If the use of MTD is restricted to passive serial, this is OK with me.
Yeah, but that is not how upstream things work. You need to also think
of any other use cases.
These are the things I want to achieve.
* transfer data using the SPI driver and not use board files.
For that, the FPGA

Sorry, I didn't follow this too closely. Do you have some pointers?

Hi Guys,
We are currently discussing how to support passive serial configuration
of FPGAs in u-boot.
Checking the u-boot source code reveals that only your boards
actually supports this.
