Linus Torvalds 9786e34e0a MTD updates for 4.12-rc1:
NAND, from Boris:
 """
  - some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
    davinci, brcmnand, omap)
  - a huge cleanup/rework of the denali driver accompanied with core
    fixes/improvements to simplify the driver code
  - a complete rewrite of the atmel driver to support new DT bindings
    make future evolution easier
  - the addition of per-vendor detection/initialization steps to avoid
    extending the nand_ids table with more extended-id entries
 """
 
 SPI NOR, from Cyrille:
 """
 - fixes in the hisi SPI controller driver.
 - fixes in the intel SPI controller driver.
 - fixes in the Mediatek SPI controller driver.
 - fixes to some SPI flash memories not supported the Chip Erase command.
 - add support to some new memory parts (Winbond, Macronix, Micron, ESMT).
 - add new driver for the STM32 QSPI controller.

tristate "ARM PL172 MPMC driver"
depends on ARM_AMBA && OF
help
This selects the ARM PrimeCell PL172 MultiPort Memory Controller.
If you have an embedded system with an AMBA bus and a PL172
controller, say Y or M here.
config ATMEL_SDRAMC
bool "Atmel (Multi-port DDR-)SDRAM Controller"
default y
depends on ARCH_AT91 && OF
help
This driver is for Atmel SDRAM Controller or Atmel Multi-port
DDR-SDRAM Controller available on Atmel AT91SAM9 and SAMA5 SoCs.
Starting with the at91sam9g45, this controller supports SDR, DDR and
LP-DDR memories.
config ATMEL_EBI
bool "Atmel EBI driver"
default y
depends on ARCH_AT91 && OF
select MFD_SYSCON
select MFD_ATMEL_SMC
help
Driver for Atmel EBI controller.
Used to configure the EBI (external bus interface) when the device-
tree is used. This bus supports NANDs, external ethernet controller,
SRAMs, ATA devices, etc.
config TI_AEMIF
tristate "Texas Instruments AEMIF driver"
depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
help
This driver is for the AEMIF module available in Texas Instruments
SoCs. AEMIF stands for Asynchronous External Memory Interface and
is intended to provide a glue-less interface to a variety of
asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
of 256M bytes of any of these memories can be accessed at a given
time via four chip selects with 64M byte access per chip select.
config TI_EMIF
tristate "Texas Instruments EMIF driver"
depends on ARCH_OMAP2PLUS
select DDR
help
This driver is for the EMIF module available in Texas Instruments
SoCs. EMIF is an SDRAM controller that, based on its revision,
supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
This driver takes care of only LPDDR2 memories presently. The
functions of the driver includes re-configuring AC timing
parameters and other settings during frequency, voltage and
temperature changes
config OMAP_GPMC
bool
select GPIOLIB
help
This driver is for the General Purpose Memory Controller (GPMC)
present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
interfacing to a variety of asynchronous as well as synchronous
memory drives like NOR, NAND, OneNAND, SRAM.
config OMAP_GPMC_DEBUG
bool "Enable GPMC debug output and skip reset of GPMC during init"
depends on OMAP_GPMC
help
Enables verbose debugging mostly to decode the bootloader provided
timings. To preserve the bootloader provided timings, the reset
of GPMC is skipped during init. Enable this during development to
configure devices connected to the GPMC bus.
NOTE: In addition to matching the register setup with the bootloader
you also need to match the GPMC FCLK frequency used by the
bootloader or else the GPMC timings won't be identical with the
bootloader timings.
config MVEBU_DEVBUS
bool "Marvell EBU Device Bus Controller"
default y
depends on PLAT_ORION && OF
help
This driver is for the Device Bus controller available in some
Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and
Armada 370 and Armada XP. This controller allows to handle flash
devices such as NOR, NAND, SRAM, and FPGA.
