Some of the SPI device drivers at drivers/spi not a real
spi controllers, Unlike normal/generic SPI controllers they
operates only with SPI-NOR flash devices. these were technically
termed as SPI-NOR controllers, Ex: drivers/spi/fsl_qspi.c
The problem with these were resides at drivers/spi is entire
SPI layer becomes SPI-NOR flash oriented which is absolutely
a wrong indication where SPI layer getting effected more with
flash operations - So this SPI-NOR core will resolve this issue
by separating all SPI-NOR flash operations from spi layer and
creats a generic layer called SPI-NOR core which can be used to
interact SPI-NOR to SPI driver interface layer and the SPI-NOR
controller driver. The idea is taken from Linux spi-nor framework.
Before SPI-NOR:
-----------------------
cmd/sf.c
-----------------------
spi_flash.c
-----------------------
sf_probe.c
-----------------------
spi-uclass
-----------------------
spi drivers
-----------------------
SPI NOR chip

After SPI-NOR:
------------------------------
cmd/sf.c
------------------------------
spi-nor.c
-------------------------------
m25p80.c spi nor drivers
-------------------------------
spi-uclass SPI NOR chip
-------------------------------
spi drivers

SPI NOR chip

SPI-NOR with MTD:
------------------------------
cmd/sf.c
------------------------------
MTD core
------------------------------
spi-nor.c
-------------------------------
m25p80.c spi nor drivers

spi-uclass SPI NOR chip

SPI NOR chip
-------------------------------
drivers/mtd/spi-nor/spi-nor.c: spi-nor core
drivers/mtd/spi-nor/m25p80.c: mtd uclass driver
which is an interface layer b/w spi-nor core drivers/spi
drivers/mtd/spi-nor/fsl_qspi.c: spi-nor controller driver(mtd uclass)
Changes for v7:
- Rebase to latest
- Fixed git bisectable issues, with buildman.
- Fixed spi-nor compilation issues
- newly designed changes.
Changes for v6:
- Fixed git bisectable issues, with buildman.
- Fixed spi-nor compilation issues
- newly designed changes.
Changes for v5:
- newly designed changes
Testing:
$ git clone git://git.denx.de/u-boot-spi.git
$ cd u-boot-spi
