This is a prelude to intr-ng support for MIPS boards that need it - notably the CI20 port from kan@ that's upcoming, but also work that Stanislav is doing for the Mediatek platforms. This is the initial platform dependent bits in include/intr.h, some #defines for the nexus code for the intrng initialisation/runtime bits, some changed naming (which I'll fix later to be the same, much like what I did for ARM intr-ng) in exception.S, and the first cut at a PIC. Stanislav and I refactored out the common code for intrng support, so the mips intrng definitions are quite small (sys/mips/include/intr.h.) This is all work done by kan@, which stanislav has been cherry picking into common code for his mediatek chipset work. Tested: * Carambola2 - no regressions (not intr-ng though!)
