Ram-init: Intel i945: sdram_detect_cas_latency_and_ram_speed

[Mohit Gupta]

I am trying to understand ram initialization process for intel i945 chipset. Would some be able to guide me as what sdram_detect_cas_latency_and_ram_speed is trying to do. I am a newbie, hence, entitled to ask stupid question :)
