I think he want to say here is that it needs "console=" which
is indicated by Geert on https://patchwork.kernel.org/patch/5184001/

	"Note that we have to keep the "console=ttySC1" parameter in
	chosen/bootargs, ..."

I don't have armadillo800eva anymore, so I can't test this patch.
But according to Phuc-san, there is not command prompt after boot
without this patch.
