pmaports/device/linux-sony-amami/APKBUILD

# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - package: just install zImage-dtb 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/aosp_rhine_amami_defconfig
# - enable devtmpfs (needed for udev -> touch support in weston)
# - change compression from CONFIG_KERNEL_LZMA=y to
#	CONFIG_KERNEL_GZIP=y (so it works with busybox)
# - disable proprietary graphics driver
