Hi Leonid,

The only thing I had to do with the kernel 2.6.19 from denx.de (but this was
the 2.6.19 don't know about newer ones) is the typical board_info struct
patch:

diff -Naur linux-2.6.19/arch/ppc/platforms/4xx/xilinx_ml403.h
../linux-2.6.19-xemac/arch/ppc/platforms/4xx/xilinx_ml403.h

 /* Some 4xx parts use a different timebase frequency from the internal
clock.
 */

Greetings,
