Do you mean the patch set from Jagan for rockchip platform to using binman?

That patch is actually using the output of the u-boot.itb which is based 
on this script.

I think Heiko and you has a discussion about this in previous version 
The U-Boot project build output is: tpl.bin, spl.bin, u-boot.bin
For rockchip platform, package needs:
- pack tpl.bin+spl.bin with mkimage -rksd/rkspi into idbloader.img
- get ATF binaries from bl31.bin/optee.bin with a script
- generate u-boot.its to describe the u-boot.itb
- pack u-boot.bin and ATF/OPTEE binaries into u-boot.itb with mkimage -f 

Does the binman mainly target for pack the idbloader.img+u-boot.itb?
