This is the InterControl custom device based on the MPC5200B chip.
Signed-off-by: Grzegorz Bernacki <gjb(a)semihalf.com>
---
Version 5:
- removed unnecessary braces
- changed out32/in32 to out_be32/in_be32
Version 4:
- rebased to Ben's FEC changes
Version 3:
- updated (c)
Version 2:
- use I/O accessor functions instead of volatile pointer
- set ethernet address only if not set in environment
- add some comments and some style cleanup
