Wrong pin name, GPG3?

In case of this, how about to use one loop like this.
for (gpio = GPG3(0); gpio <= GPG3(7); gpio++)
s3c_gpio_cfgpin(gpio, S3C_GPIO_SFN(2));
since all pins use special function 2.
or others methods are welcome.
To Ben,
When do you apply previous gpio helper functions?
Thank you,
