The dtb support in u-boot has been enabled but that has been done in
my copy of u-boot. The linaro u-boot does not include support for
s5pv310 yet.

Done and tested.

Will do this as next task.

The watchdog timer driver was modified to be probed from device tree
and it is working fine (will work for both dt and non-dt versions).
Other work items that will be taken up next are

- Retrieve the default UART register values from the device tree
during UART initialization.
- Add SDHCI_OF support for SDHCI s3c driver, required to support DT
enabled sdhci driver for s5pv310
- Initialize timer and GIC from dt.
- Support dt for gpio, i2c, spi, uart, srom controller.

Thanks,
Thomas.
