Timing issue when we use SPANSION 8MB Flash

[李威震]

hi,
I find the discussion with the same subject in the past,
http://www.infradead.org/pipermail/linux-mtd/2005-October/013996.html
but it's without worth suggestion.
Now we have more the same situation.
We use linux kernel 2.4.19-rmk4-2.17 which is chipset vendor provided.
The target board arch is arm920t. There is  SPANSION 8MB Nor Flash
(S29GL064A90TFIR7) on the board.
we use root file system with jffs2 format on the nor flash.
The problem is copying the file to /dev/mtd# or the file system will take 
very long time(around 15 min for 4.5 MB). 
any suggestion for this iussue?
