Integrating device driver into HAL

Thanks for the comments. I finally managed to get the driver integrated and work but not without some experimenting.

There may be other ways to achieve the same result, but in the end I found that ‘publishing’ the device as user logic through SOPCB was required. This created a bunch of sub directories with the prefix user_logic. If I then prefixed my *_INIT and *_INSTANCE macros and all driver files with USER_LOGIC and put the drivers in the newly created sub folders things seem to work as required.

I don’t see that mentioned in the Nios II Software Developers any where…..
