armv7-lpae-x:

lpae = 
https://en.wikipedia.org/wiki/ARM_architecture#Large_Physical_Address_Extension

It was added with the Cortex-A15, The Cortex-A7,A12,A15,A17 all have it..

Devices which don't have it, Cortex-A5,A8,A9 will NOT boot with it enabled..

Right now, this only supports the omap5_uevm, BeagleBoard-X15...

armv7-x:
general image that'll work with most boards...

bone:
tweaked config for the BeagleBone family (am335x), which enable a few
things we can't enable on the general image due to errata on the older
Cortex-A8 used on the BeagleBoard/Beagleboard-xM.. (Which allow us to
get a little more performance out of the am335x)
