I'm sorry, the wording of my question was too short.
I have already fulfilled the steps described in the article.
But the article describes loading of the image from manufacturer - it is not
my case.
1. I create a configuration for my board from maxbcm config.
2. Set `BOOT_FROM` parameter in board\my\kwbimage.cfg to `uart`.
3. Set DDR timings/settings.
4. Upload and execute image via uart.
5. Memory training ended successfully.

But then I get the following messages in the terminal:
|  >>spl:board_init_r()
|  boot device - 8
|  ...
|  SPI probe failed.

Boot device 8 - constant `BOOT_DEVICE_SPI`.
Function code returns this value looks like:
|  u32 spl_boot_device(void)
|  {
|   /* Right now only booting via SPI NOR flash is supported */
|   return BOOT_DEVICE_SPI;
|  }

And now I repeat my question:
>Is it possible to load and boot Marvell Armada XP u-boot completely from
uart without spi or nand flash?
