Changes in V2: ============= Address review comments: - Remove support for detecting multiple device trees using different DTB - Remove board specific API from K3 generic file (arch/arm/mach-k3/j721s2_init.c) and moved to board specific file (board/ti/j721s2/evm.c). * arch: mach-k3: Update board specific API name to K3 generic API name * board: ti: j721s2: Add board_init and support for selecting DT based on EEPROM - Move board_is_xxx within CONFIG_TI_I2C_BOARD_DETECT block to maintain the "mini" U-Boot concept for this SoC.
