> To implement initramfs bundled kernel packaging.
>
> The kernel images are copied from DEPLOY_DIR_IMAGE, and a list of
> packages will be generated according to KERNEL_IMAGETYPES setting.
>
> For instance:
> For KERNEL_IMAGETYPES = "bzImage vmlinux"
>
> the generated packages would be:
> - kernel-initramfs (Base package, RDEPENDS on kernel-initramfs-image)
> - kernel-initramfs-image (Image package, RDEPENDS on all sub images)
> - kernel-initramfs-image-bzimage (Contains bzImage image)
> - kernel-initramfs-vmlinux (Contains vmlinux image)
>
> This recipe would be skipped if INITRAMFS_IMAGE_BUNDLE or
> INITRAMFS_IMAGE is not being set correctly.
