[U-Boot] [PATCH 0/7] Remove defines for SPI default speed and mode

[U-Boot] [PATCH 0/7] Remove defines for SPI default speed and mode

[Patrick Delaunay]

This patch-set finish (after the last Simmon comment)
and depends on the previous serie named:
"Read default speed and mode values from DT"

http://patchwork.ozlabs.org/project/uboot/list/?series=76834

This patchset remove the unnecessary defines for SPI speed and mode
when DM mode is used for SPI (CONFIG_DM_SPI_FLASH).

Build result is available for the serie in gihub and travis:
https://github.com/patrickdelaunay/u-boot/tree/topic/spi
https://travis-ci.org/patrickdelaunay/u-boot/branches

[U-Boot] [PATCH 1/7] spi: update management of default speed and mode

[Patrick Delaunay]

The 2 default values for SPI mode and speed are
only if CONFIG_DM_SPI_FLASH is not defined
- CONFIG_SF_DEFAULT_SPEED
- CONFIG_SF_DEFAULT_MODE

Inverse the logic of the test to remove these two defines.

Patch only applies to cmd/sf.c, the other once do not apply (original patch was
too old).
Or am I missing something?

I have applied 
http://patchwork.ozlabs.org/project/uboot/list/?series=76834 before 
applying this series (as Patrick wrote in his cover letter) and it 
worked with current master.

Better define globally with in spi includes or some common include
instead of making ifdef changes all over.

Could you please change this patch and remove this unnecessary code?

Please try trim it for better, adding ifdef on top ifdef look, not
good. see my comment on 1/7

[U-Boot] [PATCH 7/7] spi: remove define for SPI default SPEED and MODE

[Patrick Delaunay]

In DM mode, the speed and mode defaults value will be taken from DT,
so these defines should be never used and can be removed.

After applying both of your patches, the da850evm no longer boots from
SPI flash.

U-Boot SPL 2019.01-rc1-00754-g21fb8c41b1 (Dec 10 2018 - 09:02:28 -0600)
Trying to boot from SPI
Warning: SPI speed fallback to 100 kHz

U-Boot SPL 2019.01-rc1-00754-g21fb8c41b1 (Dec 10 2018 - 09:02:28 -0600)
Trying to boot from SPI
Warning: SPI speed fallback to 100 kHz

I then tried to apply the first patch, and it also fails booting.

I'll reply to the original series with a similar message.  Looking at
the comments, it looks like the code is assuming the DM_SPI_FLASH
means DT when in reality, the da850evm's SPL is using platdata.  I
looked at the platdata structure and I didn't see entries for SPI mode
or speed.  However, I cannot prove this is the issue on the da850evm
without diving into it a bit more.

I just did test this and it worked for me. Booting from QSPI on 
socfpga_socrates and loading something in U-Boot via sf probe/sf read, so:

Adam, from reading the da850-emv.dts and its '-u-boot.dtsi', it seems 
the fdtgrep indicators to keep the flash for the SPL dts are missing 
(compare to socfpga_cyclone5_socrates-u-boot.dtsi). In this case, the 
code does not find a flash node.

The same would of course apply when using platdata.

Simon

I tried modifying the -u-boot.dtsi file to look like:

&flash {
     compatible = "m25p64", "spi-flash";
     u-boot,dm-pre-reloc;
};

Unfortunately, I not get some build errors.  Do you have any
suggestions?   I know the dtsi didn't need the "u-boot,dm-pre-reloc;"
before this patch.
 Might there be a platdata example I can follow?

The build errors as as follows:

That should be correct when using DTS. I have no idea about the platform 
data, sorry. That's a todo on my list to see if it gives me enough 
memory to enable FIT/signature support in my SPL, but I haven't got to 
compile it, yet, as cadence QSPI does not seem to support platdata, yet.

Well, that's only partly true. You need this information in SPL unless 
you go the hacky way of the define that Patrick wants to remove here. 
And the standard way to get this information into SPL is the devicetree.

I think Patrick did the right move to send this series so that we can 
drop the two defines and get the values from dts. Now platdata seems to 
be missing, so this must be solved.

As written above, I don't know of any. Even without build errors, I'm 
not sure it would work...

[U-Boot] [PATCH 0/7] Remove defines for SPI default speed and mode

Hi Patrick,

FYI this patchset breaks some machines:
https://travis-ci.org/pevik/u-boot/builds/466192406


Kind regards,
Petr

I might be wrong, but I think that build log indicates an error on a
line that should not exist any more after applying this series and the
one the OP says it's based on:
http://patchwork.ozlabs.org/project/uboot/list/?series=76834

Yes I think I was not enough clear comment

The new serie depends on  the previous serie named:
 "Read default speed and mode values from DT"

You need to apllys this patchset :
