i.MX8 Platform

  • Add support for OSM-S/BL i.MX8MP hardware
  • Add a solution for fw_getenv/setenv to automatically use the environment on the device that is used by the bootloader.
  • Move the U-Boot environment on the eMMC hardware partition (boot0) to the end of the partition.

i.MX6 Platform

  • Add support for DPI display interface on BL boards (configuration imx6ull-kontron-dl)
  • U-Boot: Change default device tree boot configuration from imx6ul-kontron-bl to imx6ull-kontron-dl
  • Linux: Changes in kernel config
  • Virtual terminals deactivated (CONFIG_VT)
  • Most resistive touch drivers removed

Changes for STM32MP1 Platform

  • none

Breaking Changes

  • i.MX6: Default u-boot configuration changed from SOC ul variant to ull variant. So for ul variants the boot config has to be adapted manually in u-boot environment now!
  • The location of the environment on the eMMC of i.MX8MM devices is moved to the end of the boot0 hardware partition.

Known Issues

  • The onboard USB hub on the BL i.MX8MM doesn't work in U-Boot.
  • Devices connected to the USB-C connector of the BL i.MX8MP before booting up the board are not detected and need to be reconnected after booting.
