On a semi-related note: the current obstacle to moving more devices over to using FDT on BERI is that our FDT implementation appears to require a PIC to be configured. We're not actually using a PIC on BERI currently. It works fine attached to nexus, as the implied fallback for not having a PIC is to simply use the suitably numbered interrupt wires direct into the MIPS. However, trying the same setup described using FDT leads to an interrupt-related warning at boot, and no interrupt being provided to the driver. I suspect I need to provide a PIC-alike software component as a fall-back for the non-PIC case. From a brief e-mail exchange with JC, it sounds like the XLP FDT setup is actually not using interrupts either, currently.
