We should not be leaking these interfaces to the outside world given
that it's much easier for third-party components to use the devel/atf
package from ports.
As a side-effect, we can also drop the ATF pkgconfig and aclocal files
from the base system. Nothing in the base system needs these, and it
was quite ugly to have to get them installed only so that a few ports
could build. The offending ports have been fixed to depend on
devel/atf explicitly.

Makefiles are evaluated without building things. In a normal build,
the prerequisites would be built, and CC would be an actual thing. In
an INDEX build, though, they don't exists. Redirect stderr to get rid
of annoying messages, and assume that the compiler version is 0 if the
actual compiler can't tell us. Do this in preference to guessing based
on numbers because gcc410 might be 4.10, or 4.1.0 and without
carefully crafted special knowledge we differentiate between them
easily (also ming-gcc has no clues at all). Elsewhere, don't trust
the compiler version if it is 0.

Targets thus marked are supposed to run even with -n.
As such they should not do anything except run the sub-make.
Use an intermediate target _* to associate with _SUBDIR and which

This is not a comprehensive list, as the variables themselves are spread
out over multiple files, but it is a start.
Add a section to make.conf noting that variables may be set there that
affect ports builds, but refer to ports.7 and elsewhere for the actual
listing; any listing in make.conf.5 would likely become out of date
fairly quickly.

cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.
mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).
It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).
Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.
Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.

This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.
Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.
o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.
o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.
