I want to control the GPIO of LS1046A using Codewarrior.

[Johnson_s]

I am thinking of using Codewarrior to control the GPIO of LS1046A. I believe that it is possible to achieve this by using Hard Coded mode.

However, even when trying to create it based on Helloworld, I cannot find the GPIO driver and I don't know how to create it.

Please help me.

Do you mean you don't know how to develop GPIO driver for LS1046A platform?

Please refer to GPIO driver in u-boot.
