Ok. Tha main problem is that if I cross-compile kernel for ARCH=ppc everythings work fine.

What should I do for this?!?!? * I've configured the port_config in lite5200_setup_cpu(void) function [arch/powerpc/platforms/52xx/lite5200.c]. I put in port_config the same value that I put with ARCH=ppc! However I'm sure that my u-boot sets-up the port_config register because fatls usb 0:1 / show me the content of usb-storage.

No. Configuring the Ethernet pins for USB IO is just a pin routing board setup task. You do need to make sure U-Boot sets up the port_config register correctly, but it doesn't impact the device tree. You don't need to change any of the values in the USB node. However, if the Ethernet device is unused then you should remove the Ethernet node from your device tree. g. -- Grant Likely, B.Sc., P.Eng.
