The kerne source I used now is 2.6.23 with MPC8313-erdb pached. I
think I should port 2.6.28 gpio function back to 2.6.23. Is it a
common way to implement it in the kernel I used or I should port
MPC8313-erdb pached to 2.6.28 opposite?

Through sysfs. See 'Sysfs Interface for Userspac
Thanks, got it. BTW, how to trigger GPIO level in user space
application? I also found arch/powerpc/platforms/52xx/mpc52xx_gpio.c
is a good example. Any reply is appreciate.

Hi All:
Is there a alreday written GPIO dirver or example for
MPC8313/similar ppc platform. It looks like many people need GPIO
dirver to control LED, etc... I think is it possible to write a
general gpio driver for all ppc platform and only need to modify gpio
iomap information of dtb file. Ple
