platform_build/core/config.mk
Ying Wang 157a5e1695 Load only the current product config makefile.
To reduce the start time.
With the change and previous change of doing clean step in only given paths,
start time of mm/mmm is reduced from ~5s to about 1s;
lunch time is reduced from ~40s to 3.5s.

# The build system exposes several variables for where to find the kernel

# TARGET_DEVICE_KERNEL_HEADERS is automatically created for the current
# device being built. It is set as $(TARGET_DEVICE_DIR)/kernel-headers,
# e.g. device/samsung/tuna/kernel-headers. This directory is not
# explicitly set by anyone, the build system always adds this subdir.
#
# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
# to allow other directories to be included. This is useful if there's
# some common place where a few headers are being kept for a group
# of devices. For example, device/<vendor>/common/kernel-headers could
# contain some headers for several of <vendor>'s devices.
#
# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
# graph. This allows architecture products to provide headers for the
# devices using that architecture. For example,
# hardware/ti/omap4xxx/omap4.mk will specify
# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
# The build system then combines all the values specified by all the
# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
#
# The layout of subdirs in any of the kernel-headers dir should mirror the
# layout of the kernel include/ directory. For example,
# device/samsung/tuna/kernel-headers/linux/,
# hardware/ti/omap4xxx/kernel-headers/media/,
# etc.
#
# NOTE: These directories MUST contain post-processed headers using the
# bionic/libc/kernel/clean_header.py tool. Additionally, the original kernel
# headers must also be checked in, but in a different subdirectory. By
# convention, the originals should be checked into original-kernel-headers
# directory of the same parent dir. For example,
# device/samsung/tuna/kernel-headers <----- post-processed
