This is the question I raised on this list a week or two back ("omap3 startup
memory map", 6 Sep). I had a very helpful conversation with Richard
Woodruff this afternoon. So the good news is that I have a much better
idea of what the hardware does; the bad news is that qemu isn't really
in a position to model it :-) [the omap3 apparently hides its boot ROM
for most purposes using a combination of trustzone and some special
hardware so that the effect is that code can't see it but it still gets to
control what happens on exceptions. I'll have a think and look at the
code to see if there's anything we can sensibly do but it might well be
that the "don't let the GPMC map anything at address zero" bodge is
the most pragmatic thing for now.]
