Hi,
I'm running P2020 in AMP mode, each core running its linux os.
Ethernet 1(@25000) and Ethernet 2(@26000) assigned to Core0 are working
fine.
I'm facing problems with Ethernet interface(@24000) assigned to Core1, its
not working.
I'm using dts file which were added by :
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-September/075594.html
Looks either there is some mistake in the dts file or my understanding is
wrong.
MDIO @24000 is defined in core0 dts file though the Ethernet is assigned to
Core 1.
DTS files :

http://web.mornfall.net/repos/linux-2.6/git/arch/powerpc/boot/dts/p2020rdb_camp_core1.dts
mdio at 24520 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,gianfar-mdio";
reg = <0x24520 0x20>;
phy0: ethernet-phy at 0 {
interrupt-parent = <&mpic>;
interrupts = <3 1>;
reg = <0x0>;
};
phy1: ethernet-phy at 1 {
interrupt-parent = <&mpic>;
interrupts = <3 1>;
reg = <0x1>;
};
};
Also, MDIO for 25520 has wrong register value:
mdio at 25520 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,gianfar-tbi";
reg = <0x26520 0x20>;
tbi0: tbi-phy at 11 {
reg = <0x11>;
device_type = "tbi-phy";
};
};
Please correct me if I'm wrong. Has freescale released a working dts files
for P2020 in AMP mode ? as this seems to be not working.
Best Regards
Prasanna Khanapur.
