For the "test" part, it is probably much easier to add a customized memory test (or fix just the existing memory test such that it can be built for a 64 bit mode) and use this, then trying to run all of U-Boot in 64 bit mode.

There already is PowerPC memory test code in U-Boot that supports more than 2GB. It uses sliding TLB windows. If it doesn't already support 12GB, then it should be easy to add that support.
