attempt to access it from U-Boot leads to an immediate crash.
So let's make the same memory reservation as the vendor device tree.

I'm wondering if this reservation is only necessary and at this address
for the mcbin or also for other (or even all) Armada 7k/8k boards? If
global, then it would be better to move this reservation to a common
dtsi file instead.
Thanks,
Stefan
