this code should be in the MTD code, not in the drivers.
I have spilted this code, please see patch 3 & patch 4.

Since there is no standard for SPI-NOR commands, we _should_ add new
code for
new chips with new opcodes. For example, if a new chip supports the
quad-read with
a new command 0xef, we can submit a small patch for m25p80 to fix it.

We have to do it in such way, no shortcut.
