# Common include file that defines AGL's variables for kernel
# configuration.
#
# Can be included directly for kernel.bbclass based recipes that
# use their own config fragment merging scheme, or use the
# KERNEL_CONFIG_FRAGMENTS variable (e.g. meta-ti, meta-qcom).
#
# Fragments should be added to AGL_KCONFIG_FRAGMENTS as just the
# .cfg filename with +=.  Appending to AGL_KCONFIG_FRAGMENTS (i.e.
# using _append) should only be done for:
# - Specific AGL features that set an override in their feature
#   template, e.g. agl-netboot.
# - To add essential configuration for core target machines like
#   qemu.  Note that appending fragments directly to SRC_URI
#   would work for qemu targets since they use linux-yocto, but
#   the AGL_KCONFIG_FRAGMENTS mechanism is recommended for
#   consistency and to preserve the option of disabling all AGL
#   additions by overriding AGL_KERNEL_SRC.
#
# In general, care shoud be taken to preserve the ability to set
# AGL_KCONFIG_FRAGMENTS to "" to disable non-essential (from a build
# perspective) AGL additions.
