9d531dc3c1 - Add a new structure type for the ACPI 3.0 SMAP entry that includes the
optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
  system as an array of the ACPI 3.0 structure.  (On older systems, the
  attributes are given a value of zero.)  Note that the sysctl only
  exports the SMAP table if it is available via the metadata passed from
  the loader to the kernel.  If an SMAP is not available, an empty array
  is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
  binary to format the SMAP structures in a readable format similar to
  the format found in boot messages.

891131cb52 xen: implement hook to fetch and parse e820 memory map
e820 memory map is fetched using a hypercall under Xen PVH, so add a
hook to init_ops in oder to diverge from bare metal and implement a
Xen variant.

Approved by: gibbs
Sponsored by: Citrix Systems R&D

x86/include/init.h:
 - Add a parse_memmap hook to init_ops, that will be called to fetch
   and parse the memory map.

amd64/amd64/machdep.c:
 - Decouple the fetch and the parse of the memmap, so the parse
   function can be shared with Xen code.
 - Move code around in order to implement the parse_memmap hook.

amd64/include/pc/bios.h:
 - Declare bios_add_smap_entries (implemented in machdep.c).

x86/xen/pv.c:
 - Implement fetching of e820 memmap when running as a PVH guest by
   using the XENMEM_memory_map hypercall.

f643d4c50a - Re-shuffle the <machine/pc/bios.h> headers to move all kernel-specific
bits under #ifdef _KERNEL but leave definitions for various structures
  defined by standards ($PIR table, SMAP entries, etc.) available to
  userland.
- Consolidate duplicate SMBIOS table structure definitions in ipmi(4)
  and smbios(4) in <machine/pc/bios.h> and make them available to
  userland.

e8cee11d8d A simple rewrite of biossmap.c:
- Do not iterate int 15h, function e820h twice.  Instead, we use STAILQ to
store each return buffer and copy all at once.
- Export optional extended attributes defined in ACPI 3.0 as separate
metadata.  Currently, there are only two bits defined in the specification.
For example, if the descriptor has extended attributes and it is not
enabled, it has to be ignored by OS.  We may implement it in the kernel
later if it is necessary and proven correct in reality.
- Check return buffer size strictly as suggested in ACPI 3.0.

ae8e7ec2a3 - Add constants for the different memory types in the SMAP table.
- Use the SMAP types and constants from <machine/pc/bios.h> in the boot
  code rather than duplicating it.

0b265b33d3 Make the facility for recognizing BIOS-signatures more general
and return a printable representation.

This fixes recognition of the PC Engines WRAP and improves the
recognition of the Soekris boards (Bios version can now be
seen in the dmesg output for instance).

Also, add watchdog support for PCM-582x platforms.

09b56c9832 Severely strip down the repocopied i386/bios.c and bios.h files. It turns
out that bios_sigsearch() etc is useful for finding tables in roms.

ee8370535a - Use the correct devclass name ("acpi" vs "ACPI") to detect if acpi0 is
present and thus that the PnPBIOS probe should be skipped instead of
  having ACPI zero out the PnPBIOStable pointer.
- Make the PnPBIOStable pointer static to i386/i386/bios.c now that that is
  the only place it is used.

2037893300 The general conesnsus on irc was that pci bios for config registers
and such was just a bad idea and one that users should be forced to
enable if they want it.  This patch introduces a hw.pci.enable_pcibios
tunable for those people.  This does not impact the pcibios interrupt
routing at all.

43b494595e More updates to the ACPI code:
- Move all register I/O into acpi_io.c
 - Move event handling into acpi_event.c
 - Reorganise headers into acpivar/acpireg/acpiio
 - Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
 - Allocate all resources (except those detailed only by AML)
   as real resources.  Add infrastructure that will make adding
   resource support to AML code easy.
 - Remove all ACPI #ifdefs in non-ACPI code
 - Removed unnecessary includes
 - Minor style and commenting fixes

087c82acdb Some more i386-only BIOS-friendliness:
- Add support for using the PCI BIOS functions for configuration space
   accesses, and make this the default.

 - Make PNPBIOS the default (obsoletes the PNPBIOS config option).

 - Add two new boot-time tunables to disable each of the above.
