Hello,
Linux and Uboot can be customized via patches that are applied with bbappend-files.
To customize the kernel, create a recipes-kernel/linux/linux-fus.bbappend
To customize the u-boot create a recipes-bsp/u-boot/u-boot-fus.bbappend
In these append files, you only have to add the directory with your patches to the source path and the names of the patches.

Thanks for your response, but the question was what is the best strategy for modify u-boot to configure the imx6 IOMUX settings.
Do I have to modify board/F+S/fsimx6ul/fsimx6ul.c file?
Yes, this is a good place to do this.
Do I have to copy board/F+S/fsimx6ul directory in other specific board directory with my own config items?
No, this is not necessary. Just change our file. Then if we ever change something again, you'll automatically get the new changes when merging your code with our new code. If you have an extra file, you always have to take care to apply any changes that we did in our file to your extra file.
How do I modify the default u-boot configuration?
Some settings are modified via make menuconfig, some settings are directly given in include/configs/fsimx6.h.
