Can cfi_cmdset.c functions be called by anybody?

Can cfi_cmdset.c functions be called by anybody?

[Derek Ross]

Hello,

Part of our flash application will be a real-time
logger.  The real time component will be limited
to certain periods of operation, but when it's running,
it will require about 5 bytes/second to be written
to a fixed circular buffer.

This would be simplified if I were able to directly
use the functions from cfi_cmdset_0001.c.

Are the functions available for any application to
use, or are they only available for device drivers?

Thanks,
Derek Ross.

The read/write/erase functionality of the chip driver is presented to 
userspace via the /dev/mtd[0123...] devices. Read and write work as 
expected, and there's an ioctl to perform an erase.

Would it be possible for me to modify, or
add to, the function pointers in the mtd_info
struct, so there there are also non-blocking 
write and erase functions?

Thanks,
Derek.
