Yes. I want to put lines like:
#define RADIO_2056_RX0				(0x6 << 12)
in my radio_2056.h

I do. I see many advantages of that plus most of the code is already
here coming from RE.

Finishing N-PHY support in b43 does not need much work plus:
1) We support SSB devices
2) We support older (LP/G-phy) devices
3) We share infrastructure (easier to maintain)
4) We probably could support modes like AP
