configs/beagley_ai_defconfig: new defconfig

Browse Source 
Adds support for BeagleY-AI board by introducing the
beagley_ai_defconfig file and related support files.

The BeagleY-AI uses the TI J722S SoC, also known as AM67A, also
known as TDA4VEN or TDA4AEN.

Retrieve BSP settings from meta-ti (may be useful for other TI boards):

- Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_TARGET_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/j722s.inc:TFA_BOARD = "lite"

- Set BR2_TARGET_UBOOT_NEEDS_ATF_BL31 to provide BL31 variable pointing
  to ATF bl31.bin to the U-Boot build process [1].

- Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE to OP-TEE as BL32
  secure payload. meta-ti set "SPD=opteed" to build ATF [2].

- Set BR2_TARGET_OPTEE_OS_PLATFORM to "k3-am62x".
  meta-ti uses the OPTEEMACHINE to set optee-os platform [3].
  meta-ti]$ git grep OPTEEMACHINE
  meta-ti-bsp/conf/machine/include/j722s.inc:OPTEEMACHINE = "k3-am62x"

- Use am67a_beagley_ai_a53 and am67a_beagley_ai_r5 u-boot
  defconfigs introduced in u-boot v2025.07 [4]

- u-boot distroboot (bootflow) detect extlinux.conf file from the first
  SDcard partition, so we have to install the kernel and its dtb file.
  Use devicetreedir instead of devicetree in extlinux.conf file to
  avoid hardcoding the devicetree file name. TI boards are able to
  retrieve dtb file name from an EEPROM (see TI_I2C_BOARD_DETECT in
  uboot).

- Use 6.15.6 stable release instead of the latest 6.12 LTS since the
  k3-j722s support was only introduced in 6.11 kernels.

- Provide a hash file for all custom package version
  (arm-trusted-firmware, linux, ti-k3-r5-loader, uboot) to enable
  BR2_DOWNLOAD_FORCE_CHECK_HASHES.

BeagleBoard.org BeagleY-AI Development Board
Description
===========
This configuration will build a basic image for the BeagleBoard.org
BeagleY-AI. For more details about the board, visit:
https://www.beagleboard.org/boards/beagley-ai
How to Build
============
Select the default configuration for the target:
$ make beagley_ai_defconfig
Optional: modify the configuration:
$ make menuconfig
Build:
$ make
To copy the resulting output image file to an SD card use dd:
$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
How to Run
==========
Insert the SD card into the BeagleY-AI board, and power it up
through the USB Type-C connector. The system should come up.
You can use a USB to serial adapter to connect to the connector
labeled UART0 (J13) to communicate with the board.
