It is set as $(TARGET_DEVICE_DIR)/kernel-headers, 168# e.g. device/samsung/tuna/kernel-headers. This directory is not 169# explicitly set by anyone, the build system always adds this subdir. 170# 171# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file 172# to allow other directories to be included. This is useful if there's 173# some common place where a few headers are being kept for a group 174# of devices. For example, device/<vendor>/common/kernel-headers could 175# contain some headers for several of <vendor>'s devices. 176# 177# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 178# graph. This allows architecture products to provide headers for the 179# devices using that architecture. For example, 180# hardware/ti/omap4xxx/omap4.mk will specify 181# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 182# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 183# The build system then combines all the values specified by all the 184# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 185# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 186# 187# The layout of subdirs in any of the kernel-headers dir should mirror the 188# layout of the kernel include/ directory.

Additionally, the original kernel 195# headers must also be checked in, but in a different subdirectory.
