Well after turning off CONFIG_FIT in u-boot, I sat staring at
'Starting kernel ...' and then a root login popped up. So it does not
seem to like 'console=ttyS2,115200n8' very much.. and for that matter
ttyO2 doesn't work either... hrrm.

Now to figure out if I can make LCD/omapfb work again...

(FYI, it seems 3.14-3.18 mainline series kernels would work with the
am3517-evm with 'nohlt' on the command line without a device tree)
