 165 #       explicitly set by anyone, the build system always adds this subdir.

 168 #       to allow other directories to be included. This is useful if there's

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

 174 #       graph. This allows architecture products to provide headers for the
 175 #       devices using that architecture. For example,
 176 #       hardware/ti/omap4xxx/omap4.mk will specify
 177 #       PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
 178 #       specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
