I get some problem at making coreboot.rom smaller. Normal and fallback get 
128kb before. I tried two different possibilities to get space for it, but 
both failed.

I need 57344b. But taking 57344/2 out of both raises error "XIP_ROM_BASE is 
not multiple of XIP_ROM_SIZE". And reducing one of them about 57344b make 
breaks because of overleaping sections.

Is there any overview how to use all these option in Config.lb? I think I 
don't understand the structur of all these options and their results.
