on ARM (including PXA), you MUST set CFG_MEMTEST_SCRATCH to
a valid RAM address (outside the area to be tested, e.g.
the last 32-bit word of your RAM), otherwise the memtest
will try to write to address 0 (which is flash).

To quote the README:
      Scratch address used by the alternate memory test
      You only need to set this if address zero isn't writeable"
