[U-Boot] testing u-boot on virtual environment

Thanks!

Tried to do some memory display commands but got instant segmentation
fault, and tried to run it as root - but then some bad things
happened, so now I know no one should run it as root.

I wanted to tryout a memory test algorithm I developed, but it seem
u-boot runs with no ram access. If I could findout the ram address
where it is located, I think then the 8MB it says it has wouldn't give
me segmentation fault...
