9da69f83d9 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.

1410c2d219 Intel 82371EB: Add IDE init support.
In a mainboard's Config.lb file you can configure whether the primary
and/or secondary IDE interfaces shall be enabled.

Also, various fixups in the rest of the southbridge code, most notably
the early SMBus code, plus some documentation improvements.

4cb85533dd Init for the Intel 82371EB southbridge: make all ROM/BIOS regions
accessible (but not writable), so that reading/loading a payload
from that area can work (for instance).

d436a4b4bc Correct the RAM checking code to _not_ check the range from 640 KB - 1 MB,
as that is not RAM but used for other stuff.

First try at PCI init added to src/mainboard/tyan/s1846/Config.lb.

Use a real payload (FILO) per default now.

Note: this cannot boot a payload, yet, but it gets a lot further now.
