To bring up the board you need to load u-boot prior to Linux.
I mean that boot ROM code of the processor loads u-boot from some media and then u-boot loads Linux kernel.
If you are using some stadnard boadd you can use u-boot from its binary demo files.
For example here you can get u-boot-imx6ulevk_sd.imx file for i.MX6UltraLite Evaluation Kit board:

When the board is running u-boot you can see some diagnostic output in terminal.
And finally you can load Linux kernel using u-boot.

Have a great day,
Victor
