This adds support for the IOT2050 Basic and Advanced devices. The Basic used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS quad-core version. Both variants are booted via a Siemens-provided FSBL that runs on the R5 cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot SPL, ATF and TEE have to reside in SPI flash. Full integration into a bootable image can be found on https://github.com/siemens/meta-iot2050 Based on original board support by Le Jin, Gao Nian and Chao Zeng.
