[U-Boot] [PATCH v5 2/5] dm: spi: Convert Freescale ESPI driver to driver model

[Xiaowei Bao]

From: Chuanhua Han <chuanhua.han@nxp.com>

Modify the Freescale ESPI driver to support the driver model.
Also resolved the following problems:

===================== WARNING ======================
This board does not use CONFIG_DM_SPI. Please update
the board before v2019.04 for no dm conversion
and v2019.07 for partially dm converted drivers.
Failure to update can lead to driver/board removal
See doc/driver-model/MIGRATION.txt for more info.
====================================================
===================== WARNING ======================
This board does not use CONFIG_DM_SPI_FLASH. Please update
the board to use CONFIG_SPI_FLASH before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================

Changes in v5:
	- Modify the function spi_cs_activate to fsl_spi_cs_activate.
	- Move cs to the parameter of the fsl_spi_cs_activate function.
Changes in v4:
	- Update copyright information.
	- Move the fsl_espi_platdata data structure to the 
include/dm/platform_data/.
	- Merge the contents of the fsl_espi_priv structure into 
the fsl_spi_slave structure.
	- Implement the fsl_espi_set_speed function.
	- Implement the fsl_espi_set_mode function.
	- Implement the espi_release_bus function.
	- Remove unwanted fsl_espi_bind functions.
	- Implement the fsl_espi_child_pre_probe function as needed.
	- Use #if CONFIG_IS_ENABLED(OF_CONTROL) && !CONFIG_IS_ENABLED(OF_PLATDATA).
Changes in v3:
	- Add a cover-letter for this patch set.
Changes in v2: 
	- The fsl_espi driver support both OF_CONTROL and PLATDATA.

[Lukasz Majewski]

Hi Xiaowei,

> From: Chuanhua Han <chuanhua.han@nxp.com>

> non-DM SPL.

I've posted recently a set of patches to move setting of DM_SPI_FLASH
to Kconfig:
https://patchwork.ozlabs.org/cover/1146494/

Please rebase your work on top of it.

Did this set of patches merge to the u-boot mainline? Do I need to depend on your patches?
If yes, please provide the full patches link, I can't see the contents of this set of patches.

When you open the link:
https://patchwork.ozlabs.org/cover/1146494/

On top left you have: 
"Related" -> "show"

After clicking on it you will see the list of patches.

You may also want to use "Series" on top right and download the whole
patch series.

These are not the only problems with this driver it is borken for anything
but loading small amount of data from SPI NOR flash.
Look at spi_xfer:
  overuse of malloc/memcpy
  misuse of word size(always 32 bits) making proper of ESPI_EV_RNE/ESPI_EV_TNF impossible.
  random test of 0x0b: 
  		memcpy(data_in, buffer + 2 * cmd_len, tran_len);
		if (*buffer == 0x0b) {
			data_in += tran_len;
			data_len -= tran_len;
			*(int *)buffer += tran_len;
		}

I think fixing the driver to work properly first is preferable to DM conversion.

Thanks a lot for your comments, in fact, these code exist all the time, I never modify 
this part code, and I have verified the SPI flash use 4K data, the test result is ok,
I will check and analyze this part code, and give the reply later, thanks.

Yes, this code has been borken for years and like I said, it only works for SPI NOR flash which is what you tested.
Try a simple SPI device, reading and writing registers.

Here is an old hack for loading FPGAs using ESPI_COM_TO, hopefully this can be of some use:
https://patchwork.ozlabs.org/patch/330242/

In short, the inner working of spi_xfer() needs a full rewrite, using the proper SPI word size, you have no chance
of supporting SPI_LSB_FIRST without correct word size.

Thanks a lot, I think I need to do another new patch which reimplement the xfer function,
This is better, because this issue fix should not in DM patch, I will submit another new patch to fix
this issue, but maybe spend some time, because I am not very clear about the FSL ESPI
driver, and the verification will be a problem, because I don't find other SPI device except
SPI flash device in our RDB or QDS board, but I am going to do this.

Thanks, I think random access(read/write) to SPI NOR flash will be enough for testing.
It won't be any worse than today as it is broken already.

Hi Lukasz, thanks for your comments, ask a question, I modify my driver like this:
diff --git a/drivers/spi/fsl_espi.c b/drivers/spi/fsl_espi.c
index fd5ac97..54be036 100644

 }

 #ifndef CONFIG_DM_SPI

When I compile the driver with SPL mode, the DM or non DM mode cod will be compiled
together, I think CONFIG_IS_ENABLED(DM_SPI) is 0 or 1, so the DM code or non DM code
will be compiled, but not both, this make me confused, do I miss something, could you tell
me the reason? Thanks a lot.

So the CONFIG_IS_ENABLED(FOO) is true if:

1. The CONFIG_FOO is defined in Kconfig files (if it is defined in
./include/configs/<board.h> then CONFIG_IS_ENABLED will return false,
which is wrong).

2. The CONFIG_IS_ENABLED(FOO) is true if in Kconfig you have defined
CONFIG_FOO

3. CONFIG_IS_ENABLED(FOO) is true if in Kconfig you have defined
CONFIG_SPL_FOO

So the CONFIG_IS_ENABLED(FOO) shall be used in conjunction with
CONFIG_DM_FOO (SPI in your case).

[U-Boot] [PATCH v5 1/5] spl: dm: disable SPI DM flash for non-DM SPL

[Lukasz Majewski]

Hi Xiaowei,

> Hi Lukasz,
>

There was some discussion regarding this work with Frieder (CC'ed),
who has prepared similar patch set.

Some portions of this series:
spi: Split CONFIG_DM_SPI* to  CONFIG_{SPL_TPL}DM_SPI*

has been applied.

However, I don't know if Frieder is going (or already has) to prepare
new version of this patch set.

I have sent one part of the necessary changes: [1].
The latest version of the whole conversion can be found here: [2].
I need to test these changes with buildman before I send the remaining 
parts. I hope I will find some time to do this in the next days.

Frieder

Hi Frieder,

Do you complete the test of changes, I have some patches depend on your patches,
Thanks a lot.

Sorry, the CONFIG_SPI_FLASH_MTD is merged, but the other remaining 
patches for CONFIG_DM_SPI_FLASH, etc. are not.
The last time I tried to get them ready I once again got caught in an 
endless loop of fixing Kconfig issues and testing.

If you need some of the fixes, you could try adding them to your own 
patchset and test and resend them.

Regards,
Frieder
