Add mrsasutil(8) as alias to mfiutil(8)

mfiutil(8) in theory can work on devices attached to mrsas(4) but
mrsas(4) is missing the FreeBSD mfi(4) ioctl support. Once that
support is added to mrsas(4) then mrsasutil(8) can manage mrsas(4)
attached devices. So this commit depends on that. When mrsasutil(8)
is run it automatically opens /dev/mrsas0 instead of /dev/mfi0.
Add -D <device> and -t <type> flag to optionally specify mrsas or mfi to
work with the existing -u <unit>. Device is the device node with or
without /dev/

various: general adoption of SPDX licensing ID tags.

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.

No functional change intended.

Now that mfi(4) header files uses the absolute number of entries to
make the mfi_array 288 bytes, remove this magic number and the
calculations that go with it. Use the MFI_MAX_ROW_SIZE and
sizeof(struct mfi_array) in place of the prior calculations.

Change reporting a disk as "SYSTEM" when it is a "JBOD" reported
by the firmware and MegaCli. A JBOD appears as /dev/mfisyspd<n>.

This also means the mfiutil command to "create jbod" is now a
little confusing since a RAID per drive is not really what LSI
defines JBOD to be. In the future mfiutil should have an option
to create real JBOD's and enable that option in RAID controllers
that support it. In testing, it appears the RAID cache is not
used with JBOD but is with the RAID per disk. When this is
implemented more testing should be done to determine the pro's and
con's of JBOD versus RAID per disk.

In build_volume(), check if arrays is allocated before traversing its
items. While parsing the arrays input, it's possible that we reach the
error path before initializing the 'arrays' pointer, which in turn leads
to a NULL deference.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Merge mfiutil

Approved by: re

ntroduce mfiutil, a basic utility for managing LSI SAS-RAID & Dell PERC5/6
controllers. Controller, array, and drive status can be checked, basic
attributes can be changed, and arrays and spares can be created and deleted.
Controller firmware can also be flashed.

This does not replace MegaCLI, found in ports, as that is officially sanctioned
and supported by LSI and includes vastly more functionality. However, mfiutil
is open source and guaranteed to provide basic functionality, which can be
especially useful if you have a problem and can't get MegaCLI to work.
