Coreboot supports 945 North bridge made by Intel. The data sheet of this IC mentions some registers while there is no table or some description about them like: FSBSNPCTL, FSBPMC4, C0ODT, C1AIT(Channel 1 Adaptive Idle Timer Control),....many registers... Where can i find the technical details of these registers? How Coreboot is using FSBSNPCTL in src/northbridge/intel/i945/early_init.c? I wonder if any one can direct me to find the necessary information.

The documentation of those registers is not publically available, I am afraid to say.
You will need a couple of NDAs in order to get to that documentation.

i am afraid that the OEM would not support any documents about the CPUs. The way you can get the spec is from Intel.
