In the end I would like to create a "disk image" with _all_ the
content, and the data part must be populated at build time, as it
works at the moment.

Pseudo image:

image sdcard.img {
    hdimage {
    }

    partition u-boot {
        partition-type = 0xC
        bootable = "true"
                image = "boot.vfat"
    }

    partition rootfsA {
        partition-type = 0x83
        image = "rootfs.ext4"
        size = 512M
    }

    partition rootfsB {
        partition-type = 0x83
        image = "rootfs.ext4"
        size = 512M
    }

    partition data {
        partition-type = 0x83
        image = "data.ext4"
        size = 512M
    }
}
