This patch set targets to add support for CONFIG_DM_ETH for the NXP LS2080AQDS board.
The main focus is on changing the DTS based on the SERDES protocol used. In order to accomplish this, the MULTI_DTB_FIT feature is employed and the appropriate DTS is chosed on boot from a list of predefined files.
Any unnecessary configurations made for the DPAA2 ethernet devices in the board files are compiled out when CONFIG_DM_ETH is enabled. This is because any information necessary is available in its associated DTS node.
This patch set depends on another series that adds support for DM_ETH in the ldpaa_eth driver and the RDB boards: https://patchwork.ozlabs.org/project/uboot/list/?series=165158&state=*
For the moment, when CONFIG_DM_ETH is enabled DPAA2 networking is supported only for the SERDES block #1 protocol 42 (0x2a).
