Allows specific build options to be added to or
removed from the CFLAGS list when building this library.
CYGSEM_IO_NAND_DEBUG
This is the master switch for all debug reporting from the library.
CYGSEM_IO_NAND_DEBUG_FN_DEFAULT
This is the default function that the library will use when sending
debugging output. It must behave like printf.
The default - cyg_nand_defaultprintf
- is a wrapper to diag_printf.
Note: Individual drivers may override this setting in their
devinit routines by overwriting the pointer in
the device struct.
CYGSEM_IO_NAND_DEBUG_LEVEL
Specifies the verbosity of the NAND library and device drivers.
Ranges from 0 (off) to 9 (incredibly verbose); the default setting is 1.
(Higher values are only likely to be of use during driver development,
if ever.)
When enabled, messages are printed using the per-device printf-like
function (see above).
Note: Should a serious problem be encountered it will always
be reported the printf-like function, regardless of this
setting. Such messages may be suppressed altogether by turning
off CYGSEM_IO_NAND_DEBUG.
CYGSEM_IO_NAND_READONLY
Globally disables all code which writes to NAND devices.
This may be useful during driver development.
CYGNUM_NAND_MAX_PARTITIONS
Sets a compile-time limit on the number of partitions
any NAND device may have. The default is 4, which should be enough for
most purposes; unnecessarily setting this higher wastes RAM.
CYGSEM_IO_NAND_USE_BBT
Globally enables and disables the use of Bad Block Table.
Warning
This setting should not be disabled lightly!
It is strongly recommended that you leave this setting enabled unless
you have a very good reason to not use it. It is provided really as a
convenience for allowing developers to recover their NAND from a
confused state.
