[U-Boot] FDT on second address of android image

[U-Boot] FDT on second address of android image

[Michael Trimarchi]

This is not a patch, but just an idea of what I would like
to have. I don't know what is the best option to change
the image-fit file. So I have just tried because the boot_get_fdt
start to be a very long function and would make sense to split
in some way.
There are two point where make sense to insert this code in my
opinion. As you can see here or complicated this condition

  } else if (images->legacy_hdr_valid &&
                        image_check_type(&images->legacy_hdr_os_copy,
                                         IH_TYPE_MULTI)) {

I don't test it so far. Anyway, I have seen that some android
image (aka fsl) use this address.
