This master node is an SPI flash controller 'n25q128a13'. Since there is no 'partitions' node declared, one full sized partition named as the device will be created. Cc: Gregory Clement Cc: Thomas Petazzoni Cc: Lior Amsalem Signed-off-by: Ezequiel Garcia Tested-by: Gregory Clement --- This patch depends on: 1. Gregory's patch for Armada XP GP board: arm: mvebu: support for the new Armada XP development board(DB-MV784MP-GP) 2.
