48 - [GENERIC]
53 - [DEFAULT]
55 Default functions provide hardware related functionality which is
57 replaced by the board driver if necessary. Those functions are called
58 via pointers in the NAND chip description structure. The board driver
59 can set the functions which should be replaced by board dependent

71 - [INTERN]
77 - [REPLACEABLE]
79 Replaceable members hold hardware related functions which can be
80 provided by the board driver. The board driver can set the functions
81 which should be replaced by board dependent functions before calling
86 - [BOARDSPECIFIC]
88 Board specific members hold hardware related information which must
89 be provided by the board driver. The board driver must set the
