The real thing here is not Yocto specific as you have to prepare the patches to Kernel and U-Boot.
Once you have those done, you should make a customer/project specific layer and add a board for you. After that add overridies to Kernel and U-Boot applying your patches so it is maintainable in future releases.

I think this gives you an idea.

Can anybody help me ? :
from the Development user's guide it seems that I need to use IOMUX to change the i.MX53 QSB to have additional UART on the board (p169). Did I get it cleary or I can use any UART (not app one for sure) right away form the J13 ?

In this case I think you'll really need to plug it in J13. But I think you'll also need to change the board file to enable it.
Ok, I assume that this "board file" is about the I/O definition. Thanks.
Nevertheless, I'm really surprised that from all the 5 UARTs not anyone can be accessed easier.
