MIPS: Alchemy: devboard register abstraction
All Alchemy development boards have external CPLDs with a few registers
in them. They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.
This patch
- adds a primitive facility to initialize and use these external
registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
headers in a central place.
