  • Update sub modules to support hardknott
  • Port TQMa8 boards from branch zeus-tqma8 (equal to release zeus.TQMa8.BSP.SW.0056 of mentioned branch)
  • Weak assignments in machine files wherever possible to allow overwriting for custom mainboards or project specific tailoring

U-Boot

Linux

  • Linux 5.10 support based on linux-fslc 5.10 + imx
    • experimental usb support for ath10k
    • adjusted kernel config settings

  • Enable building multiple u-boot configs

U-Boot

  • Support multiple u-boot configs. Build all bootstream variants for all enabled u-boot configs

Rev.0052

BSP

  • Sanitize variable assignments to improve reusability in config/machines:
    • Replace IMAGE_INSTALL_append with more approbiate MACHINE_EXTRA_RRECOMMENDS_append
    • Remove all dirty magic for DISTRO_FEATURES_remove
