Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006110242000127] was created:

<snip>

This patch comes from Yuli's posted patch on 8/8/2006 titled "CFI Driver Little-Endian write Issue".

http://sourceforge.net/mailarchive/message.php?msg_id=36311999

If that patch applied, please discard this one.

Until now , I do not see his patch is applied. So please apply this one.
