Update p1022 sata compatible to "fsl,p1022-sata", "fsl,pq-sata-v2".
p1022ds sata controller is v2 version comparing previous FSL sata
controller, for example, mpc8536.

In FSL sata v2 block, the snoop bit of PRDT Word3 description
information is at bit28 instead of bit22.

This patch adds FSL sata v2 probe and resolve this difference.

Commit da3ed89e added
'fsl,qoriq-gpio' compatiable searching in the old way
using for_each_compatible_node(). But the driver have
previously been changed to use a struct of_device_id
compatible list passed to for_each_matching_node().

Add 'fsl,qoriq-gpio' compatiable to the existing
compatible list instead of adding another
for_each_compatible_node() loop.

The MPC852 based mgsuvd board from Keymile was initially ported,
but later on not developed further. This patch removes the respective
files to decrease merging conflicts and unneeded maintenance.

The mgcoge board from keymile is now base for some other
similar boards. Therefore the board specific name mgcoge
was renamed to a generic name km82xx. Additionally some
enhancements were made:
	- rework partition table in dts file
	- add cpm2_pio_c gpio controller in dts file
	- update defconfig
	- add pin description for SCC1
	- add pin description and configuration for USB

Beside the MPC 8360 based board kmeter1 other km83xx boards
from keymile will follow. Therefore the board specific naming
kmeter1 for functions and files were replaced with km83xx.
Additionally some updates were made:
    - update defconfig for 2.6.38
    - rework flash partitioning in dts file
    - add gpio controller for qe_pio_c in dts

This erratum can occur if a single-precision floating-point,
double-precision floating-point or vector floating-point instruction on a
mispredicted branch path signals one of the floating-point data interrupts
which are enabled by the SPEFSCR (FINVE, FDBZE, FUNFE or FOVFE bits).  This
interrupt must be recorded in a one-cycle window when the misprediction is
resolved.  If this extremely rare event should occur, the result could be:

The SPE Data Exception from the mispredicted path may be reported
erroneously if a single-precision floating-point, double-precision
floating-point or vector floating-point instruction is the second
instruction on the correct branch path.

According to errata description, some efp instructions which are not
supposed to trigger SPE exceptions can trigger the exceptions in this case.
However, as we haven't emulated these instructions here, a signal will
send to userspace, and userspace application would exit.

This patch re-issue the efp instruction that we haven't emulated,
so that hardware can properly execute it again if this case happen.

FSL PCIe controller v2.1:
     - New MSI inbound window
     - Same Inbound windows address as PCIe controller v1.x

Added new pit_t member(pmit) to struct ccsr_pci for MSI inbound window

FSL PCIe controller v2.2 and v2.3:
     - Different addresses for PCIe inbound window 3,2,1
     - Exposed PCIe inbound window 0
     - New PCIe interrupt status register

Added new config and interrupt Status register to struct ccsr_pci & updated
pit_t array size to reflect the 4 inbound windows.

Device tree is used to maintain backward compatibility i.e. update inbound
window 1 index depending upon "compatible" field witin PCIE node.

If the spin table is located in the linear mapping (which can happen if
we have 4G or more of memory) we need to access the spin table via a
cacheable coherent mapping like we do on ppc32 (and do explicit cache
flush).

See the following commit for the ppc32 version of this issue:

    powerpc/85xx: Fix SMP when "cpu-release-addr" is in lowmem
Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

On upcoming hardware, we have a PCI adapter with two functions, one of
which uses MSI and the other uses MSI-X. This adapter, when MSI is
disabled using the "old" firmware interface (RTAS_CHANGE_FN), still
signals an MSI-X interrupt and triggers an EEH. We are working with the
vendor to ensure that the hardware is not at fault, but if we use the
"new" interface (RTAS_CHANGE_MSI_FN) to disable MSI, we also
automatically disable MSI-X and the adapter does not appear to signal
any stray MSI-X interrupt.

If firmware allows us to map all of a partition's memory for DMA on a
particular bridge, create a 1:1 mapping of that memory. Add hooks for
dealing with hotplug events. Dynamic DMA windows can use larger than the
default page size, and we use the largest one possible.
