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.
The first patch in the series implements a callback that detects the board revision based on the CPLD registers.
The second patch updates the PHY addresses in u-boot for the legacy, non-DM, driver implementation.
The third patch adds a fixup for Linux's device tree that is called from both DM and non-DM code paths.
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, the config option is used until a more robust solution is implemented. Defconfig targets with the config option enabled by default are added for convenience.
