I have a few queries about handling static memory controller (SMC) of ATMEL
1. How is SMC configured when DT is used ?
2. With "d6a0166 atmel/nand: add DT support", ek_add_device_nand() is no more
present (which was earlier configuring SMC), so is SMC configuration handled
by Kernel on DT boot or is it done by bootloader when DT ?
3. How ek_add_device_dm9000() is going to be achieved with DT ?
4. Is there any plan to create a driver out of SMC code & use DT with it ?
Reason for bringing these queries is that TI OMAP chips have GPMC [1], SMC in ATMEL
seems somewhat similar and currently GPMC is configured in platform code, &
we are creating a driver out of that code [2]. There are different views on where
GPMC driver should go, mfd, misc folders etc, but could not yet get concrete
suggestions even with a loud cry.
If ATMEL is also going driver way, then probably our voice together may be
heard and hopefully it will expedite the matter.

GPMC (General Purpose Memory Controller) in brief:
GPMC is an unified memory controller dedicated to interfacing external
memory devices like
Asynchronous SRAM like memories and application specific integrated circuit devices.
Asynchronous, synchronous, and page mode burst NOR flash devices NAND flash
Pseudo-SRAM devices
GPMC has to be configured as required by timings of the connected
peripheral. It needs to be configured only initially. Once it is
configured it can be used to handle different protocols like NAND,
NOR. Various kinds of devices like ethernet, uart, usb, fpga etc
can work using GPMC interface. GPMC has a seperate additional
functionality of NAND handling

I'm going to add it too my idea was to create something similiar as the
pintrl
you register the ddifferent bank supported buy the SoC and then the driver
request the bank for the dev_name
at soc level you will set the default timings and then the drvier may
manipulate them
I already update the API of sam9_smc to abstract the access to the register.
I expect the code for the request to be generic but handling of the timing IP
specific
Evenif the GPMC is smiliar as the SMC I do not expect a generic API to manage
it easly (for the timings).
Best Regrds,

Is SMC code being converted to driver ?
