Buildroot already sets those options when building a kernel with BR2_TARGET_ROOTFS_INITRAMFS=y in the Buildroot configuration. See linux/linux.mk, and search for BR2_TARGET_ROOTFS_INITRAMFS.

At the time of submission, the Mainline kernel does not currently support the STM32f469. This patch makes changes to the defconfig to enable booting with the CPIO which Buildroot puts together.
