I sent a patch to make binman report this as an error.

I pushed the resulting tree to:

https://github.com/sjg20/u-boot/tree/try-tim

Now the error is:

binman: Section '/binman/u-boot-spl-ddr': Symbol
'_binman_u_boot_any_prop_image_pos'

   in entry '/binman/u-boot-spl-ddr/u-boot-spl/u-boot-spl-nodtb':
Entry 'u-boot-any' not found in list
(u-boot-spl-nodtb,u-boot-spl-dtb,u-boot-spl,blob-ext at 1,blob-ext at 2,blob-ext at 3,blob-ext at 4,main-section)

The problem seems to be that you are asking binman to generate three
independent images. U-Boot is in a FIT which is not in the same image
as SPL. So it is not possible to locate the flash offset of U-Boot
(with in the FIT).

Can you give me a bit more info about your intent here? Is it to load
U-Boot from the FIT? I so, I suppose it is possible to make binman
access an independent image, if it is told where it starts.

But why is everything not in one image?

Simon
