[U-Boot] Rockchip RK3288 boot trouble

[Rick Bronson]

Hi Kever and Simon,

  Thanks very much for the help.  Really appreciate it.

  I'm using this method:

  See below for the output.  I noticed that I only have "Channel b"
and not "Channel a".  On my other board that boots, I have both a and b. I
wonder if one bank of DDR3 went bad on this
board.  What do you think?

  Thanks again.

  Rick
