Subject: [PATCH] Find correct manufacture ID
Date: Wed, 16 Feb 2005 18:10:58 +0900 [thread overview]
Message-ID: <0IBZ008IQYUAKZ@mmp1.samsung.com> (raw)
If you find 8-bit buswidth flash with 16-bit buswidth option, it
displays warning message.
Before display you have to find correct manufacture ID.
