thsi depends on the architecture. For  some  architectures  like  ARM
this  is  currently  defined by the TEXT_BASE setting in your board's
config.mk file (which we consider a bug that is to be  fixed),  while
for  other  architectures like PowerPC it gets auto-computed to be at
the end of available RAM, no matter how big that actually is (this is
considered correct behaviour).

Best regards,

Wolfgang Denk
