  imx51 randomly truncates serial input at 31 characters

  Fix Committed
Status in “linux-linaro-mx51” package in Ubuntu:
  Confirmed

Bug description:
  In the process of trying to work on some test automation, I noticed some commands were failing when sent to the serial port on my imx51 board.  Sometimes the whole command would go through, sometimes it would truncate at 31 characters.  I was not able to reproduce this in uboot, or with other boards I've tried so far.  An easy way to reproduce, is to create a long string and cut/paste it on the serial console.  Here's an example of me trying this:
  1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890
