356 help
357 Some U-Boot pointers have redundant information, so we can use a
358 scheme where we can return either an error code or a pointer with the
359 same return value. The default implementation just casts the pointer
360 to a number, however, this may fail on platforms where the end of the
361 address range is used for valid pointers (e.g. 0xffffff00 is a valid
362 heap pointer in socfpga SPL).
363 For such platforms, this value provides an upper range of those error
364 pointer values - up to 'MAX_ERRNO' bytes below this value must be
365 unused/invalid addresses.

695 in the chosen node is set to point to the correct serial node.
696 This option currently references CONFIG_CONS_INDEX, which is
697 incorrect when used with device tree as this option does not
698 exist / should not be used.

703 The old configuration infrastructure (= mkconfig + boards.cfg)
Masahiro Yamadaed363232014-09-16 16:32:58 +0900704 provided the extra options field. If you have something like
Masahiro Yamada51631252014-07-30 14:08:15 +0900705 "HAS_BAR,BAZ=64", the optional options
706 #define CONFIG_HAS
707 #define CONFIG_BAZ 64
708 will be defined in include/config.h.
709 This option was prepared for the smooth migration from the old
710 configuration to Kconfig. Since this option will be removed sometime,
711 new boards should not use this option.
