the uart232 output as following:

Finalizing device tree... flat tree at 0x86e300
I do not know why?
I did not use OCM,only use DDR.

It looks like your device tree is probably bad. You should compare it to the arch/powerpc/boot/dts/virtex405*.dts file in the kernel tree that we provide.
We support the ML405 board which is the same board with a smaller FPGA on it.
You should build a system that is similar to that system, but a subset is probably fine. I would build a minimal system to get it up and running, like the UART and interrupt controller without the other peripherals.
