Since CONFIG_IS_ENABLED(DM_SPI) is not working in SPL because
CONFIG_SPL_DM_SPI is not defined we should go with #ifdef CONFIG_DM_SPI.

Better enabled it for SPL, did you find any size constraint? if yet
try for platdata?

Hi Jagan,
it's not about any size constraint.
To my understanding the macro CONFIG_IS_ENABLED(DM_SPI) is true if
CONFIG_SPL_DM_SPI is defined during SPL build. Please tell me if I am
wrong.
At the moment this configuration parameter doesn't exist, so I used a
#ifdef
which works with CONFIG_DM_SPI.
Would you prefer to add CONFIG_SPL_DM_SPI as configuration parameter?
Bernhard

Hi Jagan,
Are there any news?

I think your board config is disabling DM_SPI and DM_GPIO for SPL
builds, enable it for SPL as well and try.
