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

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:

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

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:

Trying to boot from SPI

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.

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
