The original implementation only supports getting the address from legacy
BIOS (by searching for the SMBIOS_SIG pattern in a fixed address space).
Try to get the SMBIOS table from EFI through efirt (EFI Runtime Services)
firstly. Continue to search in the legacy BIOS if a NULL address is
returned from EFI.
By this way the ipmi function supports both legacy BIOS and UEFI systems.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
ipmi_isa_attach. This keeps unintended but harmless noise about "ipmi1"
from appearing in the boot up sequence.

no longer have the parent in the device tree. This causes the identify
function in ipmi_isa.c to attempt to probe and poke at the ISA IPMI interface
Move the check for ipmi_attached out of the ipmi_isa_attach function and into
the ipmi_isa_identify function. Remove the check of the device tree for
ipmi devices attached.
This probing appears to make Broadcom management firmware on Dell machines
crash and emit NMI EISA warnings at various times requiring power cycles
of the machines to restore.
Bump MAX_TIMEOUT to 6 seconds as a hack for super slow IPMI interfaces that
need longer to respond to our intial probes on startup.
Tested on Dell R410, R510, R815, HP DL160G6

config info. from device.hints. Some machines have ipmi controllers
that do not have attachment info in either PCI, SMBIOS or ACPI.
This idea was hacked together by me and then done properly by
jhb.

- Split out the communication protocols into their own files and use
a couple of function pointers in the softc that the commuication
protocols setup in their own attach routine.
- Add support for the SSIF interface (talking to IPMI over SMBus).
- Add an ACPI attachment.
- Add a PCI attachment that attaches to devices with the IPMI interface
subclass.
- Split the ISA attachment out into its own file: ipmi_isa.c.
- Change the code to probe the SMBIOS table for an IPMI entry to just use
pmap_mapbios() to map the table in rather than trying to setup a fake
resource on an isa device and then activating the resource to map in the
table.
- Make bus attachments leaner by adding attach functions for each
communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.)
that setup per-interface data.
- Formalize the model used by the driver to handle requests by adding an
explicit struct ipmi_request object that holds the state of a given
request and reply for the entire lifetime of the request. By bundling
the request into an object, it is easier to add retry logic to the various
communication backends (as well as eventually support BT mode which uses
a slightly different message format than KCS, SMIC, and SSIF).
- Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE.
- Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool
on FreeBSD/amd64.
- Add ipmi(4) to i386 and amd64 NOTES.
