In file system technical speak I think you mean mounting with noatime.
atime is updated when a file is accessed. This slows the file system. Thus, 
you can mount a file system with a noatime flag which prevents the flag from 
being updated whenever the file is read.

YAFFS does not support atime updating. Any time you mount yaffs it is 
equivalent to mounting with noatime.

YAFFS does however update file times when the files are written. The only way 
I can think of to get around this is to programmatically set the file update 
time after you have written the file.
