Some chips (like the SoCs from Freescale) report the wrong value in NIRQ
and this causes issues if its doesn't match or exceed the value of
irq_count.
Add a flag that board code can set to just use irq_count instead of
FRR[NIRQ]. Eventually we'll add a device tree property with the number
of sources.

This adds a function to put a 6xx/7xx/7xxx/83xx family CPU into sleep
mode, and return after an interrupt has occurred. It expects to be
called with interrupts disabled, and returns with interrupts disabled.
Interrupts are enabled while the processor is asleep, but the interrupt
that wakes the processor is not handled; it is still pending when this
function returns.

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.

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.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
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
patch later.

The original RapidIO driver suppose there is only one mpc85xx RIO controller
in system. So, some data structures are defined as mpc85xx_rio global, such
as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's
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.

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.

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.
