As an example look at initdram() in board/Marvell/db64460/sdram_init.c where the platform uses Block Address Translations (BATs) to map RAM but exhausts these pretty scarce ressources and limits itself to mapping only the first 256MB (a usual limit for a BAT).
So it is possible to overlay the function memory_post_test() by a board specific routine, which may cover almost all RAM?
Everything is possible - this is software, so anything can be done. You can even make pigs fly. But not everything does make sense.
BTW, is it possible to overlay _all_ POST routines by board specific routines?
It could be done, but I consider it a very, very bad idea.

And what if the tests wouldn't meet certain requirements of the developer or customer or if it had to be adapted to CPU- or board-specific conditions? I suppose, you wouldn't like much "#ifdef <CPU>"s or "#ifdef <board>"s in common code. Could you please make a proposal to solve this and to get such code into the official U-Boot tree?
Kind regards Jens
