 176 #       explicitly set by anyone, the build system always adds this subdir.
 177 #
 178 #   TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
 179 #       to allow other directories to be included. This is useful if there's
 180 #       some common place where a few headers are being kept for a group
 181 #       of devices. For example, device/<vendor>/common/kernel-headers could
 182 #       contain some headers for several of <vendor>'s devices.
 183 #
 184 #   TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
 185 #       graph. This allows architecture products to provide headers for the
 186 #       devices using that architecture. For example,
 187 #       hardware/ti/omap4xxx/omap4.mk will specify
 188 #       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
 189 #       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.

 191 #       PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
 192 #       tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
