14f966e794 powerpc/pseries: CMO unused page hinting
Adds support for the "unused" page hint which can be used in shared
memory partitions to flag pages not in use, which will then be stolen
before active pages by the hypervisor when memory needs to be moved to
LPARs in need of additional memory.  Failure to mark pages as 'unused'
makes the LPAR slower to give up unused memory to other partitions.

This adds the kernel parameter 'cmo_free_hint' to disable this
functionality.

d69a78d7da powerpc/mpic: Cleanup mpic_find() implementation
mpic_find() was overloaded to do two things, finding the mpic instance
for a given interrupt and returning if it's an IPI. Instead we introduce
mpic_is_ipi() and simplify mpic_find() to just return the mpic instance

Also silences the warning:

805e324b7f powerpc: Update Warp to use leds-gpio driver
Now that leds-gpio is a proper OF platform driver, the Warp can use
the leds-gpio driver rather than the old out-of-kernel driver.

One side-effect is the leds-gpio driver always turns the leds off
while the old driver left them alone. So we have to set them back to
the correct settings.

54c181935d powerpc/fsl: Setup PCI inbound window based on actual amount of memory
Previouslly we just always set the inbound window to 2G.  This was
broken for systems with >2G.  If a system has >=4G we will need
SWIOTLB support to handle that case.

We now allocate PCICSRBAR/PEXCSRBAR right below the lowest PCI outbound
address for MMIO or the 4G boundary (if the lowest PCI address is above
4G).

01af9507ff powerpc/85xx: Add P2020DS board support
The P2020 is a dual e500v2 core based SOC with:
* 3 PCIe controllers
* 2 General purpose DMA controllers
* 2 sRIO controllers
* 3 eTSECS
* USB 2.0
* SDHC
* SPI, I2C, DUART
* enhanced localbus
* and optional Security (P2020E) security w/XOR acceleration

The p2020 DS reference board is pretty similar to the existing MPC85xx
DS boards and has a ULI 1575 connected on one of the PCIe controllers.

558ab30890 powerpc/8xxx: Update PCI outbound window addresses for 36-bit configs
In these configuration we expect to have large amounts of memory (> 4G)
and thus will bounce via swiotlb some region of PCI address space.

The outbound windows were wasting 512M of address space by leaving a
gap between the top of the outbound window and the 4G boundary.  By
moving the top of the outbound window up to the 4G boundary we can
reclaim the vast majority of the 512M (minus space needed for PEXCSRBAR)
and thus reduces the amount of memory we have to bounce.
