Thanks for the information.
Based on your input, I could successfully update the dts file and gpio
controller configuration. I verified from the GPIO chip intialized and added
properly. But, still Iam getting the message as
"No NAND device found!!!".
In our system we have two flash NOR connected thru GPCM and NAND device(STM
Flash is NAND512W3A2C) connected using UPM.
NAND Flash starting address: fb000000(64 MB size)
NOR Flash starting address: fa000000 (16 MB size)
MPC8321E processor's port C, PIN 15 connected to the R/B PIN of NAND Flash.
Below are the dts file changes in mpc832x_rdb.dts
DTS File changes:

Please let me know if I missed out anything.
