I think the most accurate answer is both "all" and "none" ... and I'm not trying to be funny or disrespectful in any way. It's just so very easy to replace peripherals with these FPGA based systems. >> The convention is not to add unused code.

However, the peripheral is not a standard Altera peripheral. In any case, it can essentially be used on any nios2 board as a replacement for the stock PIO peripheral. > These nios2 boards are now supported with the nios2-generic board > approach, like that of microblaze-generic, instead of adding every nios2 > board to u-boot mainline.

I asked Thomas to remove this peripheral from the Altera board tree because it was not associated with a _standard_ Altera peripheral. That is, anyone using the default configurations from Altera will never use this driver. However, the nios2 linux folks are very likely to use it (as a replacement). And, when they build u-boot, it will probably be configured using the nios2-generic board. So this isn't a rabbit in the hat ... the code will used. It's just not directly tied to a particular PCB from a traditional point of view.
