pmaports/device/linux-htc-bravo/APKBUILD

# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - add xz package (necessary to build)
#
# Kernel config based on: arch/arm/configs/bravo_defconfig
# Changes:
# - apply patches to compile with gcc6
# - enable devtmpfs (needed for udev -> touch support in weston)
# - enable udev required options (https://wiki.gentoo.org/wiki/Udev#Kernel)
