Hi,
  Ok the first round of changes are in. These changes separate the
hardware and software interrupt masks allow up to 32 of each type of
interrupt. This was needed as the DC21285 core logic uses a 32 bit
interrupt register thus there was no room to steal bits for the soft
interrupts. With this a serial interrupt priority level and a soft serial
interrupt priority level have also been added which may help serial
performance.
Changes have also been made to the interrupt dispatch code to shave a bit
of time of the dispatch latencies.

Next will be the adding of the DC21285 'Footbridge' core logic support.

Cheers,
				Mark
