This may be a dumb question, but system would you want to run a pSeries
kernel without PCI on? Is this just for build tests, or is there an
actual application for this?

 procfs-$(CONFIG_PPC64)         :=3D proc_ppc64.o
 obj-$(CONFIG_PROC_FS)          +=3D $(procfs-y)
-rtaspci-$(CONFIG_PPC64)                :=3D rtas_pci.o
-obj-$(CONFIG_PPC_RTAS)         +=3D rtas.o rtas-rtc.o $(rtaspci-y)
+rtaspci-$(CONFIG_PPC64)-$(CONFIG_PCI)  :=3D rtas_pci.o
+obj-$(CONFIG_PPC_RTAS)         +=3D rtas.o rtas-rtc.o $(rtaspci-y-y)
 obj-$(CONFIG_RTAS_FLASH)       +=3D rtas_flash.o
 obj-$(CONFIG_RTAS_PROC)                +=3D rtas-proc.o

The double -y suffix always confuses me. Do you mind turning this
into a Kconfig symbol instead?

config RTAS_PCI
	default y
	depends on PCI && PPC64 && PPC_RTAS

obj-$(CONFIG_RTAS_PCI)	+=3D rtas_pci.o
