683307da07 [POWERPC] Create of_buses for MV64x60 devices
For each mv64360 entry in the OpenFirmware database, add the
registration of an of_bus to take care of devices connected to
the MV64x60 asynchronous devices controller.
This change makes it possible for those devices to be detected by
drivers that support the of_platform without having a custom call
for each of them in the board file.

80daac3f86 [POWERPC] 4xx: Add endpoint support to 4xx PCIe driver
This patch adds basic endpoint support to the 4xx PCIe driver.

This is done by checking the device_type property of the PCIe
device node ("pci" for root-complex and "pci-endpoint" for endpoint
configuration).

Note: Currently we map a fixed 64MByte window to PLB address 0 (SDRAM).
This should probably be configurable via a dts property.

Update most new-style i2c drivers to use standard module aliasing

left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own

private members.  And you can define multi RIO OF-nodes in dts file for multi
RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in
Freescale's silicon.  And the mport operation function declaration should be
changed to know which RapidIO controller is target.

30afcb4bd2 return pfn from direct_access, for XIP
Alter the block device ->direct_access() API to work with the new
get_xip_mem() API (that requires both kaddr and pfn are returned).

Some architectures will not do the right thing in their virt_to_page() for use
by XIP (to translate from the kernel virtual address returned by
direct_access(), to a user mappable pfn in XIP's page fault handler.

However, we can't switch it to just return the pfn and not the kaddr, because
we have no good way to get a kva from a pfn, and XIP requires the kva for its
read(2) and write(2) handlers.  So we have to return both.

a0916bd64a [POWERPC] mv643xx_eth: Prepare to support multiple silicon blocks
The mv643xx_eth driver is being modified to support multiple instances
of the ethernet silicon block on the same platform.  Each block contains
a single register bank containing the registers for up to three ports
interleaved within that bank.  This patch updates the PowerPC OF to
platform_device glue code to support multiple silicon blocks, each
with up to three ethernet ports.  The main difference is that we now
allow multiple mv64x60_shared platform_devices to be registered and
we provide each port platform_device with a pointer to its associated
shared platform_device.  The pointer will not be used until the
mv643xx_eth driver changes are committed.

a1810b44c2 [POWERPC] mv64x60: Fix FDT compatible names: mv64x60 => mv64360
Compatible names should refer to a specific version of the hardware,
without wildcards.  Change each instance of mv64x60 to mv64360, which
is the oldest version we currently support.

7132799b0e [POWERPC] kexec: MPIC ack interrupts at mpic_teardown_this_cpu()
We really need to ack interrupts at mpic_teardown, since
not all platforms reset mpic at kernel start-up. For example,
kexec'ed kernel hangs on P.A. Semi if mpic_eoi() isn't called.

93173ce272 [POWERPC] 4xx: Create common ppc4xx_reset_system() in ppc4xx_soc.c
This patch creates a common system reset routine for all 40x and 44x
systems. Previously only a 44x routine existed. But since this system
reset via the debug control register is common for 40x and 44x let's
share this code for all those platforms in ppc4xx_soc.c.

This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms.

Tested on Kilauea (405EX) and Canyonlands (440EX).

5f91925c89 [POWERPC] 4xx: Fix PESDRn_UTLSET1 register setup on 460EX/GT
The patch fixes a bug, where the PESDRn_UTLSET1 register was setup
wrongly resulting in a non working PCIe port 1. With this fix both
PCIe ports work fine again.

b64c4c937d [POWERPC] 4xx: Only reset PCIe PHY on 405EX systems when no link is detected
Since the arch/powerpc PCI subsystem now does a complete re-assignment of
the resources, we can move from the unconditional PCIe PHY reset to the
conditional version. Now the PHY is only reset, if no link is established yet.
An additional PHY reset (one is already done in U-Boot) leads to problems
with some Atheros PCIe boards and some HP FPGA PCIe designs.

2a7069190e [POWERPC] 4xx: Add PPC4xx L2-cache support (440GX)
This patch adds support for the 256k L2 cache found on some IBM/AMCC
4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c)
which currently "only" adds the L2 cache init code. Other common 4xx
stuff can be added later here.

The L2 cache handling code is a copy of Eugene's code in arch/ppc
with small modifications.

Tested on AMCC Taishan 440GX.

66b7e504c0 [POWERPC] 4xx: Add 460EX PCIe support to 4xx pci driver
All this code is needed to properly initialize the 460EX PCIe host
bridge(s). We re-initialize all ports again, even though this has been done
in the bootloader (U-Boot) before. This way we make sure, that we always
run the latest init code in Linux and don't depend on code versions from
U-Boot.

Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need
a different reset-/init-sequence.

Tested on AMCC Canyonlands eval board.
