 185 #
 186 #   TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
 187 #       to allow other directories to be included. This is useful if there's

 193 #       graph. This allows architecture products to provide headers for the
 194 #       devices using that architecture. For example,

 196 #       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
 197 #       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
