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.

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.

|
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

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.

depends on (SOC_AM33XX || SOC_AM43XX) && SRAM
|
help
|
This driver is for the EMIF module available on Texas Instruments
|
AM33XX and AM43XX SoCs and is required for PM. Certain parts of
|
the EMIF PM code must run from on-chip SRAM late in the suspend
|
sequence so this driver provides several relocatable PM functions
|
for the SoC PM code to use.

Armada 370 and Armada XP. This controller allows to handle flash
|
devices such as NOR, NAND, SRAM, and FPGA.

physical addresses that mapped by no local access window
|
(LAW) or an invalid LAW, as well as bad cache state that
|
represents a coherency violation.
