Both CONFIG_USE_INIT and USE_DCACHE_RAM were added by me for PPC  
support. I don't mind you using them for x86 CAR as long as they  
remain available for PPC. I would prefer if you didn't change the  
default options.

CONFIG_USE_INIT has nothing to do with CAR. It's to include certain  
files that are needed for the PPC initialization process, but that  
are not supported in x86.

USE_DCACHE_RAM enables CAR for those boards that support it. Some,  
like the 970, already have ram enabled when they start so don't need  
CAR support.
