One problem is if Mon8xx initializes the hardware before calling U-Boot.
U-Boot may not work if some hardware is already initialized before U-Boot
starts. I have this problem with my BDI-2000 hardware debugger. If I let the
BDI initialize flash (so that I can write to it), U-Boot will hang when it starts.
