Add a new product configuration, how it works

1. add 3 files in device/companyName/deviceName

vendorsetup.sh AndroidProducts.mk BoardConfig.mk

2.vendorsetup.sh  (during "source build/envsetup.sh", it will search for vendorsetup.sh, and execute them)

add_lunch_combo full_myName-user  ---------------------------- Add an item in lunch menu
add_lunch_combo full_myName-userdebug
add_lunch_combo full_myName-eng
add_lunch_combo devpreview_myName-user
add_lunch_combo devpreview_myName-userdebug
add_lunch_combo devpreview_myName-eng
add_target_product_mapping devpreview_myName:full_myName  ---- map devpreview_myName to full_myName
add_def_config full_myName:tablet  ------------------  define the device's configuration (This value will be set toTARGET_BUILD_CONFIGURATION)

3. AndroidProducts.mk  (After user select a combo, it will search forAndroidProducts.mk in which has the definition of the selected combo)

PRODUCT_MAKEFILES := \
    full_myName:$(LOCAL_DIR)/tablet_full_myName.mk

The format of combo name is like "PRODUCT-BUILD_VARIANT", e.g. "full_myName-userdebug". After parsing this combo name, then

TARGET_PRODUCT=full_myName
TARGET_BUILD_VARIANT=userdebug

4. run tablet_full_myName.mk

$(call inherit-product, device/amazon/myName/myName.mk)
$(call inherit-product, device/amazon/swconfigs/tablet/tablet.mk)

5. look for BoardConfig.mk and run it

After running "tablet_full_myName.mk", we can get PRODUCT_DEVICE definition.

PRODUCT_DEVICE = myName

TARGET_DEVICE := $(PRODUCTS.$(INTERNAL_PRODUCT).PRODUCT_DEVICE)

Then it will look for */$(TARGET_DEVICE)/BoardConfig.mk in device(or vendor) folder.

6. How to see the result of Boardconfig.mk

Use printconfig function.

And we can customize the output by changing print_build_config_vars in/build/core/dumpvar.mk

7. include your own AndroidBoard.mk

During make, it will include AndroidBoard.mk to build kernel code.
