I have finally found what I was doing wrong.
Checking mem as you suggested I found that
the breakpoint I was setting to virtual
address 0xc00035f8 has to be set to physical
0x000035f8, otherwise it doesn't stop.

So problem was here with BDI2000 debugging,
MMU and me. Sorry about my misknowledge.

Nevertheless kernel is still hanging.
Now I have continued debugging and I have
arrived to start_kernel ... and go on till
do_basic_setup. But still seeing nothing in
the serial console before kernel hanging.

I think I have some problem with serial
console I have to solve before going on.
