# my_boot_image_name: the boot image to install
# my_boot_image_arch: the architecture to install (e.g. TARGET_ARCH, not expanded)
# my_boot_image_out: the install directory (e.g. $(PRODUCT_OUT))
# my_boot_image_syms: the symbols director (e.g. $(TARGET_OUT_UNSTRIPPED))

# Output variables:
# my_boot_image_module: the created module name. Empty if no module is created.
