My opinion was that we should not touch m25p80.c because:
(1)  As m25p80 is already working for various vendors. So unless multiple
   platforms start using SPI NOR framework, m25p80.c should remain untouched.
(2) we should not clutter header file with vendor specific op-codes as used in m25p80.
   I was of the opinion that instead of hard-coding the vendor specific info as
   MACROs, such information should be taken from DT or platform-data.

However, this was my thought during initial versions of SPI NOR patches.
But now if you think that SPI NOR is stable enough that same header info
can be reused without conflicts, then no problems.

(Apologies to Huang Shijie for re-work :-) ).

with regards, pekon
