Pi5 MESA 7c80: mesaflash can't see the card.

On the latest Linuxcnc images SPI should be enabled by default, this was an issue I had with the previous releases.
You specify which spidev mesaflash uses on the command line switch as the --addr, spix can be forced to use a particular SPI interface. The Linuxcnc docs for spix are a good read as it points everything out.

Do not change the subject tittle as it makes it impossible to find when searching.
Thank you.
