Creating and applying a patch to uboot

[uBootUser]

Hi everyone,

I have done some changes to uboot for my board. I would like to create it as a patch, which can be applied easily.
Can somebody help me in learning how to create and apply a patch to uboot?
If any document is available for the same, pls share the link.

Thanks in advance.
