Hi All,
This series of patch add initial support for AM68 starter kit.
Design files can be referrred from https://www.ti.com/lit/zip/SPRR463

Refer below link to J721S2/AM68 Technical Reference Manual for further details:

Changes in V3:
=============
Address review comments:
- Rework on DTB selection API clarity about mini-U-Boot vs EVM and family support as suggested.
  * board: ti: j721s2: Add board_init and support for selecting DT based
    on EEPROM

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.
