Any patch for MTD_FSL_UPM_NAND with OF_GPIO

Hi
I am using linux-2.6.26.8 kernel. In drivers/mtd/nand/Kconfig,
MTD_NAND_FSL_UPM depends on MTD_NAND && OF_GPIO && (PPC_83xx || PPC_85xx).
But I didnt find any way to select OF_GPIO option in "make menuconfig". So I
removed it from Kconfig file and got MTD_NAND_FSL_UPM in menuconfig. I
selected it and did "make uImage". This is giving few errors:

include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep':
include/asm-generic/gpio.h:135: error: implicit declaration of function
'gpio_get_value'

make[2]: *** [drivers/mtd/nand] Error 2

I am suspection that some gpio lib is missing. So any patch is there to this
problem??
