The SPARC high end platforms starcat and starfire include a lot of code which we will never ever see run with illumos. These platforms are better known as the E10000 and SF20K (and also 15K and 25K). We don't have everything necessary to support these platforms, and its extraordinarily unlikely that anyone will ever want to run illumos on them.
Elimination of the code for them would save a lot of SPARC-specific complexity.

Bits to remove include:
