board: ti: j721e: Use EEPROM-based board detection The TI J721E EVM system on module (SOM), the common processor board, and the associated daughtercards have on-board I2C-based EEPROMs containing board config data. Use the board detection infrastructure to do the following: 1) Parse the J721E SOM EEPROM and populate items like board name, board HW and SW revision as well as board serial number into the TI common EEPROM data structure residing in SRAM scratch space 2) Check for presence of daughter card(s) by probing associated I2C addresses used for on-board EEPROMs containing daughter card-specific data. If such a card is found, parse the EEPROM data such as for additional Ethernet MAC addresses and populate those into U-Boot accordingly 3) Dynamically apply daughter card DTB overlays to the U-Boot (proper) DTB during SPL execution 4) Dynamically create an U-Boot ENV variable called name_overlays during U-Boot execution containing a list of daugherboard-specific DTB overlays based on daughercards found to be used during Kernel boot. This patch adds support for the J721E system on module boards containing the actual SoC ("J721EX-PM2-SOM", accessed via CONFIG_EEPROM_CHIP_ADDRESS), the common processor board ("J7X-BASE-CPB"), the Quad-Port Ethernet Expansion Board ("J7X-VSC8514-ETH"), the infotainment board ("J7X-INFOTAN-EXP") as well as for the gateway/Ethernet switch/industrial expansion board ("J7X-GESI-EXP").
