1# Use this file to generate dtb.img and dtbo.img instead of using 2# BOARD_PREBUILT_DTBIMAGE_DIR. We need to keep dtb and dtbo files at the fixed 3# positions in images, so that bootloader can rely on their indexes in the 4# image. As dtbo.img must be signed with AVB tool, we generate intermediate 5# dtbo.img, and the resulting $(PRODUCT_OUT)/dtbo.img will be created with 6# Android build system, by exploiting BOARD_PREBUILT_DTBOIMAGE variable. 7 8ifneq ($(filter yukawa%, $(TARGET_DEVICE)),) 9 10MKDTIMG := system/libufdt/utils/src/mkdtboimg.py 11DTBIMAGE := $(PRODUCT_OUT)/dtb.img 12DTBOIMAGE := $(PRODUCT_OUT)/$(DTBO_UNSIGNED) 13 14# Please keep this list fixed: add new files in the end of the list 15DTB_FILES := \ 16 $(LOCAL_DTB)/meson-sm1-khadas-vim3l.dtb \ 17 $(LOCAL_DTB)/meson-g12b-a311d-khadas-vim3.dtb 18 19# Please keep this list fixed: add new files in the end of the list 20DTBO_FILES := \ 21 $(LOCAL_DTB)/meson-sm1-khadas-vim3l-android.dtb \ 22 $(LOCAL_DTB)/meson-g12b-a311d-khadas-vim3-android.dtb 23 24$(DTBIMAGE): $(DTB_FILES) 25 cat $^ > $@ 26 27$(DTBOIMAGE): PRIVATE_MKDTIMG := $(MKDTIMG) 28$(DTBOIMAGE): PRIVATE_DTBO_FILES := $(DTBO_FILES) 29$(DTBOIMAGE): $(DTBO_FILES) $(MKDTIMG) 30 $(PRIVATE_MKDTIMG) create $@ $(PRIVATE_DTBO_FILES) 31 32include $(CLEAR_VARS) 33LOCAL_MODULE := dtbimage 34LOCAL_LICENSE_KINDS := legacy_restricted 35LOCAL_LICENSE_CONDITIONS := restricted 36LOCAL_ADDITIONAL_DEPENDENCIES := $(DTBIMAGE) 37include $(BUILD_PHONY_PACKAGE) 38 39include $(CLEAR_VARS) 40LOCAL_MODULE := dtboimage 41LOCAL_LICENSE_KINDS := legacy_restricted 42LOCAL_LICENSE_CONDITIONS := restricted 43LOCAL_ADDITIONAL_DEPENDENCIES := $(DTBOIMAGE) 44include $(BUILD_PHONY_PACKAGE) 45 46droidcore: dtbimage dtboimage 47 48$(call dist-for-goals, dist_files, $(DTBOIMAGE)) 49 50endif 51
