MFC r326276:

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.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Fxi a bunch of typos.

Move sys/pccard/*.h here.

Remove unnecessary pccard/cardinfo.h include.

The original programs that this code was lifted from (pccardd and
pccardc) parsed data to make decisions about stuff related to card
configuration.

The purely CIS dumping aspect of this program obviates the need for
such parsing. Save some space and don't parse the data anymore for
configuration purposes. Just parse it to print an interpreatation of
it.

make this warns=5 clean

Move dumpcis to its own directory, start to decouple from the
pccardc/pccardd history.

Fix a minor printing bug that prints incorrect information for memory
block sizes.

This orginally worked in PAO-3 and worked on their r330 branch but got
broken in PAO-3 around December 1998!

MFPAO3. Improvement of of pccard cis tuple parsing capability.
- Fixed bogus CIS tuple dumping (Network node ID, IRQ modes and etc.)
- Include telling drivers ethernet address if Network node ID
tuple is available. This is usefull for some bogus ehter cards which
can't get correct ethernet address from CIS tupple.

$Id$ -> $FreeBSD$

When printing out V1 info, make sure that there is additional info
before printing it. Terminate when we come to a 0xff byte. This
allows there to be zero or more additional info fields printed
correctly. Before, the old code would print bogons or dump core when
presented with this case.

I don't know what the spec says about this, exactly, but this allows
me to do a dumpcis of my non-ATA AMP 4M FLASH cards w/o pccardc
dumping core.

- Include <pccard/cardinfo.h> instead of <pccard/card.h> which was recently
renamed.

Use err(3). Add usage()s.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Use the defines and macros defined in /sys/pccard/cis.h to make the code
easier to understand. LOTS more work needed in this area.

Inspired by: The Nomad code

Added RCS Id and BSD-style copyrights to individual files.

Run indent on all these files to make them more readable. (I also went
through by hand and cleaned up some indent bogons.)

Shut a bunch of warnings.

The userland part of Andrew McRae's PCMCIA/PCCARD code.

This is not quite finished yet, and therefore I have not added it to the
usr.sbin/Makefile yet.
I collected a bunch of Andrews small programs into one: pccardc /phk
