This patch sets up the NAND registers to use 8-bit NAND flash. This is from
the MX27ADS code, and was removed during the porting effort.

The SD interface has configurable pullup resistors that need to be set. It
also relies on a couple of functions to determine the state of the chip select
and to pass the chip select interrupt to the platform data.

The GPIO interrupts on the MXC platforms can be masked on either the pin or
port level, but no method existed to mask them on the port level. This patch
adds that support and unmasks the ports on the MX27 when an IRQ is unmasked.

The PMIC uses a different GPIO pin on the Litekit than it did on the ADS.
This changes the pin to the proper value.

One of the USB registers were incorrectly written, and the PMIC header file

There was additional MMC code that is no longer used in the MX27 Lite file, and

The Lite kit only uses the first UART. The rest have been scavenged for pins.
This disables all UARTS but the first so that there are no more pin conflicts.

The GPIO pins for the MX27 are read differently than those on the MX31. Rather
than reading the Data Register (DR), you must read the Sample Status Register
(SSR).

The MX27 crm_regs.h file was a complete mess, obviously hastily ported from
the MX31 version, which was also a mess. I cleaned it up quite a bit,
although more work still needs to be done such as fixing the naming
conventions.
This is build tested on the MX27 Lite Kit. It may break MX27 builds.

The Dynamic Processor Temperature Control Module is significantly different on
the MX27 as compared to the MX31. It seems that some MX31 code slipped into
the MX27 devices file, but essentially did nothing except try to register a
device that didn't have a driver. I removed this code.
I also fixed an issue with the Kconfig where you could select the DPTC module
without the power management chip enabled, which causes a compilation error.

There were a lot of carryovers from the MX27 ADS code that were either
useless or just plain wrong. This commit gets rid of these issues.

Enabling the SD interface on the MX27 chip will enable all of the interfaces.
Since we only use one of them, we should be able to flip them on and off
individually.
Ultimately, we'd like to do this is the board-specific file, but that will
require additional work.

The USBOTG interface uses two GPIO pins for its PWR_EN and OC signals. These
pins are associated with the OTG interface and the PWR_EN is cleared since
the power enable signal for the power controller is low-true.

The USB Host 2 on the MX27 Litekit uses the USB_POWER and USB_OC_B pins for
power and overcurrent detect, respectively. In order to make them function
properly, we need to assign those pins to the Host 2 driver and change the
H2PM field of the USB_CTRL register on the i.MX27.

USB Host 2 and SPI 1 only conflict with one pin. If the SPI bus is not using
the slave select 2 (SS2) pin (which the Atlas chip does not), then you can use
both the SPI 1 and USB Host 2 interfaces simultaneously. This patch disables
the MSB of the slave select if Host 2 is enabled. This will limit SPI1 to
only 4 slaves instead of 8.

Because the data field was never filled and a binary sysctl handler was
never written this sysctl has never been usable through the sys_sysctl
interface. So just remove the binary sysctl number. Making the kernel
sanity checks happy.

When we set the MFGPT timer tick, there is a chance that we'll
immediately assert an event. If for some reason the IRQ routing
for this clock has been setup for some other purpose, then we
could end up firing an interrupt into the SMM handler or worse.
This rearranges the timer tick init function to initalize the handler
before we set up the MFGPT clock to make sure that even if we get
an event, it will go to the handler.
Furthermore, in the handler we need to make sure that we clear the
event, even if the timer isn't running.

This reverts commit d4d25deca49ec2527a634557bf5a6cf449f85deb.
It tried to fix long standing bugzilla entries, but the solution was
reported to break other systems. The reporter of
http://bugzilla.kernel.org/show_bug.cgi?id=9791
tracked it down to this commit and confirmed that reverting the patch
restores the correct behaviour. It's too late in the release cycle to
find a better solution than reverting the commit to avoid regressions.

The JMPRS register on Malta boards keeps a 32-bit CPU-endian
value. The readw() function assumes that the value it reads is a
little-endian 16-bit number. Therefore, using readw() to obtain
the value of the JMPRS register is a mistake. This error leads
to incorrect reading of the PCI clock frequency on big-endian
during board start-up.
Change readw() to __raw_readl().
This was tested by injecting a call to printk() and verifying
that the value of the jmpr variable was consistent with current
setting of the JP4 "PCI CLK" jumper.
