Yeah, the closest to a "standard" we have for nios2 is that I asked the Codesourcery folks to document it in the libgloss sources and put the URL to it in a comment at the top of nios2-semi.c, given that there's no official spec and the original and main guest-side user is libgloss. m68k is in a similar position only without the URL in our source file :-) -- PMM
