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. =46rom a brief e-mail exchange with = JC, it sounds like the XLP FDT setup is actually not using interrupts = either, currently.
