pmaports/device/linux-oneplus-bacon/APKBUILD

# APKBUILD based on linux-vanilla aport. Changes:
# - add !check !tracedeps
# - do not create -dev subpackage
# - add 'xz' and 'dtbtool' as build dependencies
# - add `dtbTool` build hook to generate separate 'dt.img'
#
# Kernel config based on: arch/arm/configs/lineageos_bacon_defconfig
# Changes:
# - enable loadable module support
# - enable devtmpfs (needed for udev -> touch support in weston)
# - enable virtual terminal
# - disable ANDROID_PARANOID_NETWORK (removes network restrictions)
