Software modification needeed to use Rev-E1 and Rev-E2 version of LP-AM261 EVM

Note
  You may ignore this page if Ethernet CPSW driver (enet-lld) is not used

Out-of-box networking (CPSW) examples seamlessly support the Rev-A LP-AM261 board version. Modify the following changes in CPSW example Syscfg-GUI to use Rev-E1 and Rev-E2 board

1. Add two EEPROM instances in 'Syscfg‑Gui → TI BOARD DRIVERS → EEPROM'

1.1. If 'Mac Port 1' is used, create an EEPROM instance named `CONFIG_EEPROM_PORT1` with I²C address `0x52`.
1.2. If 'Mac Port 2' is used, create an EEPROM instance named `CONFIG_EEPROM_PORT2` with I²C address `0x53`.

2. Update the 'Syscfg‑Gui → TI BOARD DRIVERS → ETHPHY' instances for add‑on PHY usage

2.1. If 'DP83826-EVM-AM2' add-on PHY is used
2.1.1. Set 'ETHPHY Device' in `CONFIG_ENET_ETHPHY0` to `DP83826` and 'Phy Address' to `3`.
2.1.2. Set 'ETHPHY Device' in `CONFIG_ENET_ETHPHY1` to `DP83826` and 'Phy Address' to `1`.
2.1.3. Map `CONFIG_ENET_ETHPHY0` to 'MacPort 1' and `CONFIG_ENET_ETHPHY1` to 'MacPort 2'.
2.1.4. Configure either 'MII/RMII' interface in 'CPSW pinmux config'.

2.2. If 'DP83TG720-EVM-AM2' PHY
2.2.1. Set 'ETHPHY Device' in `CONFIG_ENET_ETHPHY0` to `DP83TG720` and 'Phy Address' to `8`.
2.2.2. Set 'ETHPHY Device' in `CONFIG_ENET_ETHPHY1` to `DP83TG720` and 'Phy Address' to `12`.
2.2.3. Map `CONFIG_ENET_ETHPHY0` to 'MacPort 1' and `CONFIG_ENET_ETHPHY1` to 'MacPort 2'.
2.2.4. Set 'Link Speed Capability' and 'Link Duplexity Capability' to `ENET_SPEED_1GBIT` and `ENET_DUPLEX_FULL` for both MAC ports in 'MAC Port Config'.
2.2.5. Configure 'RGMII' interface in 'CPSW pinmux config'.
