This is necessary, as ppc4xx has the reset vector located at the end of the U-Boot image. This needs to be flashed to the end of the NOR flash. Adding the dtb to the main U-Boot image will break booting on ppc4xx. This patch now embeds the dtb in the U-Boot image instead.

It this a common requirement for PowerPC architecture?
No. Its specific to PPC4xx, and perhaps some other PPC variants. But not generally for PowerPC.
If so, does it make sense to change default value only for PowerPC?
Might make sense. Or perhaps even for PPC4xx?
choice prompt "Provider of DTB for DT control" depends on OF_CONTROL default OF_EMBED if PPC
default OF_EMBED if 4xx
Does this work?
Thanks, Stefan
