Because you will have the same address for "physical memory" in all
instances of sandbox u-boot. This could simplify test scripts a bit.
Imagine testing tftp downloads to memory where DRAM bank-> start is
different for every program run. This was a PITA for me while testing
the tap ethernet simulation for sandbox. And that is why I came up with
the patch.

Or is there something like $(ramstart) in u-boot?
