Umm... This is not how it should be done.

U-Boot should *never* assume  static  flash  bank  sizes.  The  whole
design  is  based  on  the idea to automatically determine the actual
size of flash and RAM that  is  fit  on  a  specific  board,  and  to
auto-adjust for this.

There are many vendors out there who manufacture boards in  different
memory  configurations.  For  these it is essential that they can use
only one U-Boot image on all boards, no matter what the exact  memory
configuration of this board is.

I am aware that there are ports out there which violate this design
principle, but if we touch this area, thenplease only to make more
boards conformant, not to make things worse.

Thanks.

Best regards,

Wolfgang Denk
