[Buildroot] genimage raw partition from multiple files

Hi,

I've been trying to figure out, how to create raw partition, without
filesystem, from 2 or more files. Here is a general idea


partition uboot {
    partition-type = 0xa2
    size = 1M

    image spl {
        image = "u-boot-spl.bin.crc"
	size = 64k
        offset = 0
    }

    image uboot-real {
        image = "u-boot.bin"
        offset = 256k
    }
}


Note that spl is 64k big, and uboot-real must be at offset 256k. Also
this *MUST* be a partition of type 0xa2. Can such thing be done fully in
genimage without post-install script?
