It seems we are not using this function anywhere else. Do we want to remove this function? Probably not as part of this revert, but a different CL?

I know for a fact that FSP will re-init the UART. This doesn't cause a problem since it's a very simple controller. Since FSP is huge, I'm not sure what else it is initializing. I haven't seen a problem though...
I think FSP sets up its own exception handlers as well. I haven't actually tried to force an exception in this callback though.

What happens if FSP re-inits any of the IP blocks that coreboot is trying to leverage at this point?
Does FSP reconfigure anything in the BSP while it is executing and then put it back before returning control to coreboot?

PS3, Line 32: 0x100f
What about moving this a bit away from the other indices so it can grow on its own when necessary? Maybe use (0x3000 + (n)) or something like that? (AFAIK any number works here and it makes no difference, but would be good for Andrey to confirm.)

Not really sure what you mean by cr50 specific. They are specific to this code here which creates them (and the userspace code which will use them). We could pick any index (in the available space) we want, and you could have these on a non-cr50 TPM as well.

I think you want < here or you'll end up with 5 counters.
