[meta-freescale] Booting imx6q Saber SD

[Thomas Senyk]

The problem solved itself.

I've unplugged the board (to do something else) and re-plugged everything to, 
exactly as before, with the same sd card and everything ... to get the full 
kernel log

Now he's booting flawlessly ... it was either a loose cable (where it's hard to 
see which cable could have been loose) or one of those position-of-moon-and-
stars problems ;) ... maybe it was due to playing around with DIP1 and 2...

Anyway: Thanks for the Help!
