Hi
After run the following commands
make distclean
make allmodconfig ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu-
make oldconfig ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu-
make -j64 ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu-
I get some warning:
arch/powerpc/boot/dts/mpc5200b.dtsi:267.20-280.4: Warning (pci_bridge):

..
For the problem about "node name for SPI buses should be 'spi'":
Rename the psc@2000 to spi@2000 in arch/powerpc/boot/dts/o2d.dtsi can
fix it.

For the problem about "missing ranges for PCI bridge (or not a bridge)":
Ranges should be add in arch/powerpc/boot/dts/mpc5200b.dtsi.

I think the ranges should be add by someone who knows the mpc5200 better.
Can anyone fix this?
