The i.MX23 / i.MX28 have a small amount of On-Chip RAM which is also necessary
for suspend to RAM and standby mode. But before we need to remove the fake reg
properties of all internal bus nodes as discussed in this thread [1].
This patch series requires Fabio Estevam's recent series "ARM: dts: imx23:
Remove skeleton.dtsi inclusion" [2].

Correct me if i'm wrong, but there is only one AHB bus and only the connected peripheral devices like ocram or USB controller have a memory mapped start address not the bus itself. > > diff --git a/arch/arm/boot/dts/imx28.dtsi b/arch/arm/boot/dts/imx28.dtsi > index 0ad893bf5f43..8e5718df06b2 100644 > --- a/arch/arm/boot/dts/imx28.dtsi > +++ b/arch/arm/boot/dts/imx28.dtsi > @@ -47,6 +47,19 @@ > }; > }; > > + ahb at 0 { > + compatible = "simple-bus"; > + #address-cells = <1>; > + #size-cells = <1>; > + reg = <0x0 0x80000000>; > + ranges; > + > + ocram: sram at 0 { > + compatible = "mmio-sram"; > + reg = <0x0 0x20000>; > + }; > + }; > + > apb at 80000000 { > compatible = "simple-bus"; > #address-cells = <1>; > ^ permalink raw reply [flat|nested] 11+ messages in thread
