Yes, you are right. We need the config ARM_CCI even now, which enables 
the building of the arm-cci.c.

Stephen,

We need the following fix on the linux-next.

Oops, sorry about that.  I have fixed up the merge resolution for today
so that file starts like this:

#
# Bus Devices
#

menu "Bus devices"

config ARM_CCI
	bool

config ARM_CCI400_COMMON
	bool
	select ARM_CCI

config ARM_CCI400_PMU
	bool "ARM CCI400 PMU support"
	default y
	depends on ARM || ARM64
	depends on HW_PERF_EVENTS
	select ARM_CCI400_COMMON
	help
	  Support for PMU events monitoring on the ARM CCI cache coherent
	  interconnect.

	  If unsure, say Y

config ARM_CCI400_PORT_CTRL
	bool
	depends on ARM && OF && CPU_V7
	select ARM_CCI400_COMMON
	help
	  Low level power management driver for CCI400 cache coherent
	  interconnect for ARM platforms.

config ARM_CCN
	.
	.
	.
