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.
Should we add support for MMX and SSE2 also?
I have also found another issue which I run out of heap space while the
PCI resource structures are being malloc'ed. Doubling the heap size
solves the issue.
Here are the patches I am currently using:
