mtd: CFI 1.0 and CFI 1.1
This patch allows otpinfo for CFI >= 1.0 and burst read for CFI >= 1.1. references: 1.0: http://www.datasheetcatalog.org/datasheets2/81/816884_1.pdf 1.1: http://milkymist.org/doc/MT28F640J3.pdf http://www.delorie.com/agenda/specs/29066709.pdf Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
