You can use "ls" to list all GPIO devices, and you should also see GPIO ports in
above table.
Example of testing GPIO
Set gpio2 GPI(in)
# echo in > ./gpio2/direction
# cat ./gpio2/direction
in
Set gpio12 GPO (out)
# echo out > ./gpio12/direction
# cat ./gpio12/direction
out
Set gpio12 GPO value "1"
# echo 1 > ./gpio12/value
