In order to maintain compatibility with older trees, we now have minadbd.old and minui.old. I had to use a TARGET_GLOBAL_CFLAG to handle ifdef issues in minui/minui.d because healthd includes minui/minui.h and there was no other alternative to make minui.h compatible with older trees without having to modify healthd rules which is outside of TWRP. Note that the new minui does not currently have support for qcom overlay graphics. Support for this graphics mode will likely be added in a later patch set. If you are building in a 6.0 tree and have a device that needs qcom overlay graphics, be warned, as off mode charging may not work properly. A dead battery in this case could potentially brick your device if it is unable to charge as healthd handles charging duties. Update rules for building toolbox and add rules for making toybox Use permissive.sh in init.rc which will follow symlinks so we do not have to worry about what binary is supplying the setenforce functionality (toolbox, toybox, or busybox). Fix a few warnings in the main recovery binary source code. Fix a few includes that were missing that prevented compiling in 6.0 Change-Id: Ia67aa2107d260883da5e365475a19bea538e8b97
