I will try to explain again my problem.
1. vmlinux.bin loaded into ram (bin2vmem)
2. Processor is reading from addresses 0x100-0x118, high addresses like
0x17E000, C00FE948, 0x42088, C01401A8, which according to Your replies is
probably correct.
2. I see nothing on uart console. Processor doesn't write to uart16550_0,
its address 0x9000000 does not appear on wishbone bus.

Maybe there is something wrong in dts, or bootargs? Do i have to edit
initramfs.devnodes and add nod to /dev/ttyS0?

I enclose 
.config <http://openrisc.2316802.n4.nabble.com/file/n4642100/.config>      
- from kernel building
simple.dts <http://openrisc.2316802.n4.nabble.com/file/n4642100/simple.dts>  
- used device tree
sim.log <http://openrisc.2316802.n4.nabble.com/file/n4642100/sim.log>      
- log from simulation using or32-elf-sim
