[PATCH 1/5] ARM: am335x: phyFLEX-AM335x: Split DT and add MLO DT

Wadim Egorov w.egorov at phytec.de
Wed Feb 4 06:00:49 PST 2015


To support different module variants, this patch splits the phyFLEX DT
in dts and dtsi.

And we are also adding a DT for the MLO, which has all bootable devices
disabled. The bootsource is checked in the board file and only the needed
device is enabled and registered.
