+ This is the core SPI NOR framework which can be used to interact SPI-NOR
+ to SPI driver interface layer and the SPI-NOR controller driver.
+
+ Unlike normal/generic spi controllers, they are few controllers which are
+ exclusively used to connect SPI-NOR devices, called SPI-NOR controllers.
+ So technically these controllers shouldn't reside at drivers/spi as these
+ may effect the generic SPI bus functionalities, so this SPI-NOR core acts
+ as a common core framework between the generic SPI controller drivers vs
+ SPI-NOR controller drivers for SPI-NOR device access. Note that from SPI-NOR
+ core to SPI drivers there should be an interface layer.

Set up your spi devices with the right board-specific platform data,
if you want to specify device partitioning or to use a device which
doesn't support the JEDEC ID instruction.
