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.

Dear Fabio,
I manually set spl_boot_list[] array with SPI, eMMCx, USB RAM etc. For SPI NOR flash loader = spl_ll_find_loader(spl_boot_list[i]) function (in spl.c) is returning a negative loader->boot_device number -442503140
May be there is a definition in u-boot/SPL config files to make file to generate SPI NOR flash boot code, instead of MMC, Which enable this SPL function to return positive correct value for SPI NOR Flash?
eMMC is working, but I did not put SPL and u-boot in eMMC; May be you can give me a link explaining how to SPL+u-boot.img to eMMC flash commands.
You can check board/warp7/README
I added puts() messages to trace the execution;
These are the messages at terminal.
U-Boot SPL 2018.05-rc1 (Apr 17 2018 - 22:43:50 -0700) SPL set_bd() SPL DRAM initialized SPL Malloc; gd flags board boot order spl boot list spl_boot_list:8 spl_boot_list:8 Trying to boot from -442503140
You need to debug why you are getting this.
Make sure your board is correctly configured to boot from SPI NOR via GPIO/fuses.
