That's what I also tried. But from the ref manual I got no idea.
When we do not find a hy to deassert the chip select manually, we cannot
avoid this read.

It seems that the mainline linux only implements a GPIO based SPI driver.
So we cannot take it for reference.

I'm wonderng how this works on the Denx' M28EVK.
