Did some test. So with old I can always see the message "Uncompressing
Linux... done, booting the kernel."
Even if machine-id is not match or if bootargs are wrong regarding ttyS/ttyO.
With new kernel I can't see this message. So the question: Is
something changes there in uncompressing?
I am also a bit confused that I get this:

## Booting kernel from Legacy Image at 80000000 ...
   Image Name:   Linux-2.6.33
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1505256 Bytes = 1.4 MiB
   Load Address: 80008000
   Entry Point:  80008000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

and the kernel still has to be uncompressed?
