Btw, do you consider to remove this also?
I just sent a patch for that. Feel free to squash both.

There is now only on defconfig for the at91rm9200 and at91sam9. Add ethernet
support for the rm9200.

Restarting on an at91rm9200 is handled by using the system timer. Move that

The register range from the system timer is also used by the watchdog driver.
Use a regmap to handle concurrent accesses.

This patch sets cleans up the system timer driver.
The main goal is to get rid of the mach/ headers dependency. At the same time,
it introduces proper probing and locking (using a regmap) for the watchdog
driver.

Hans-Christian,
If you want, I guess that one could go through the at91 tree. Unless you have
more material and you want to do
more than once.
