For example, device/<vendor>/common/kernel-headers could 168# contain some headers for several of <vendor>'s devices. 169# 170# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 171# graph. This allows architecture products to provide headers for the 172# devices using that architecture. For example, 173# hardware/ti/omap4xxx/omap4.mk will specify 174# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 175# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 176# The build system then combines all the values specified by all the 177# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 178# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 179# 180# The layout of subdirs in any of the kernel-headers dir should mirror the 181# layout of the kernel include/ directory.
