 187 #       explicitly set by anyone, the build system always adds this subdir.
 188 #
 189 #   TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
 190 #       to allow other directories to be included. This is useful if there's

 192 #       of devices. For example, device/<vendor>/common/kernel-headers could

 194 #
 195 #   TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
 196 #       graph. This allows architecture products to provide headers for the
 197 #       devices using that architecture. For example,
 198 #       hardware/ti/omap4xxx/omap4.mk will specify
 199 #       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
 200 #       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
