[PATCH v1 01/23] board: nxp: add Nodebox v3 CPU Module (LX2160A) base port

Vincent Jardin <[email protected]>
Newsgroups org.u-boot-project.lists.u-boot
Message-ID <[email protected]> 
Introduce TARGET_NBXV3 for the Free Mobile Nodebox v3 CPU Module, an
LX2160A based platform.

eth_nbxv3.c renames the DPAA2 Ethernet devices from a "u-boot,nickname"
DT property (EVT_DM_PRE_PROBE spy) to something more user explicit.

Currently the CONFIG_ID_EEPROM is not set since the NXP format is not
used on this board.
