A port? of what? CHRP?

OK, so someone at some point will need to write/port the bits of chrp/OF
required by OpenSolaris, if they want to support non-chrp/OF hardware (as
in my case with a barebones embedded board running U-Boot).
It seems to me in this case that grub2 would just be extra work - might as
well just add the required bits to U-Boot.
The real question is, what does OpenSolaris require? I haven't actually
gone and looked at the source (yet), but is it (or will it be) clear? Maybe
it is even documented somewhere?
I don't want to write a complete OF implementation for U-Boot - just enough
to boot OpenSolaris, but maybe OpenSolaris uses so much of OF that you pretty
much have to have a complete OF implementation. Does anyone have a feel for
how much of OF is required by Solaris, and whether the U-Boot idea is
feasible? (keep in mind U-Boot is really lean - used to fit in 64Kb)
Cheers!
