The problem with Truxton booting in trunk seems to have appeared in the migration to the new Makefile system.
If I drop a CONFIG_SSE=y into the .config file using a trunk build I can boot!
However, I don't really see how this flag gets set. Doing a 'grep -RH CONFIG_SSE' points to the two makefile includes that add the enable_sse code, but no references to setting the flag.
I added it in 5505. I think we should put an #error in the file that uses these instructions if CONFIG_SSE isn't set.
Thanks, Myles
