[U-Boot] [PATCH 1/3] arm: mvebu: Add armada-xp-maxbcm.dts for maxbcm board
Stefan Roese

Fri Nov 27 11:29:07 CET 2015
This is needed for the upcoming ethernet DM conversion of the maxbcm
board. The configuration of the PHY is then extracted from the DT
instead of using the defines from the config header.
