[U-Boot] u-boot 2018 SPI SPL

[Mehmet Ali İPİN]

Dear Fabio

Thank you very much for your directives and helps. 

I applied the steps in WARP board readme file, for the command 

=> ums 0 mmc 2

I received Unknown command 'ums' - try 'help'

I compared with  WARP7 defconfig and mx6sabresd_defconfig files added some definitions in WARP, but got error messages in make file.
Therefore I would appreciate your helps/commends if you write me the definitions in config/defconfig files to enable u-boot to run this command?

Best regads.

You can check board/warp7/README

You need to debug why you are getting this.

Make sure your board is correctly configured to boot from SPI NOR via GPIO/fuses.
