+# These config vars are usually set in BoardConfig.mk:
+#
+# TARGET_KERNEL_SOURCE = Kernel source dir, optional, defaults
+# to kernel/$(TARGET_DEVICE_DIR)
+# TARGET_KERNEL_ADDITIONAL_FLAGS = Additional make flags, optional
+# TARGET_KERNEL_ARCH = Kernel Arch
+# TARGET_KERNEL_CROSS_COMPILE_PREFIX = Compiler prefix (e.g. arm-eabi-)
+# defaults to arm-linux-androidkernel- for arm
+# aarch64-linux-androidkernel- for arm64
+# x86_64-linux-androidkernel- for x86
+#
+# TARGET_KERNEL_CLANG_COMPILE = Compile kernel with clang, defaults to false
+#
+# KERNEL_TOOLCHAIN_PREFIX = Overrides TARGET_KERNEL_CROSS_COMPILE_PREFIX,
+# Set this var in shell to override
+# toolchain specified in BoardConfig.mk
+# KERNEL_TOOLCHAIN = Path to toolchain, if unset, assumes
+# TARGET_KERNEL_CROSS_COMPILE_PREFIX
+# is in PATH
+# USE_CCACHE = Enable ccache (global Android flag)
