to remember updating manually. Converted this into HAVE_... properties, which
will be inherited automatically if someone copies a chipset to create a new

This patch implements a full SDRAM buffer strength programming algorithm in
set_dram_buffer_strength(), checked against my P2B-LS factory BIOS. With this
in place, I now have 133MHz (!) stability with three 256MB PC133 modules, and
can boot Fedora 11 all the way to the init daemon (actually upstart, but that's
another story). Not to login prompt yet. We'll find out why later.
This again assumes a 4-DIMM board because that's all I have. I need someone
with a 3-DIMM board to test it.
As a bonus, there's a big comment block within that illustrates the algorithm.

options for as long as newconfig still exists) which can be enabled

The respective menu items only appear if a board is selected where the

Major changes:
1. Separate resource allocation into:
A. Read Resources
B. Avoid fixed resources (constrain limits)
C. Allocate resources
D. Set resources
Usage notes:
Resources which have IORESOURCE_FIXED set in the flags constrain the placement
of other resources. All fixed resources will end up outside (above or below)
the allocated resources.
Domains usually start with base = 0 and limit = 2^address_bits - 1.
I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is
still there for resources. Some platforms may want to change that, but I didn't
want to break anyone's board.
Resources are allocated in a single block for memory and another for I/O.
Currently the resource allocator doesn't support holes.

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).
