Hum, ... I think I have a problem.
With the default register value (that I get a reset) the CS line is
deselected when the CS is high.
So at reset I would need to set my 4 CS lines to high in order to be
able to drive them low later.
So during the "reset" I need to set my 4 CS line to 1 but

The i.MX SPI device was not de-asserting the CS line at the end of
memory access.
This triggered a SIGSEGV in Qemu when the sabrelite emulator was acessing
a SPI flash memory.
Whith this path the CS signal is correctly asserted and deasserted arround
memory access.
Assertion level is now based o
