This adds initial support for the Toradex Verdin AM62 Quad 1GB WB IT V1.0A module and subsequent V1.1 launch configuration SKUs. They are strapped to boot from their on-module eMMC. U-Boot supports booting from the on-module eMMC only, DFU support is disabled for now due to missing AM62x USB support. The device trees were taken straight from Linux v6.5-rc1. Boot sequence is: SYSFW ---> R5 SPL (both in tiboot3.bin) ---> ATF (TF-A) ---> OP-TEE ---> A53 SPL (part of tispl.bin) ---> U-boot proper (u-boot.img) Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Reviewed-by: Nishanth Menon <nm@ti.com>
