[U-Boot-Users] [PATCH] Fixed cfi flash read uchar bug.

[wei.zhang at freescale.com]

From: Zhang Wei <wei.zhang at freescale.com>

For the flash of port width more than 8bit, a completetly read must be performed. For example, 16bit port width flash must perform a ushort read. Otherwise, some flashes will get error data.
