the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

I cleaned up the patch and moved most of the dsdt.dsl and
acpi_tables.c into the southbrige/northbridge directory.
Updated patch should fix abuild error and incorporates suggestions
on irc by uwe (thanks for the comments).
Thanks to Idwer Vollering <vidwer@gmail.com> for the original patch.
Tested:
Linux (poweroff, powerbutton event)
XP (poweroff, powerbutton event)
Abuild-tested

- Add enable_intel_82093aa_ioapic() which enables IOAPIC usage in the
Intel 82371EB southbridge (sets the proper chip-select) and sets an
IOAPIC ID.
- We only call enable_intel_82093aa_ioapic() if a board does "select IOAPIC"
as on 82371EB-based boards the IOAPIC is an external chip (not integrated
in the southbridge) and it's only populated on multi-CPU boards.
That is, we cannot unconditionally enable it, only on SMP-capable boards.
- Due to the reason explained above, remove "select IOAPIC" from
src/southbridge/intel/i82371eb/Kconfig, and add it to
src/mainboard/asus/p2b-d/Kconfig.
- Also set CONFIG_MAX_PHYSICAL_CPUS to 2 on ASUS P2B-D. There are two
CPU sockets (Slot 1) and each CPU can only have one core, multi-core CPUs
didn't exist in that era (CONFIG_MAX_CPUS was set to 2 already).
- Drop useless/duplicated enable_lapic() call from ASUS P2B-D's romstage.c,
that function is always called if either CONFIG_SMP and/or CONFIG_IOAPIC
are set.
- Rework ASUS P2B-D mptable.c to fix a number of things:
- Convert it to use mptable_write_buses() as all mptable.c files should do.
- Fix incorrect IOAPICID (it's 0x11 for the external 82093AA IOAPIC).
- Fix a bunch of hardcoded bus IDs, remove incorrect entries, etc.
This is build-tested on ASUS P2B-D, and also boot-tested successfully there.
On Linux I now get two entries in /proc/cpuinfo (where only one appeared
before this patch), i.e. both populated CPUs are found.

As both ioapic.h and acpi.h define a macro named "NMI", rename one
of them (NMI -> NMIType in acpi.h).

- Add static and const where possible.
- Turn some #warning entries into TODO comments.
- Add missing prototypes.
- Remove unused variables.
- Fix printf arguments or cast them as needed.
- Make sconfig output look better. Drop useless "PARSED THE TREE" output.
- Print "(this may take a while)" while building romcc. Add missing "\n".

TODO
- x86emu need (imo) some common header with prototypes at least
- clog2, ulzma, hardwaremain prototypes added by this patch probably should
be moved to some header too.
- in src/devices/device_util.c prototype is before function because seems,
it is used only within same file, if not it should be moved to debug
section of prototypes in include/device/device.h

in very early stages, otherwise the boot may hang like this because
the CBFS headers cannot be found/accessed:
Uncompressing coreboot to RAM.
Jumping to image.
Check CBFS header at fffedfe0
magic is ffffffff
ERROR: No valid CBFS header found!
CBFS: Could not find file fallback/coreboot_ram
Jumping to image.
This patch enables full ROM access on all 440BX boards right after the
serial init (and before CBFS headers are parsed).
Build-tested and runtime-tested on ASUS P2B-F.

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.

- 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.
