This doesn't work as-is with the software model as accessing some of the
peripherals that aren't modeled will cause an exception. Is it worth
having a device tree file suitable for the models? Or are the models too
configurable for this to be workable?

If CONFIG_ARM_ATAG_DTB_COMPAT is enabled the device tree will end up
with two nodes describing the memory ("memory" and "memory at 80000000" in
this case).

Subject: [PATCH] ARM: vexpress: rename device tree "memory at ..." nodes to
"memory"
If CONFIG_ARM_ATAG_DTB_COMPAT enabled it expects the memory
information to be in a node named "memory". If the memory is
described in a different node, the device tree will end up with two
nodes describing the memory.
