build: support a new image u-boot-dtb.img
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.
