Question about Fiasco.OC support for SPARC

Hi Adam,
  I am grateful for the fast reply!
  I found that the snapshot-2014092821 had already included SPARC-leon support as experimental choice, if I configure "INCLUDE-SPARC=y" to Fiasco kernel, the kernel image can been just built out. But in the snapshot-2015123115, the SPARC experimental choice was been get rid of from Kconfig of Fiasco kernel.
  I guess the development of SPARC support for Fiasco.OC may have reached a high level, but not finished yet by some reasons. So there maybe has a been-done list and a to-do list to recode the progress of the developement like: "MMU is OK","Interrupt/Exception is to do" ... .
  I need to evaluate workload to complete the rest part for running Fiasco.OC on SPARC-leon3. Would you give me some suggestions? Or is there somebody else knows this in more detail?

What's in the snapshot is basically all what's there currently.

Hard to simply enumerate, I'd guess most of the architecture-specific parts.

Hmm, doesn't Gaisler have one?
