[LinuxBIOS] Setting up memory registers

Hello everyone,
I noticed all the SDRAM registers are different. Some is 8bit, some  
16bit, and some 32 bit. I am working on my raminit.c file and and  
wondering if I sould be using the same bits as documented in the data  
sheet. It looks like in some of the other northbridge raminit.c files  
they are somewhat straight accross the board. Help?

Thanks - Joe
