I found the problem: after this commit kernel become slightly bigger: it was 
0x5fd080 bytes, become 0x61b080 bytes.

Spike gives us 0x600000 free space only between start of physram to place where 
it puts DTB.
So DTB appears under our BSS section and we clear it during boot, so DTB is no 
longer valid and kernel get stuck in fdt header checking routine.

I'm currently looking for a solution and rearrangements, it will take some time.

Thanks

Ruslan
