# 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/titan_defconfig
# Changes:
# - enable devtmpfs (needed for udev -> touch support in weston)
