This is useful for people who have not moved the microcode.  Are we going to ensure that everyone who updates U-Boot will also move their microcode to the new location?  We can always revert this patch after everyone has migrated, if that's really necessary.

You know as well as I do that if don't provide backwards compatibility, someone is going to break and won't know why.

No.  The warning just says that microcode is invalid, not that that it's at the wrong address.
