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

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

 193 #

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

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