board driver if neccecary. Those functions are called via pointers in the
NAND chip description structure. The board driver can set the functions which
- should be replaced by board dependend functions before calling nand_scan().
+ should be replaced by board dependent functions before calling nand_scan().
If the function pointer is NULL on entry to nand_scan() then the pointer
is set to the default function which is suitable for the detected chip type.
