Assume you have a board that comes with either 32 or 64 MB of RAM. At
the moment, U-Boot always relocates to the end of the RAM, i. e. you
have some 31+ resp. 63+ MB free contiguous RAM to load an OS and
application images etc.

If you use a static link address you would always relocate U-Boot
below the 32 MB limit.

Now explain to a customer with a 64 MB RAM configuration why he
cannot load a ramdisk image of 33 MB...

Best regards,
