Hi!

I updated my dev tree to the latest trunk version of nutos. I found some interesting work has been done and so I started to port my device drivers to this new system.
Great idea to use the configurator to select which CS is used by what chip on an SPI bus and if its CS is high or low active.
But... I miss the option to select the SPI bus itself... 

Background:
I ported the 7segspi device that I use for the display in a thermal controller unit. It is a AS1108 that interfaces a 3 digit 7 segment LED display to the SPI bus.

While inspecting the needed changes to my code I stumbled upon the fact, that all SPI connected devices miss an option to select the bus where they are connected to.

I miss another thing, that is you cannot select the AT24C EEPROM for beeing a config memory to the system. But as I (re)wrote most of that code, I think I have to fix that myself :)

Best regards and a nice weekend
Ulrich
