* [U-Boot-Users] Interrupt initialization for ppc440 @ 2005-07-22 22:04 Shawn Jin 2005-07-23 0:05 ` Stefan Roese 0 siblings, 1 reply; 3+ messages in thread From: Shawn Jin @ 2005-07-22 22:04 UTC (permalink / raw) To: u-boot 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?

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