# setting the KERNEL_TREE environment variable changes the source
# location and updates the pkgver accordingly
#
# currently the following valuse for KERNEL_TREE are supported:
# - mainline - latest stable linux kernel release with alpine's config
#
# - asahi - latest asahi kernel from git with config taken form their PKGBUILD
# repo
#
# - rpi - latest raspberry pi kernel release with defconfig
#
# - visionfive - latest starfive-tech kernel from the vision five branch with
# visionfive_defconfig
#
# - megi - latest megi kernel with pinephone_pro_defconfig
#
# TODO:
# add KERNEL_CONFIG option to override config used when compiling
