Various 440BX and Tyan S1846 related minor changes and fixes (trivial):
- Only check the RAM from 0 - 640 KB and 768 KB - 1 MB now. That's
available on all boards, regardless of what DIMMs you use.
Tested on the Tyan S1846, works fine.
- Properly set the PAM registers to allow the region from 768 KB - 1 MB
to be used as normal RAM (required for the above).
- Document all of this properly. Add/improve other documentation, too.
- Simplify and document code in northbridge.c.
- Cosmetics and coding style.
