Adds support for BeagleBone AI-64 board by introducing the beagleboneai64_defconfig file and related support files. The BeagleBone AI-64 uses the TI J721E SoC, also known as DRA829, also known as TDA4VM. Retrieve BSP settings from meta-ti (may be useful for other TI boards): - This defconfig requires u-boot binman support added in u-boot since 2023.10. See FOSDEM 2024 talk by TI folks about Binman and how it simplify the overall boot-loader build flow [1]. - Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_TARGET_BOARD = "generic" meta-ti]$ git grep TFA_BOARD meta-ti-bsp/conf/machine/beagleplay.conf:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/am62axx.inc:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/am62pxx.inc:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/am62xx.inc:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/am64xx.inc:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/am65xx.inc:TFA_BOARD = "generic" meta-ti-bsp/conf/machine/include/j7200.inc:TFA_BOARD = "generic" meta-ti-bsp/conf/machine/include/j721e.inc:TFA_BOARD = "generic" meta-ti-bsp/conf/machine/include/j721s2.inc:TFA_BOARD = "generic" meta-ti-bsp/conf/machine/include/j722s.inc:TFA_BOARD = "lite" meta-ti-bsp/conf/machine/include/j784s4.inc:TFA_BOARD = "j784s4" - Set BR2_TARGET_UBOOT_NEEDS_ATF_BL31 to provide BL31 variable pointing to ATF bl31.bin to the U-Boot build process [2]. - Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE to OP-TEE as BL32 secure payload. meta-ti set "SPD=opteed" to build ATF [3]. - Set BR2_TARGET_OPTEE_OS_PLATFORM to "k3-j721e". meta-ti uses the OPTEEMACHINE to set optee-os platform [4]. meta-ti]$ git grep OPTEEMACHINE meta-ti-bsp/conf/machine/am437x-hs-evm.conf:OPTEEMACHINE = "ti-am43xx" meta-ti-bsp/conf/machine/am57xx-hs-evm.conf:OPTEEMACHINE = "ti-am57xx" meta-ti-bsp/conf/machine/beagleplay.conf:OPTEEMACHINE = "k3-am62x" meta-ti-bsp/conf/machine/dra7xx-hs-evm.conf:OPTEEMACHINE = "ti-dra7xx" meta-ti-bsp/conf/machine/include/am62axx.inc:OPTEEMACHINE = "k3-am62x" meta-ti-bsp/conf/machine/include/am62pxx.inc:OPTEEMACHINE = "k3-am62x" meta-ti-bsp/conf/machine/include/am62xx.inc:OPTEEMACHINE = "k3-am62x" meta-ti-bsp/conf/machine/include/am64xx.inc:OPTEEMACHINE = "k3-am64x" meta-ti-bsp/conf/machine/include/am65xx.inc:OPTEEMACHINE = "k3-am65x" meta-ti-bsp/conf/machine/include/j7200.inc:OPTEEMACHINE = "k3-j721e" meta-ti-bsp/conf/machine/include/j721e.inc:OPTEEMACHINE = "k3-j721e" meta-ti-bsp/conf/machine/include/j721s2.inc:OPTEEMACHINE = "k3-j784s4" meta-ti-bsp/conf/machine/include/j722s.inc:OPTEEMACHINE = "k3-am62x" meta-ti-bsp/conf/machine/include/j784s4.inc:OPTEEMACHINE = "k3-j784s4" - Use j721e_beagleboneai64_a72 and j721e_beagleboneai64_r5 u-boot defconfigs introduced in u-boot v2024.04. - u-boot distroboot (bootflow) detect extlinux.conf file from the first SDcard partition, se 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). - 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
