--- Comment #1 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com> ---
Indeed, linux/linux.mk contains:

        $(if $(BR2_TARGET_ROOTFS_CPIO),
                $(call KCONFIG_ENABLE_OPT,CONFIG_BLK_DEV_INITRD,$(@D)/.config))

Which forces CONFIG_BLK_DEV_INITRD to be set when you're generating a cpio
image of the filesystem.

What is your use-case for generating a cpio image, but not enabling
CONFIG_BLK_DEV_INITRD ?
