I suggested another solution: http://patchwork.ozlabs.org/patch/123074/
This has the disadvantage, as discussed in the thread, that the address passed to mmap is not guaranteed to be returned.
I don't see why this would be needed.
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?
