The GPMC is a unified memory controller dedicated for interfacing with external memory devices like - Asynchronous SRAM-like memories and ASICs - Asynchronous, synchronous, and page mode burst NOR flash - NAND flash - Pseudo-SRAM devices This driver will take care of setting up the GPMC based on the settings specified in the Device tree and then probe its children.

Enable driver model for Memory Controller devices.
|
|
These devices provide Memory bus interface to various devices like
|
|
SRAM, Ethernet adapters, FPGAs, etc.
|
|
For now this uclass has no methods yet.

help
|
|
This is a driver model based Memory Controller driver for sandbox.
|
|
Currently it is a stub only, as there are no usable uclass methods
|
|
yet.

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.
