Ping does not work on my MPC8544 board, using linux2.6.23

Hi,all:
This is my first time to post on this maillist,I got a problem that ping can
not work and I am wondering if it is because of my mismatch of linux kernel
and DTC compiler version.
I am using mpc8544ds_bsp provided by freescale.
I used uboot2009.08 to boot my board successfully.
At first, I using the dtc compiler in this bsp which is version 1.1.0 along
with linux2.6.23 which is also provided by this bsp.
But I failded to boot the linux kernel.
And later, I tried out using dtc1.2.0 and the mpc8544ds.dts in linux-2.6.23,
there are some systax errors like hex to dec. And I modified the
mpc8544ds.dts to to fit dtc1.2.0.
And I boot linux successfully, but PING doesnot work now.
I am sure I set the ipaddr netmask ,and  default gateway correctly.
Does dtc1.2.0 can compile dts files under linux2.6.23?
Another question is that I found linux2.6.31 does not support
board mpc8544ds, And I never boot linux-2.6.31 on my board, why linux-2.6.31
doesnot provide a config file like mpc8544_ds_defconfig?
Thanks!

Probably not -- 2.6.23 is very old, and I think newer dtcs only support the
newer dts syntax.

It should.  What problems do you see?

Does mpc85xx_defconfig not work?

Yes mcp85xx_defconfig does not work, I can see mpc8540ads in the menuconfig,
but no mpc8544ds. And when I down load the generated uImage, It does not
work.

PING works now, after modifying the code of gianfar-mii.c

Try to change "link_address=3D'0x400000'" tp "link_address=3D'0x800000'"
in arch/powerpc/boot/wrapper.
If you have result, remember to give me a feedback.

Are you using the mpc8544ds device tree from 2.6.31, unchanged?  Try 
turning on CONFIG_PPC_EARLY_DEBUG.

No need to deselect the others, BTW.

mpc8544ds is supported by CONFIG_MPC85xx_DS.

I'm looking right at it, in arch/powerpc/platforms/85xx/Kconfig in 2.6.31.

mpc85xx_defconfig selects this option.
