Should this also be portable to the 8xx[F]ADS platforms?

Please note that there is also extensive POST code for MPC8xx systems, which includes an IMHO excellent memory test.

I am currently debugging UPM/memory problems, and a real memory test would be invaluable :)

It won't help much. Usually memory tests test just the memory _contents_ using read and write accesses, while 99% of all RAM problems happen in burst mode, i. e. while fetching instructions or while doing DMA. I have yet to see a RAM test that catches this reliably.
