board: siemens: Add support for SIMATIC IOT2050 devices 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.

iot2050: Add CFG_ENV_FLAGS_LIST_STATIC Will be needed when CONFIG_ENV_WRITEABLE_LIST is enabled. The listed variables shall remain writable, for informational purposes - they have to be considered untrusted because the persistent U-Boot env is not protected.

iot2050: Add support for configuring M.2 connector The M.2 slots of the related IOT2050 variant need to be configured according to the plugged cards. This tries to detect the card using the M.2 configuration pins of the B-key slot. If that fails, a U-Boot environment variable can be set to configure manually. This variable is write-permitted also in secure boot mode as it is not able to undermine the integrity of the booted system. The configuration is then applied to mux the serdes and to fix up the device tree passed to or loaded by the bootloader. The fix-ups are coming from device tree overlays that are embedded into the firmware image and there also integrity protected. The OS remains free to load a device tree to which they do not apply: U-Boot will not fail to boot in that case. Based on original patch by Chao Zeng.
