You are referring to obsolete code.

All this stuff has been moved into what is  now  called  the  "legacy
NAND  driver"  code,  which will be removed sometime (hopefully) soon
(as soon as board maintainers convert5ed hteir boards to use the  new
NAND code).

Please get a current version of U-Boot (top of  repository)  and  use
this for any recent work.

Best regards,
