(Almost) flushing our upstream queue for the IOT2050 device, this mostly brings board-specific changes such as:
- updated build process and firmware layout for PG1 vs. PG2 devices - more watchdog preparations - preparations for verified boot on IOT2050 Advanced devices
This series depends on
https://lore.kernel.org/u-boot/cover.1675426972.git.jan.kiszka@siemens.com/ ("env: Enhancements for establishing variable protection")
Changes in v5: - factored out two patches
Changes in v4: - rebased over latest master - make use of new CONFIG_EFI_SCROLL_ON_CLEAR_SCREEN
Changes in v3: - further reworked patch 1 to load default env directly, leaving driver ordering alone
Changes in v2: - rebased over latest master - reworked patch 1 to be less invasive to the code - added "iot2050: use the named gpio to control the user-button"
Still in our backlog is support for a new variant that comes with M.2 slots. Related DT patches were sent to the kernel and are under review now.
