It is set as $(TARGET_DEVICE_DIR)/kernel-headers, 174# e.g. device/samsung/tuna/kernel-headers. This directory is not 175# explicitly set by anyone, the build system always adds this subdir. 176# 177# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file 178# to allow other directories to be included. This is useful if there's 179# some common place where a few headers are being kept for a group 180# of devices. For example, device/<vendor>/common/kernel-headers could 181# contain some headers for several of <vendor>'s devices. 182# 183# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 184# graph. This allows architecture products to provide headers for the 185# devices using that architecture. For example, 186# hardware/ti/omap4xxx/omap4.mk will specify 187# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 188# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 189# The build system then combines all the values specified by all the 190# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 191# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 192# 193# The layout of subdirs in any of the kernel-headers dir should mirror the 194# layout of the kernel include/ directory.
