I didn't build it but I have the sources from Intel. The addressesare the
following (file elf-lrh-rom.specs):

*link:
-T bsp.ld%s -Ttext 0x00000000 -Tdata 0xc0000000 %(old_link)

That's why I'm forcing to execute PLATFORM_SETUP1 and remapping the memory
there according to what you've just said. But it looks like I'm missing
something then.

The No refers to which question? :-)

Ok. I'll do that.
