## Booting kernel from Legacy Image at 22200000 ...
   Image Name:   Angstrom/2.6.30/at91sam9263ek
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    2074380 Bytes =  2 MB
   Load Address: 20008000
   Entry Point:  c0008000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

Starting kernel ...

And HANG...

Then I changed kernel.bbclass so LoadAddress == EntryPoint and that 
hangs at loading kernel (which was expected). So it looks like that 
patch is not so safe to use...
