Currently, BOOKE watchdog code for checking "wdt" and "wdt_period" is
in setup_32.c, it cannot be used in 64-bit, so move it to a common place
setup-common.c, which will be shared by 32-bit and 64-bit.
Also, replace the simple_strtoul with kstrtol.

Freescale PowerPC SoCs share a number of IP blocks with Freescale
ARM/IMX SoCs, FlexCAN, SSI, FEC, eSDHC, USB, etc. There are some
effort consolidating those drivers to make them work for both
architectures.
One outstanding difference between two architectures is ARM/IMX will
turn off module clocks during platform initialization for power saving
and expects drivers manage clocks using clk API, while PowerPC
mostly does not do that, and thus does not always build in clk API.
Listing all those driver Kconfig options in "select PPC_CLOCK if" seems
not scalable for long term maintenance, and could easily introduce
Kconfig recursive dependency. This patch chooses to select PPC_CLOCK
unconditionally for FSL_SOC to always build clk API for PowerPC in.

In order to enable the DIU video controller on the P1022DS, the FPGA needs
to be switched to "indirect mode", where the localbus is disabled and
the FPGA is accessed via writes to localbus chip select signals CS0 and CS1.
To obtain the address of CS0 and CS1, the platform driver uses an "indirect
pixis mode" device tree node. This node assumes that the localbus 'ranges'
property is sorted in chip-select order. That is, reg value 0 maps to
CS0, reg value 1 maps to CS1, etc. This is how the 'ranges' property is
supposed to be arranged.
Unfortunately, the 'ranges' property is often mis-arranged, and not just on
the P1022DS. Linux normally does not care, since it does not program the
localbus. But the indirect-mode code on the P1022DS does care.
The "proper" fix is to have U-Boot fix the 'ranges' property, but this would
be too cumbersome. The names and 'reg' properties of all the localbus
devices would also need to be updated, and determining which localbus device
maps to which chip select is board-specific.
Instead, we determine the CS0/CS1 base addresses the same way that U-boot
does -- by reading the BRx registers directly and mapping them to physical
addresses. This code is simpler and more reliable, and it does not require
a U-boot or device tree change.
Since the indirect pixis device tree node is no longer needed, the node is
deleted from the DTS.

This reference board dates back to 2004, and is largely a legacy
EOL product. The MPC8560 is a pre e500v2 CPU. The SBC8548 is
a more modern, better e500v2 target for people to use as a
reference board with today's kernels, should they require one.
Removing support for it will also allow us to remove some
sbc8560 specific quirk handling in 8250 UART code, and some
MTD mapping support.

This reverts commit 0c00f65653389a408dfbbee7578e671664eea26a.
The initial commit was my fault. There are two boards out there:
P2020RDB and P2020RDB-PC. I wasn't aware of that and assumed that I have
a RDB board in front of me while I the RDB-PC. This patch makes it work
for the RDB-PC variant and breaks it for the RDB. Now there is a device
tree file available for the RDB-PC which was not there earlier. So with
this revert, everything gets back to normal :)

Add the ability to inject IOMMU faults. We enable this per device
via a fail_iommu sysfs property, similar to fault injection on other
subsystems.
An example:
...
0003:01:00.1 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 02)
To inject one error to this device:
echo 1 > /sys/bus/pci/devices/0003:01:00.1/fail_iommu
echo 1 > /sys/kernel/debug/fail_iommu/probability
echo 1 > /sys/kernel/debug/fail_iommu/times
As feared, the first failure injected on the be3 results in an
unrecoverable error, taking down both functions of the card
permanently:

At the moment we always use the SIAR if the PMU supports continuous
sampling. Unfortunately the SIAR and the PMU exception are not
synchronised for non marked events so we can end up with callchains
that dont make sense.
The following patch checks the HV and PR bits for samples coming from
userspace and always uses pt_regs for them. Userspace will never have
interrupts off so there is no real advantage to using the SIAR for
non marked events in userspace.
I had experimented with a patch that did a similar thing for kernel
samples but we lost a significant amount of information. I was
unable to profile any of our early exception code for example.

The logic to choose whether to use the SIAR or get the information
out of pt_regs is going to get more complicated, so do it once in

We overload regs->result which is gross but we are already doing it
