 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.

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

 193 # The layout of subdirs in any of the kernel-headers dir should mirror the
