maybe you could shed some light onto the AM62x situation. My conclusion
is that since your initial buildroot BSP U-Boot has been switched
to standard boot (CONFIG_BOOTSTD), refer to (U-Boot repo):

commit 355c0afcd4b7c8c442c4d03e07649c24194b8e06
Author: Nishanth Menon <nm@ti.com>
Date:   Fri Aug 25 13:02:52 2023 -0500

    configs: am62x_evm_a53_defconfig: Switch to bootstd

and

commit ab54d9b28d8578cc43b214d39009e7b1def797e4
Author: Roger Quadros <rogerq@kernel.org>
Date:   Thu Oct 5 16:06:41 2023 +0300

    board: ti: am62x: am62x.env: Fix boot_targets
    
    ti_mmc is not a valid boot_target for standard boot flow so

I suppose TI's BSP still uses older U-Boot and is still not affected.
Do we need uEnv.txt now? Do you have an idea which distro Nishanth may
have tested with BOOTSTD change?
