ioctl    - pin config
    pata
    ac97     - PSC configured as AC97
    pscfifo  - psc fifo configuration
    dma
    pci

Fix typo in header changing MDS to ADS.

Add a compatible property of the form "fsl,mpc5121-..."
to nodes missing one.

Changed localbus compatible to fsl,mpc5121-localbus, this does
not break anything because the only code that uses it finds it
via the node name, not compatible.

7ba6d6dc8d powerpc/mpc5200: Add PSC helpers for bestcomm engine
Simplify the interface for setting up bestcomm DMA to PSCs by adding
some helper functions.  The helper function sets the correct values
for the initator and ipr values in PSC DMA tasks based on the PSC
number.
