With -Werror enabled during the build, the warp.c file fails to build
due to the temp_isr function not containing a return statement. This
fixes the build error and documents that the function never returns.

The GPIO LEDS driver now has a default state of "keep". Update the Warp DTS
and platform file to take advantage of this new state. This removes the
hardcoding of the two LEDs on the Warp.

A change to the i2c subsystem breaks the warp platform code. The patch
is cleaner anyway, the old way was a bit crufty.
For those with keen eyes, the gratuitous change in the string from
PIKA to Warp is just so the logs look a bit nicer. The following two
lines tend to be printed one after another.
Warp POST OK
Warp DTM thread running.
Yeah, this will be the third patch to warp.c submitted in this
release....
Cheers,
Sean
The i2c_client struct changed, breaking the code that looked for the ad7414
chip. Use the new of_find_i2c_device_by_node function added in 2.6.29.

If no device is passed to __dma_alloc_coherent, it defaults to using ISA_DMA_THRESHOLD
for the mask. This patch provides a reasonable default rather than 0.

Now that leds-gpio is a proper OF platform driver, the Warp can use
the leds-gpio driver rather than the old out-of-kernel driver.
One side-effect is the leds-gpio driver always turns the leds off
while the old driver left them alone. So we have to set them back to
the correct settings.

This patch removes the i2c code which is now obsolete due to the new
ibm iic driver walking the device tree for child nodes.
There are two other small cleanups that came indirectly from the ad7414
code review. Make sure Tlow is correct and handle the case where
i2c_smbus_read_word_data fails.

* Switched from 64M NOR/64M NAND to 4M NOR/256M NAND.
* Full DTM support including critical temperature.
* Added POST information.
* Removed LED function, moved to new LED driver.
* Moved ad7414 to new style I2C initialization.

This patch creates a common system reset routine for all 40x and 44x
systems. Previously only a 44x routine existed. But since this system
reset via the debug control register is common for 40x and 44x let's
share this code for all those platforms in ppc4xx_soc.c.
This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms.
Tested on Kilauea (405EX) and Canyonlands (440EX).

While merging, I found a small bug that I forgot to send. I add an
offset to a value twice.
