This is useful if there's 172# some common place where a few headers are being kept for a group 173# of devices. For example, device/<vendor>/common/kernel-headers could 174# contain some headers for several of <vendor>'s devices. 175# 176# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 177# graph. This allows architecture products to provide headers for the 178# devices using that architecture. For example, 179# hardware/ti/omap4xxx/omap4.mk will specify 180# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 181# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 182# The build system then combines all the values specified by all the 183# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 184# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 185# 186# The layout of subdirs in any of the kernel-headers dir should mirror the 187# layout of the kernel include/ directory.

Additionally, the original kernel 194# headers must also be checked in, but in a different subdirectory.
