Hello Ben,
Thank you for your advice and I've read through the README file in the top directory and the Manual on the wiki site. Both of them emphasize the configuration for different platforms, with less on how to port it. Here I've found that in the 7th chapter of <Embedded Linux Primer> the function and basic concept of bootloader is clearly explained. I hope that it will help those guys like me.
I've tried to find the most similar board to our platform, but I don't know where can find more information on the boards list in the /configs directory. Google gives too many useless results, which always give just some words on it, yet not details.
Thank you for your help.
BEST REGRADS AND HAVE A NICE DAY

Porting U-boot is not a trivial task, but neither is it impossible. The one thing that I can't stress strongly enough is that you need to be very familiar with the hardware on your board. You need to know what every chip does and understand its interfaces. If you feel you have the necessary skills and are willing to make the investment in really learning this stuff, you will find no shortage of help on this list.
Very few people take on the task of building a board core from scratch. Most were originally based on some kind of reference design, and many of those reference designs are supported in U-boot. Every board has a CPU, RAM and some kind of non-volatile storage, usually parallel NOR flash. Most have networking capabilities. If you can identify these parts, you can hopefully find a good starting point. If you're stuck, send an e-mail listing these parts and somebody may be able to point you in the right direction.
regards, Ben
