# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - package: just install zImage and kernel.release, because the kernel config
#	does not generate modules or dtb files
# - do not create -dev subpackage (makes no sense without module support)
#
# Kernel config changes, based on: arch/arm/configs/fusion3_yuga_defconfig
# - enable devtmpfs (needed for udev -> touch support in weston)
# - set CONFIG_USB_ETH=y and CONFIG_USB_ETH_RNDIS=y (needed for ethernet over USB (rndis))
# - disable ANDROID_PARANOID_NETWORK (removes network restrictions)
