Need to enablt CONFIG_OF_EMBED if we use separate uboot and dtb
in FIT image for SPL loading.
Can you please explain that a bit more? We shouldn't OF_EMBED in
production code, only for debug/test.
When I test with latest code for SPL loading FIT which u-boot and dtb
are separate, the U-Boot code can not find its dtb file.
This issue is not happen when I test with code older than v2017.03,
and with CONFIG_OF_EMBED, U-Boot can find dtb with latest code.
Maybe I need to do some debugging for root cause, please ignore this
patch if this is not correct.
Yes this needs to be figured out. If you have the debug UART enabled
you should be able to add debugging to fdtdec_setup() to see what is
happening. Perhaps the DT is not word-aligned?
I find the root cause.
I try to truncate the input image like uboot-no-dtb.bin and u-boot.dtb to
block size 512, so the SPL get the image size is 512 aligned,
but the fdtdec_setup() using the end of image address &_end which is not
512 aligned, and can not find available dtb.
I want to make the mkimage output header and input image aligned to
512 to reduce no necessary copy.

Run make savedefconfig to make the options order correct.
