If you have to ask such a question this is  an  indication  that  you
don't  have  the  qualification  to  port  U-Boot.  When dealing with
software on such a low level as the boot loader you need  a  thorough
understanding  of  the  hardware  and it's internal workings. Without
this you are lost.

No offence meant.

Best regards,

Wolfgang Denk
