I have a couple of questions about interrupt initialization. I compared the two platform-specific files for the 405EP and 405GPr processors. The first one (evb405ep.c) does not initialize the ibm4xxPIC_InitSenses to setup all the IRQ lines while the second one (sycamore.c) does. Both of them define the function ppc405_map_irq to setup IRQ lines associated with PCI slots. My questions are: 1) Why does not evb405ep.c use ibm4xxPIC_InitSenses to initializes IRQs (polarity, level/edge etc)? 2) In my understanding the function ppc405_map_irq is used to inform PCI subsystem about PCI slots IRQ routing. Is it correct?
