Here I see:
"In the Cortex-A9 MPCore Technical Reference Manual I found the SMPnAMP
Signal which switches between SMP or AMP for each Processor."
While it is encouraging to see that AMP _is_ a supported feature with
A9, I fail to understand what the use of making this known to the
hardware might be.
I supposed AMP vs SMP would be just a matter of software.
