The mux framework allows the change of pad configuration by drivers
when needed. Prior to this the mux framework has to be initialised
with all the mux parameters specific to the board. The mux init is
already present in the board file for SDP. Adding the mux init
for panda boards.

Please note that the full muxmodes are re-defined for ES2 instead
of using the subset. There are 81 differences among 204 pins.
The subset fixup will have to iterate over the whole list for each
subset entry, which can lead to an important number of iteration.
On the other hand, it will take much more memory at boot time.

Starting on OMAP4, the pin mux configuration is located in two
different partitions of the control module (CODE_PAD and WKUP_PAD).
The first one is inside the core power domain whereas the second
one is inside the wakeup.
- Add the capability to add any number of partition during board init
time depending of Soc partitioning.
- Add some init flags as well in order to avoid explicit Soc version
check inside the mux core code.
- Add a comment with mux0 mode on top of omap_mux/board/<partition>
if the current mux mode is not the default one.
Thanks to Tony Lindgren <tony@atomide.com> for the following improvements:
- Add omap_mux_get for getting the partition data so platform level
device code can use it.
- Fix the rx51 board code to use the new API.
- Do not store the partition for each mux entry. Look up the partition
for debugfs instead.
Thanks to Dan Murphy <dmurphy@ti.com> for testing on OMAP4 and reporting
a couple of bugs.
Thanks to Anand Gadiyar <gadiyar@ti.com> for testing on OMAP3 zoom and

Software generated interrupts (SGI) are used for IPIs by the kernel.
While previous revisions of the GIC hardware were specified not to
implement enable bits for SGIs, more recent hardware is now permitted
to implement these bits in a per-CPU banked register.
The priority registers for the PPI and SGIs are also per-CPU banked
registers, so ensure that these are also appropriately initialized.

Some BIOSes provide PCI host bridge windows that overlap, e.g.,
pci_root PNP0A03:00: host bridge window [mem 0xb0000000-0xffffffff]
pci_root PNP0A03:00: host bridge window [mem 0xafffffff-0xdfffffff]
pci_root PNP0A03:00: host bridge window [mem 0xf0000000-0xffffffff]
If we simply insert these as children of iomem_resource, the second window
fails because it conflicts with the first, and the third is inserted as a
child of the first, i.e.,
b0000000-ffffffff PCI Bus 0000:00
f0000000-ffffffff PCI Bus 0000:00
When we claim PCI device resources, this can cause collisions like this
if we put them in the first window:
pci 0000:00:01.0: address space collision: [mem 0xff300000-0xff4fffff] conflicts with PCI Bus 0000:00 [mem 0xf0000000-0xffffffff]
Host bridge windows are top-level resources by definition, so it doesn't
make sense to make the third window a child of the first. This patch
coalesces any host bridge windows that overlap. For the example above,
the result is this single window:
pci_root PNP0A03:00: host bridge window [mem 0xafffffff-0xffffffff]
This fixes a 2.6.34 regression.

We already deliberately setup a 1-1 P2M for the region up to 1M in
order to allow code which assumes this region is already mapped to
work without having to convert everything to ioremap.
Domain 0 should not return any apparently unused memory regions
(reserved or otherwise) in this region to Xen since the e820 may not
accurately reflect what the BIOS has stashed in this region.

In commit bde28b84, I made the assumption that CONFIG_SMP is always set
for the quad-core ct-ca9x4 platform. As it turns out, people who aren't
using the SMP goodness are confronted with a build failure.
This patch fixes this issue by ensure that twd_base is only set if
local timers are being used (and therefore SMP support is configured).

native_apic_msr_read() and x2apic_enabled() use rdmsr(msr, low, high),
but only use the low part.
gcc4.6 complains about this:
.../apic.h:144:11: warning: variable 'high' set but not used [-Wunused-but-set-variable]
rdmsr() is just a wrapper around rdmsrl() which splits the 64bit value
into low and high, so using rdmsrl() directly solves this.
[tglx: Changed the variables to u64 as suggested by Cyrill. It's less
confusing and has no code impact as this is 64bit only anyway.
