This option has crept into use with some boards. Add a warning to try to prevent this.
As an example: https://lists.denx.de/pipermail/u-boot/2017-September/304966.html
We have just discussed this in another thread. There seem to be ~109 defconfigs in the tree that enable OF_EMBED.
I doubt all of them do this for fun, so we might want to collect the reasons they do so. I do know two:
- socfpga_stratix10_defconfig needs this to get a correct u-boot-spl.hex - I would need it to ensure in SPL, the DTB is in one block with the other readonly parts. Without OF_EMBED, we have '.text', '.bss', DT.
