[meta-freescale] kernel hangs u-boot 2016.03->07

[Renato Caldas]

Hi Markus,

Have you tried enabling CONFIG_DEBUG_LL and CONFIG_EARLY_PRINTK and
using "earlyprintk"?

I'm myself fighting a problem with the same symptom (no output past
the "Starting kernel"), and it helped to know what was going on.

Cheers,
  Renato
