Changelog

Rev.0054

BSP

  • Prepare support for Vision Components GmbH MIPI CSI cameras
    • Add dvice trees
    • Add “camera” MACHINE_FEATURE

Linux

  • Add devicet rees for Vision Components GmbH MIPI CSI cameras

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
    • Replace hard assignments to IMAGE_BOOT_FILES with ?=
