623 depends on OF_LIBFDT
624 help
625 This uses U-Boot's serial alias from the aliases node to update
626 the device tree passed to the OS. The "linux,stdout-path" property
627 in the chosen node is set to point to the correct serial node.
628 This option currently references CONFIG_CONS_INDEX, which is
629 incorrect when used with device tree as this option does not
630 exist / should not be used.
632 config SYS_EXTRA_OPTIONS
633 string "Extra Options (DEPRECATED)"
634 help
635 The old configuration infrastructure (= mkconfig + boards.cfg)
636 provided the extra options field. If you have something like
637 "HAS_BAR,BAZ=64", the optional options
638 #define CONFIG_HAS
639 #define CONFIG_BAZ 64
640 will be defined in include/config.h.
641 This option was prepared for the smooth migration from the old
642 configuration to Kconfig. Since this option will be removed sometime,
643 new boards should not use this option.
