[LinuxBIOS] E7501 SDRAM command bug?

[Ronald G. Minnich]

I would need to look at that code more, but what is typically done is the 
boundary registers are programmed so that the ram "size" is 0x4000000 and 
all the commands for setup are sent to the ram. Once all the ram init is 
done, then the actual row boundaries are set. 

We do it this way because it saves a lot of computation that is not really 
needed.
