I wanted to build the fsl dts in my machine and found that
the dtb have not extra space,so uboot will cause about
FDT_ERR_NOSPACE issue.

How do we not have issues with arm and arm64 boards which don't have
padding? Or what took so long to notice on powerpc?

I guess that was missed in 1acf1cf8638a ("powerpc: build .dtb files in dts directory").

Which I think means the assignment to DTC_FLAGS in
arch/powerpc/boot/Makefile is not needed anymore.

Can you send a v2 removing that assignment and explaining that's what
happened?

I've wanted to make this common, but I guess that's a separate change.
