    gemini: select CONFIG_BLK_DEV_LOOP
    
    The gemini is using split squashfs/jffs2 root filesystems on
    all devices, so without CONFIG_BLK_DEV_LOOP the device does
    not gain a writeable root filesystem with these boot messages:
    
    mount_root: unable to create loop device
    mount_root: jffs2 not ready yet, using temporary tmpfs overlay
    
    and then it never gets out of that. Fix this so we get writeable
    rootfs again.
