Improve support for the Intel 82371FB/SB/AB/EB/MB southbridge(s):
- Implement ISA related support:
- Initialize the RTC
- Enable access to all BIOS regions (but _not_ write access to ROM)
- Enable ISA (not EIO) support
- Without the *_isa.c file, the Super I/O init is never performed
- Improve IDE support:
- Add config option to enable Ultra DMA/33 for each disk
- Add config option to enable legacy IDE port access
- Implement hard reset support
- Implement USB controller support
- Various code cleanups and improvements
The code partially supports southbridges other than the 82371EB (but
which are very similar), more complete support will follow.
