From 4c75a6f441cdd1c69a6c173bc7944e12c2ba6f84 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sat, 11 Nov 2006 17:24:53 +1100 Subject: [POWERPC] Generic DCR infrastructure This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that can be used by drivers to transparently address either native DCRs or memory mapped DCRs. The implementation for memory mapped DCRs is done after the binding being currently worked on for SLOF and the Axon chipset. This patch enables it for the cell native platform Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras --- arch/powerpc/Kconfig | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'arch/powerpc/Kconfig') diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index 96316c86610..0e564d30fc4 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -160,9 +160,11 @@ config PPC_86xx config 40x bool "AMCC 40x" + select PPC_DCR_NATIVE config 44x bool "AMCC 44x" + select PPC_DCR_NATIVE config 8xx bool "Freescale 8xx" @@ -208,6 +210,19 @@ config PPC_FPU bool default y if PPC64 +config PPC_DCR_NATIVE + bool + default n + +config PPC_DCR_MMIO + bool + default n + +config PPC_DCR + bool + depends on PPC_DCR_NATIVE || PPC_DCR_MMIO + default y + config BOOKE bool depends on E200 || E500 @@ -453,6 +468,7 @@ config PPC_CELL config PPC_CELL_NATIVE bool select PPC_CELL + select PPC_DCR_MMIO default n config PPC_IBM_CELL_BLADE -- cgit v1.2.3
