Hi Masahiro,

In SPL framework, SPL uses u-boot.img to load u-boot.bin. Here, u-boot.img = uImage header + u-boot.bin
To use OF control with a separate devicetree, u-boot.dtb must be placed right after u-boot.bin. In this case, u-boot-dtb.bin is generally used. Here, u-boot-dtb.bin = u-boot.bin + u-boot.dtb
We need u-boot-dtb.img to use both SPL framework and separate OF control at the same time. u-boot-dtb.img = uImage header + u-boot-dtb.bin
For example, Zynq boards already define all of
- CONFIG_SPL
- CONFIG_OF_CONTROL
- CONFIG_OF_SEPARATE
So, the support of u-boot-dtb.img is urgent.

FYI there is also a .lds file problem in some cases - see:
