I am seeing a hang on my ARM boards that are using NAND flash for the
env.  The hang seems to be env contents dependent.  I'm still
investigating, but it could be related to the issue you're seeing.
For me it hangs (sometimes, depending on env) after mmc init and
before console init traces anything.
