I just fixed it by comenting out setting baudrate, then it will leave it as
it was after dBug. Now i get kernel booting up and initial strings
coming out
but kernel crashes after initMMU ( early boot prit enabled ),
I think that i have something wrong in .config.
I did not find goog example gor 5200lite from denx tree so i made
my best quess and it seems not to bee so good.

-- continues hacking ....
