Greetings, I am trying to write a BSP for an 8245 based device. One thing which really gets me puzzled is the 'ISU' facility in arch/powerpc/sysdev/mpic.c, there is also a notion of ISU-less platforms, etc. I looked through the chip's programmer's reference, even read the original AMD/Cypress OpenPIC specification - not a clue.
What is it, at the very least - what does ISU stand for? I would really appreciate any hints, thank you in advance, /vb _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
