Greetings,
I'm taking a look at moving imx8mm-venice to use binman for packaging.
After doing so U-Boot proper fails to boot:

Any ideas what this could be?
My patch in case I'm missing something obvious is:

A follow-on question is that I would like to investigate using binman
in the SPL to dynamically access the IMX8M ddr training blobs so that
we don't have to waste padding space taking them onto the end of the
SPL which is currently done. The lpddr4 training blobs I'm using
currently take up 57k without padding compared to 81k with padding.
The location of them is handled in ddr_load_train_firmware.
If I add the following to my SPL:

I get 'blob_1:0x0' which is not what I expected.
If I understand correctly binman is using linker symbols to determine
where things are in the image? What I don't quite understand is what
symbols are valid to use assuming my dtsi above. The binman.rst docs
talk use 'u_boot_any' as an example which apparently can match
'u-boot.bin', 'u-boot.img', and 'u-boot-nodtb.bin' but I can't find
the code that somehow translates this meaning.
Best regards,
Tim
