Well, that was the starting point of my questions - don;t you want to
have a single image runnign on all of your systems?  That's exactly
get_ram_size() has been made for...

get_ram_size() is not about configuring, but about verifying /
checking the result of such a configuration.

That's OK - but this is still no reason not to support all these
configurations in a single U-Boot image.   After all, this is exactly
how U-Boot has been designed right from the beginning.
