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' include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep': include/asm-generic/gpio.h:141: error: implicit declaration of function 'gpio_set_value' In file included from drivers/mtd/nand/fsl_upm.c:21: include/linux/of_gpio.h: At top level: include/linux/of_gpio.h:26: error: field 'gc' has incomplete type include/linux/of_gpio.h: In function 'to_of_gpio_chip': include/linux/of_gpio.h:34: warning: type defaults to 'int' in declaration of '__mptr' include/linux/of_gpio.h:34: warning: initialization from incompatible pointer type drivers/mtd/nand/fsl_upm.c: In function 'fun_probe': drivers/mtd/nand/fsl_upm.c:203: error: implicit declaration of function 'gpio_request' drivers/mtd/nand/fsl_upm.c:208: error: implicit declaration of function 'gpio_direction_input' drivers/mtd/nand/fsl_upm.c:242: error: implicit declaration of function 'gpio_free' make[3]: *** [drivers/mtd/nand/fsl_upm.o] Error 1 make[2]: *** [drivers/mtd/nand] Error 2 make[1]: *** [drivers/mtd] Error 2 make: *** [drivers] Error 2 I am suspection that some gpio lib is missing. So any patch is there to this problem?? Regards Koteswar
