I've got some of this.  It could use nested interrupt upgrade (non-nested is
there already) and perhaps a more complete makefile.

It's part of the newlib support routines
http://www.aeolusdevelopment.com/Articles/download.html but I don't think any
of the basics depends on newlib.  Also includes some basic set up
routines like
PLL, MAM, VPB and VIC initialization and a wait function.

Documentation is a work in precess as always but it is there and it's
reasonably
commented.
