-# Android makefile to build kernel as a part of Android Build
-#
-# Configuration
-# =============
-#
-# These config vars are usually set in BoardConfig.mk:
-#
-#   TARGET_KERNEL_CONFIG               = Kernel defconfig
-#   TARGET_KERNEL_VARIANT_CONFIG       = Variant defconfig, optional
-#   TARGET_KERNEL_SELINUX_CONFIG       = SELinux defconfig, optional
-#   TARGET_KERNEL_ADDITIONAL_CONFIG    = Additional defconfig, optional
-#
-#   TARGET_KERNEL_CLANG_COMPILE        = Compile kernel with clang, defaults to false
-#
-#   TARGET_KERNEL_CLANG_VERSION        = Clang prebuilts version, optional, defaults to clang-stable
-#
-#   TARGET_KERNEL_CLANG_PATH           = Clang prebuilts path, optional
-#
-#   BOARD_KERNEL_IMAGE_NAME            = Built image name
-#                                          for ARM use: zImage
-#                                          for ARM64 use: Image.gz
-#                                          for uncompressed use: Image
-#                                          If using an appended DT, append '-dtb'
-#                                          to the end of the image name.
-#                                          For example, for ARM devices,
-#                                          use zImage-dtb instead of zImage.
-#
-#   BOARD_DTBO_CFG                     = Path to a mkdtboimg.py config file
-#
-#   BOARD_CUSTOM_DTBOIMG_MK            = Path to a custom dtboimage makefile
-#
-#   KERNEL_CC                          = The C Compiler used. This is automatically set based
-#                                          on whether the clang version is set, optional.
-#   KERNEL_LD                          = The Linker used. This is automatically set based
-#                                          on whether the clang/gcc version is set, optional.
-#
-#   KERNEL_CLANG_TRIPLE                = Target triple for clang (e.g. aarch64-linux-gnu-)
-#                                          defaults to arm-linux-gnu- for arm
-#                                                      aarch64-linux-gnu- for arm64
-#                                                      x86_64-linux-gnu- for x86
-#
-#   NEED_KERNEL_MODULE_ROOT            = Optional, if true, install kernel
-#                                          modules in root instead of vendor
-#   NEED_KERNEL_MODULE_SYSTEM          = Optional, if true, install kernel
