Interrupt initialization for ppc440
Hi,
IIRC, Interrupt usually doesn't have to be enabled on U-Boot. When looking into ppc440 code cpu/ppc4xx/interrupts.c, I noticed that uic0/1/2 are actually enabled for ppc440 targets. Is there any 440 chips using interrupts on U-Boot?
Thanks,
-Shawn.

Yes. All PPC4xx chips (405 and 440) use interrupts for the ethernet drivers. Try looking for "irq_install_handler" to see, where interrupts are used.
Best regards,

Thanks. I found that too. Just needed more patience.
