This should all be runtime handled NAK.AFAIK you can't build a arm kernel that support arm6/armv7 and armv5. And I am not sure it will be possible one day.There are no plans to ever make it possible; there are too many significant differences between ARMv4, v5 architectures and ARMv6,v7 architectures to warrant making this runtime selectable.
Then bury this crap in platform files please not in the drivers/tty layer code. Make it a platform driver provided callback or something. Alan
