Patch Set #172:
The vendor firmware used some I/O port writes to seemingly 'trigger' the EC to handle commands. However, a different firmware phase (DXE) uses `Stall(15)` equivalently - in coreboot, this would be `mdelay` - and reads from the port always return 0xFF.
My mistake, microseconds: `udelay`.
Therefore, I will remove this.
Essentially, it looks like an ugly way to pause execution. Perhaps the I/O serves some purpose, but if actual `Stall` is equivalent, I don't see it.
