Initially IVT for ARCv2 was simply copypasted from ARCompact with some selected fixes so basic stuff works. Now we update it with more ARCv2 specific vectors like * Software Interrupt * Division by zero * Data cache consistency error * Misaligned access Also normal interrupts are now implemented properly and extened to all possible 240 items.
