How about using get_ram_size() for auto-sizing and testing?
the RAM needs to be properly initialized in low level before being able to test it so its geometry (rom/columns) and timings must be known before being able to detect its size using get_ram_size. I'm not sure it's possible to use a generic geometry/timings there else u-boot may never relocate. How would you do this ?

Please swap to keep sorted:

OK will do.
