I don't see the need for PS3GELIC_UDBG, without PPC_EARLY_DEBUG_PS3GELIC it just causes gelic_udbg.c to be built, but never called. The diff below fixes the error AFAICS. I can just fold it in if you're happy with that Arnd. diff --git a/arch/powerpc/Kconfig.debug b/arch/powerpc/Kconfig.debug index ea4033abc07d..8c80b154e814 100644 --- a/arch/powerpc/Kconfig.debug +++ b/arch/powerpc/Kconfig.debug @@ -271,7 +271,6 @@ config PPC_EARLY_DEBUG_USBGECKO config PPC_EARLY_DEBUG_PS3GELIC bool "Early debugging through the PS3 Ethernet port" depends on PPC_PS3 - select PS3GELIC_UDBG help Select this to enable early debugging for the PlayStation3 via UDP broadcasts sent out through the Ethernet port. diff --git a/arch/powerpc/platforms/ps3/Kconfig b/arch/powerpc/platforms/ps3/Kconfig index a44869e5ea70..e9c1087dd42e 100644 --- a/arch/powerpc/platforms/ps3/Kconfig +++ b/arch/powerpc/platforms/ps3/Kconfig @@ -167,16 +167,4 @@ config PS3_LPM profiling support of the Cell processor with programs like perfmon2, then say Y or M, otherwise say N. -config PS3GELIC_UDBG - bool "PS3 udbg output via UDP broadcasts on Ethernet" - depends on PPC_PS3 - help - Enables udbg early debugging output by sending broadcast UDP - via the Ethernet port (UDP port number 18194). - - This driver uses a trivial implementation and is independent - from the main PS3 gelic network driver. - - If in doubt, say N here. - endmenu diff --git a/arch/powerpc/platforms/ps3/Makefile b/arch/powerpc/platforms/ps3/Makefile index 86bf2967a8d4..bc79bb124d1e 100644 --- a/arch/powerpc/platforms/ps3/Makefile +++ b/arch/powerpc/platforms/ps3/Makefile @@ -3,7 +3,7 @@ obj-y += setup.o mm.o time.o hvcall.o htab.o repository.o obj-y += interrupt.o exports.o os-area.o obj-y += system-bus.o -obj-$(CONFIG_PS3GELIC_UDBG) += gelic_udbg.o +obj-$(CONFIG_PPC_EARLY_DEBUG_PS3GELIC) += gelic_udbg.o obj-$(CONFIG_SMP) += smp.o obj-$(CONFIG_SPU_BASE) += spu.o obj-y += device-init.o cheers
