The ethernet controller used on kirkwood looses its MAC address
register contents when the corresponding clock is gated. As soon as
mv643xx_eth is built as module, the clock gets gated and when loading
the module, the MAC address is gone.
Proper DT support for the mv643xx_eth driver is expected soon, so we add
a workaround to always enable ge0/ge1 clocks on kirkwood. This workaround
is also already used on non-DT kirkwood kernels.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

make sense to split them up across the cross-platform topic branches. So
here they are (for the second release in a row) in a branch on their own.

Ok, I did convert the i2c definition to use the devicetree.
The adt7476 device itself is not at reach of device tree,
AFAIK and requires more work at there?
Thanks for your valuable comments. Following is a new patch that
should address the problems and mistakes you pointed and also
some of the pointed by Jason Cooper. The nand and i2c are now
defined at DT and I also removed the pointless defines and
ARM_APPENDED_DTB. It is based against the Linus' official

kirkwood_rtc_init(). This maintains compatibility with non-fdt
configurations because they still call kirkwood_init() in common.c.
As drivers are converted, we will reinstate the 'static' qualifier in
common.c.

This uart is the primary console for the dreamplug. Removed
kirkwood_uart0_init() call from board-dt.c.

Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.
Then, switched to SPI based NOR flash.
After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support. First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.
Driver porting will start with the uart (see next patch), and progress
from there. Possibly, spi/flash/partitions will be next.
When done, board-dt.c will no longer be dreamplug specific, and dt's can
be made for the other kirkwood boards.
