[U-Boot] Hello-World Standalone Crash on Exit

[Darcy Watkins]

Hello,

I test drove the standalone program for hello world and found it causes a crash/reset when you hit the key to exit the program.  The u-boot I am using is actually based on a git d69dba367aed051663d0ee1ece013c8232bfa9f5 snapshot from the u-boot-mpc85xx branch.  It appears like the standalone program attempted to return to NULL for some reason.  I'm running this on a P1022DS (built for the 32bit, not 36bit addressing).
