Ebony bootloader

Does the Ebony board port implement a bootloader? What
does the head_440.S file do in a nutshell?

If our custom board has peripheral devices hanging off
the EBC0, how should I initilize them and where in the
ebony port code? I browsed the source a little bit and
see the ebony.c source. I believe this is where you
add peripheral devices to the kernel. Am I right?

What is that ioremap64() anyway? Is this a kernel call
or a called supported by the firmware?

Thanks,
