Hi All.
When i do a memtest without any args, it crashes after printing the
first line. I know the output may vary depending on the processor and
the memmap.
I just wanted to knoe is this tha appropiate behaviour for mtest.

<The serial console just freezes here, meaning an evident crash>
After reboot, when i do and md for the base address 0x0, i get the
following, which proabbly is the uboot image itself in RAM. So i am
guessing, the memtest tries modifying the U-boot in memory and hence
the crash. i am not sure though Please correct me if i am wrong.
Here's the message log.
