Hi Mikhail,

The board fixup is a board-specific thing.  Are you doing that in your 
board configuration?

If you have CONFIG_OF_BOARD_SETUP defined (if you don't that probably is 
the answer to your missing #define question), you can run
   fdt boardsetup
and then
   fdt print /
to see what the fixed up tree looks like.

You can also run the bootm command step-by-step (some steps may not 
apply to your board)...

bootm start
bootm loados
bootm ramdisk
bootm fdt
bootm bdt
bootm cmdline
bootm prep

Print out the tree:
fdt print /

(last step is...)
bootm go

Best regards,
gvb
