The patch worked, i had to set the decoder scratchpad size to 50335340, which 
seems quite much to me, but there was no more error on "Uncompressing to 
RAM".

To add that also into the coreboot v2 reprository, and not just in v3.

But booting with LAB didn't work, the last lines which i get for now are:
"rom_stream: 0xffc00000 - 0xfffe7fff
Uncompressing to RAM 0x0100000"

Maybe, as i set the scratchpad size that high, it takes really long to 
decompress the image to the RAM. I waited about 2 minutes and nothing more 
happened, i think that should be enaugh time to decompress 4MB into the RAM.

Any idea what is wrong with my image, or what could be done to get debug 
informations?
