Well, you would see the unexpected  size  printed  with  the  startup
messages.  That's something you should always look for: memory sizes,
clock frequencies, etc.

Wrong, there is.

First, there is common/memsize.c which includes a simple but pretty
efficient (and fast) memory test.

Then there is common/cmd_mem.c with it's two different implementations
of do_mem_mtest(), depending if CFG_ALT_MEMTEST is set or not.

And finally, there is post/memory.c which is where you copied the code
from. Why didn't you use post/memory.c ?
