Hi,
I've been playing with spi on mpc8313e and have some things on
spi-fsl-spi.c:
Is QE useful on 8313?
I've tried it (using cpu-qe in my dts file) and see in the boot log
that it
is used, but I do not really see any effect when it comes to
performance or
cpu usage.
8313 does not have a QE. The "effect" when you do have a QE and use it
is that you can talk to the peripherals that are connected to the QE.
The effect when you modify the device tree to say the board has
hardware that it doesn't have is generally bad.
