For the test I created a "pattern file" which is filled with the unsigned
long 0x0055aaff.  Using the Abatron BDI3000, I can write the pattern file to
the ram and re-read it without problems.  The same applies to u-boot (write
ram via tftp, dump contents).

Does it work with byte, word and long accesses?
