Which boards are the users of this code?
...
It is used in the example designs of Altera NEEK and DE2 boards, which I provided for nios2 linux/uclinux on nios wiki. They are used by many nios2 users.
It may be used by other boards which support the GPIO access conventions of Linux. Though the GPIO access is not unified in u-boot currently, I think it should be the right direction to follow the conventions of Linux.
I mean, which board in U-Boot uses this code? I didn't find any.
The convention is not to add unused code. If there are no real users for this, the patch should be delayed until a board gets added that actually uses it.
Best regards,
Wolfgang Denk
