This is useful if there's 171# some common place where a few headers are being kept for a group 172# of devices. For example, device/<vendor>/common/kernel-headers could 173# contain some headers for several of <vendor>'s devices. 174# 175# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance 176# graph. This allows architecture products to provide headers for the 177# devices using that architecture. For example, 178# hardware/ti/omap4xxx/omap4.mk will specify 179# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4 180# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers. 181# The build system then combines all the values specified by all the 182# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance 183# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable. 184# 185# The layout of subdirs in any of the kernel-headers dir should mirror the 186# layout of the kernel include/ directory.

Additionally, the original kernel 193# headers must also be checked in, but in a different subdirectory.
