Hi Matt,

We are in a process of developing a SoC around cortex a9 quad core
versatile express. For that we made changes in the U-Boot. Is there any
way (like any simulator/emulator which supports this board) to validate
the changes before getting the arm board itself.

Any kind of help is highly appreciated.
