The latter ;-)

Haven't yet thought about this. But one question is more interesting for
me at the moment -- what early hardware initialization is needed for the
setup (if at all)? Is the setup documented somewhere? Is there a
standard (for the low-level init, mind you!) or is this completely
vendor-dependent?

Does the init have to work before the RAM is initialized, or can it be
done after RAM works?

Do we have public datasheets for this stuff? Any datasheets at all?


Uwe.
