1927b3d020
This is a new mechanism for generating interrupt tables which will
be useful on many architectures. It replaces the old linker-based
mechanism for creating these tables and has a couple advantages:
1) It is now possible to use enums as the IRQ line argument to
IRQ_CONNECT(), which should ease CMSIS integration.
2) The vector table itself is now generated, which lets us place
interrupts directly into the vector table without having to
hard-code them. This is a feature we have long enjoyed on x86
and will enable 'direct' interrupts.
3) More code is common, requiring less arch-specific code to
support.
This patch introduces the common code for this mechanism. Follow-up
patches will enable it on various arches.
