[PATCH 0/4] board: freescale: T2080RDB: rev D support and

[Camelia Groza <camelia.groza@oss.nxp.com>]

From: Camelia Groza <camelia.groza@nxp.com>

The T2080RDB boards revision D and up have updated Aquantia PHYs on the
two 10Gbps copper ports connected to MAC1 and MAC2 (from AQ1202 to
AQR113C). The second PHY connected to MAC2 is located at a different
address on the MDIO bus compared to revision C boards. Device tree
fixups are required for both Linux and u-boot to set the correct PHY
address for the new board revisions.

While we are here, the first patch cleans up the T2080RDB board files
and removes legacy non-DM_ETH code paths. DM_ETH and DM_PCI are enabled,
so board_eth_init() isn't required anymore.

The second patch in the series implements a callback that detects the
board revision based on the CPLD registers.

The third patch adds the PHY address fix-up for Linux's device tree.

The last patch corrects u-boot's device tree under DM based on a newly
introduced CONFIG_T2080RDB_REV_D build option. We are unable to use the
board_fix_fdt callback to update the device tree before relocation because
the dts is stored in flash at that point and isn't writable. Instead,
this config option is used until a more robust solution is implemented.
Defconfig targets with the config option enabled by default are added for
convenience.

Changes in v2:
- remove legacy non-DM_ETH code paths at Tom's recommendation in 1/4
- patch title and description rewordings in 2/4 and 3/4
- drop "board: freescale: t208xrdb: add rev D support for the non-DM_ETH
  mode"
- move the AQR113C_PHY_ADDR define from the dropped patch to 3/4
