Majunath Goudar - Oct. 8, 2013, 10:34 a.m.
This patch adds a OF dependency to configure the ARM_CCI in drivers/bus/Kconfig.
Without this patch, build system can lead to build failure. This was observed
during randconfig testing, in which ARM_CCI was enabled w/o OF being enabled.
Following was the error:

CC      drivers/bus/arm-cci.o
drivers/bus/arm-cci.c: In function ‘cci_ace_init_ports’:
drivers/bus/arm-cci.c:131:2: error: implicit declaration of function
‘of_find_node_by_path’ [-Werror=implicit-function-declaration]
  cpus = of_find_node_by_path("/cpus");
drivers/bus/arm-cci.c:131:7: warning: assignment makes pointer from integer
without a cast [enabled by default]
  cpus = of_find_node_by_path("/cpus");
cc1: some warnings being treated as errors
make[2]: *** [drivers/bus/arm-cci.o] Error 1
make[1]: *** [drivers/bus] Error 2
