Yes, but for now, the QE is marketed as an option for a few SOCs.  That 
means that when you select the SOC, you expect to see configuration 
options for that SOC.

This was addressed earlier.  On some boards, the QE is not wired to 
anything, so there's no point in enabling it.  Disabling it will prevent 
any unused QE code from becoming part of the kernel.
