Intel Edison Round #2

Jeff and I have hacked on the Edison and have it starting to
boot with printk() and bsp_reset() working. I added a bunch of
printk's to trace the progress. It is the end of the day and we are
stuck at the create of the first Classic API task in hello world failing
to allocate the FP area.

I am assuming some memory layout issue but I just don't
see it. This board has 1GB RAM per Intel and U-Boot.
It loads our normal pc386 ELF at the right address and runs.

I am throwing this out to the community to see if anyone
has an idea on what to poke at tomorrow. We are tired at
the end of the day.
