Who: Lee, Chun-Yi <jlee@novell.com>

+----------------------------
+What: The XFS nodelaylog mount option
+When: 3.3
+Why: The delaylog mode that has been the default since 2.6.39 has proven
+ stable, and the old code is in the way of additional improvements in

+WARNING: Do not access chip registers using the i2cdump command, and do not use
+any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
+supported by this driver interpret any access to a command register (including
+read commands) as request to execute the command in question. This may result in
+power loss, board resets, and/or Flash corruption. Worst case, your board may

+ This options enables the workaround for the 364296 ARM1136
