e63eecd71b Deactivate the watchdog timer during attach. 
Recent u-boot starts up the watchdog timer, and we don't detect this so
e.g. my DE0 nanosoc reboots after about 20 seconds. Applying a reset to
the watchdog circuit is the only way to stop it according to the
documentation.

40b6d94127 Provide an FDTBASE option which allows kernels to access FDT parsing 
functions without requiring full blown FDTisation.

This will be used by ODROID-C1 in move to generic start code.

51b425ef08 Pass clock provider's phandle to fdtbus_clock_controller_func.decode() 
and update callers.

This allows to accomodate clock managers whose clocks are identified
directly by a clock instead of a pair (clock provider, index).

8d4a1027a6 When attaching child devices, consider the best match for all passes
