Current sdram driver is only applied to gen5 device, hence it is better
to rename sdram driver to more specific name which is related to gen5
device.

From: Tien Fong Chee <tien.fong.chee@intel.com>

Add function for both multiple DRAM bank and single DRAM bank size
initialization. This common functionality could be used by every single
SOCFPGA board.

This is required by DDR to configure NoC firewall setting based on DTS.
The NoC firewall is used to control any data transaction between IP
interfacing with DDR.

+Arria 10 FPGA design filename and partition properties
+------------------------------------------------------
+In Intel Arria 10 SoCFPGA, FPGA is programmed by both SPL and U-boot.
+Those FPGA designs are normally stored in the flashes, it could be in SDMMC,
+QSPI and NAND.
+For bootloader to know where to look those files and how to program the FPGA,
+those files' filename, and flash partition are defined in device tree.
+There are three properties as shown in below:
+
+Example
+-------
+/ {
+	chosen {
+		cff-file = "ghrd_10as066n2.periph.rbf.mkimage";
+	};
+};
+
+cff-file is assigned with peripheral raw binary filename. Peripheral raw binary
+file is used to configure FPGA IOs, IO48, DDR and PLL.
+
+/ {
+	chosen {
+		cffcore-file = "ghrd_10as066n2.core.rbf.mkimage";
+	};
+};
+
+cffcore-file is assigned with core raw binary filename. Core raw binary
+file contains FPGA design, which is used to configure FPGA CRAM and ERAM.
+
+/ {
+	chosen {
+		cff_devpart = "0:1";
+	};
+};
+
+cff_devpart is assigned to partition(default: FAT) where cff-file and
+cffcore-file are stored.
+[<dev{:part}>] dev is flash device number and part is flash partition.
+
+Note: For cff-file, the device number is always zero, and only the partition
+could be defined by user.

During FPGA program, FPGA raw binary data file would be searched from
flash based on the file name defined in DTS, and then feeding the FPGA
file found from flash into FPGA manager for configuring FPGA.

You should enable stuff only after you add the necessary support bits ...

This should be a property of the FPGA , not the system . You can have
multiple FPGAs and then this would become a problem.

How can a generic FPGA driver depend on random FS functionality ?
This is broken ...

128 MiB malloc area is nonsense, even those 64 MiB are iffy. Why would
you ever need that in a bootloader ?

But you enabled support for this in patch 1/19 ... ordering issue ?
Patch changelog doesn't match what the patch does ...

Why is this not a generic code ? Load stuff from FS and program it into
the FPGA directly, should be pretty generic operation IMO.

What does that mean ? Expand the description, it's inobvious

This should work on al boards, so why do you need this macro ?
Also, this should go into arch/arm/ , not board/

I enabled it as early as possible, because i would like to use
compiling for detecting any code errors while adding the neccesssary
support bits. I can rearrange the patches sequence.

This setting is for the only one FPGA inside our SoCFPGA. For external
multiple FPGAs programming, user is adviced to store the FPGA filename
in environment variable and programming FPGA with fpga loadfs command.

Please note that, peripheral rbf and partition are required in SPL to
set up DDR before booting to U-boot.

random FS? There would having FAT FS for SDMMC, and UBI FS for QSPI and
NAND(implement later). May be i can replace #ifdef CONFIG_FS_FAT witht
the codes below, what do you think?

This is min require to malloc the buffer in SDRAM for core rbf. Less
than this value, something would going wrong, i'm not recall what issue
because i already tested this quite long time ago, problem related to
FAT and malloc.

This patch is adding the FPGA loadfs command support for Arria 10.
I enabled FPGA loadfs in patch 1/19, so i can compile the changes in
this patch immediately.

So, you want me to improve the commit message and reordering?

This is generic multiplexing code, calling generic function name

You just said it yourself, it is for the only FPGA in your SOCFPGA ,
thus it is a property of the FPGA , not a chosen .

Driver should not depend on specific FS.

Why do you pass around the struct flashinfo then ?

Isn't the loadfs supposed to read the data from the FS and program them
into the FPGA without having to read the whole bitstream into the RAM ?

And you fix it how ... ?

That should be in the commit message, describe the problem and how you
fix it.

Every socfpga platform in u-boot has a dts, so you can always extract
the memory config from it and it's the preferred method.

Okay, what i trying to tell is that there is no multiple FPGAs in our
SOCFPGA. The filename is not any hardware properties, it is just a info
to tell SPL and U-boot which file to look for programming FPGA.
According to chosen node document, chosen node doesn't represent a real
HW, but serves as place for passing data. This is why our BSP tool put
the filename info here, the file is named by user in our tool, and this
info would be consumed by SPL to program FPGA.

I afraid to use fs_read, need to enable more FS features, which would
take a lot memory, could be run out of it in SPL. Do you think it is
good to try in SPL?

The operation is either reading data from FS into memory and program
into FPGA chunk by chunk if memory is smaller than data.
or
Reading whole data from FS into memory and program whole into FPGA if
memory is larger than data.

What would happen if you attached an FPGA over ie. SPI or PCIe ?
Then you have two FPGAs in the system and you need to describe them in
the DT and your "chosen" approach breaks down.

Your BSP tool is broken.

Don't you have like 256k for the SPL on Gen10 ?

We want to support only the DT method, so drop the other one.

We only need to decribe the internal FPGA of SoCFPGA in DT such as
"chosen" to specify which file should SPL looking for getting SDRAM up
with programming correct periph rbf into FPGA. When the SDRAM is up
running, then only SPL can load U-boot and booting from there.
The rest of external multiple FPGAs can be configured through U-boot,
such as boot script, interactive in console or from PC host. Other than
that, external FPGA can also be configured through Linux.

The BSP tool is used to describe internal FPGA in SOCFPGA. Other
external FPGAs other than SOCFPGA itself, it can be programmed through
U-boot.

Yes, i afraid it wouldn't be enough when we enable all NAND and QSPI
flashes feature. Our stretch goal is to have all flashes with one

This is incorrect. You describe the hardware in DT, if you have multiple
FPGAs, then your approach breaks down.

The BSP tool is broken if it generates broken DT, do I have to repeat
myself ?

Let me clarify, we don't have FPGA HW properties described in DT, only
the RBF files are defined under chosen node. The files are defined only
apply for FPGA inside SOCFPGA.
Multiple external FPGA are configured through U-boot.

BSP tool is only generate the RBF filename for FPGA inside SOCFPGA.

I assume you are saying FPGA connected to EPCQ, and this is one of the
external FPGA configuration, like PCIE. For any external FPGA
configuration, FPGA itself/external HOST would get the FPGA data from
storage such as EPCQ and configuring the FPGA without HPS/Bootloader
intervine. SPL/U-boot would skip the FPGA configuration process when
they see the mode is set to external FPGA configuration.

I know you want a DT to describe all FPGAs with FPGA node and their own
data filename in every node. But, at this moment, all external FPGAs
chip other than SOCFPGA itself are configured through U-boot(script &
env variable), or external FPGA configuration method.

How about i just create a FPGA node for SOCFPGA, with FPGA data
filename within the node?

No, I mean FPGA connected over SPI bus.

I want DT which describes hardware and is not misdesigned crap.
Just because the BSP tool is broken does not mean I can allow upstream
to accept that, no way.

Isn't that what the FPGA manager in mainline Linux does already ?

Yeah, i will port from Linux DTS, and filenames added into the node.
