2c05915b24 add nol2x0 cmdline to disable l2x0 cache
L2 cache via L2X0 cache controller available on some ARM boards can
provide a performance boost in some situations but decrease performance
in others.  This adds a kernel cmdline to disable L2X0 for cns3xxx based
boards.

822ee5053e cns3xxx: fix dwc_otg driver compat with udc-core
function.  This removes those from the dwc_otg driver and removes the patch
that comments out the linkage of udc-core so that the dwc_otg driver can
co-exist happily with other USB Device Controllers.

3c12bad276 move PCIe init to subsys init call
ARM Linux PCI/PCIe hardware intialization needs to occur before device_init
as it does not support hotplug.  I have modeled the cns3xxx PCIe init after
other ARM platforms.  Registering it early resolves resource issues occuring
during bus enumeration that occur when a device driver is linked static in
the kernel.

Instead of passing in a bitmask to enable the 2 available ports, link detect
is used to enable ports that have a valid link.

879b7a7a9b cns3xxx: update FIQ header file and disable RWFO
Update header file appropriately and disable read for ownership

Note that the FIQ support implements a workaround that provides a performance
boost over the traditional upstream workaround which ensures cache lines
are exclusive on driver CPU using 'read for ownership'.

6bb7409e5a cns3xxx: Fix laguna arm11mpcore watchdog
The ARM11MPCore Timer/Watchdog registers start at offset 0x600 which is where
all mpcore-wdt boards point the driver base too.  I believe this is wrong
because 0x600 is aliased to the timer/watchdog of the 'current CPU' where
0x700 is CPU0's timer/watchdog, and 0x800 is CPU1's timer/watchdog.  Thus
if your timer/watchdog application is switching between CPU's it can end up
writing to the wrong CPU's registers which results in random board resets
from watchdog timeouts etc.

This patch forces the timer/watchdog driver to use CPU0's registers always.
Its my opinion that other mpcore-wdt boards should be doing the same thing.
