+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

  * iDiag debugfs file access methods
- */
-
-/*
- * iDiag PCI config space register access methods:
- *
- * The PCI config space register accessees of read, write, read-modify-write
- * for set bits, and read-modify-write for clear bits to SLI4 PCI functions
- * are provided. In the proper SLI4 PCI function's debugfs iDiag directory,
- *
- *      /sys/kernel/debug/lpfc/fn<#>/iDiag
- *
- * the access is through the debugfs entry pciCfg:
- *
- * 1. For PCI config space register read access, there are two read methods:
- *    A) read a single PCI config space register in the size of a byte
- *    (8 bits), a word (16 bits), or a dword (32 bits); or B) browse through
- *    the 4K extended PCI config space.
- *
- *    A) Read a single PCI config space register consists of two steps:
- *
- *    Step-1: Set up PCI config space register read command, the command
- *    syntax is,
- *
- *        echo 1 <where> <count> > pciCfg
- *
- *    where, 1 is the iDiag command for PCI config space read, <where> is the
- *    offset from the beginning of the device's PCI config space to read from,
- *    and <count> is the size of PCI config space register data to read back,
- *    it will be 1 for reading a byte (8 bits), 2 for reading a word (16 bits
- *    or 2 bytes), or 4 for reading a dword (32 bits or 4 bytes).
- *
- *    Setp-2: Perform the debugfs read operation to execute the idiag command
- *    set up in Step-1,
- *
- *        cat pciCfg
- *
- *    Examples:
- *    To read PCI device's vendor-id and device-id from PCI config space,
- *
- *        echo 1 0 4 > pciCfg
- *        cat pciCfg
- *
- *    To read PCI device's currnt command from config space,
- *
- *        echo 1 4 2 > pciCfg
- *        cat pciCfg
- *
- *    B) Browse through the entire 4K extended PCI config space also consists
- *    of two steps:
- *
- *    Step-1: Set up PCI config space register browsing command, the command
- *    syntax is,
- *
- *        echo 1 0 4096 > pciCfg
- *
- *    where, 1 is the iDiag command for PCI config space read, 0 must be used
- *    as the offset for PCI config space register browse, and 4096 must be
- *    used as the count for PCI config space register browse.
- *
- *    Step-2: Repeately issue the debugfs read operation to browse through
- *    the entire PCI config space registers:
- *
- *        cat pciCfg
- *        cat pciCfg
- *        cat pciCfg
- *        ...
- *
- *    When browsing to the end of the 4K PCI config space, the browse method
- *    shall wrap around to start reading from beginning again, and again...
- *
- * 2. For PCI config space register write access, it supports a single PCI
- *    config space register write in the size of a byte (8 bits), a word
- *    (16 bits), or a dword (32 bits). The command syntax is,
- *
- *        echo 2 <where> <count> <value> > pciCfg
- *
- *    where, 2 is the iDiag command for PCI config space write, <where> is
- *    the offset from the beginning of the device's PCI config space to write
- *    into, <count> is the size of data to write into the PCI config space,
- *    it will be 1 for writing a byte (8 bits), 2 for writing a word (16 bits
- *    or 2 bytes), or 4 for writing a dword (32 bits or 4 bytes), and <value>
- *    is the data to be written into the PCI config space register at the
- *    offset.
- *
- *    Examples:
- *    To disable PCI device's interrupt assertion,
- *
- *    1) Read in device's PCI config space register command field <cmd>:
- *
- *           echo 1 4 2 > pciCfg
- *           cat pciCfg
- *
- *    2) Set bit 10 (Interrupt Disable bit) in the <cmd>:
- *
- *           <cmd> = <cmd> | (1 < 10)
- *
- *    3) Write the modified command back:
- *
- *           echo 2 4 2 <cmd> > pciCfg
- *
- * 3. For PCI config space register set bits access, it supports a single PCI
- *    config space register set bits in the size of a byte (8 bits), a word
- *    (16 bits), or a dword (32 bits). The command syntax is,
- *
- *        echo 3 <where> <count> <bitmask> > pciCfg
- *
- *    where, 3 is the iDiag command for PCI config space set bits, <where> is
- *    the offset from the beginning of the device's PCI config space to set
- *    bits into, <count> is the size of the bitmask to set into the PCI config
- *    space, it will be 1 for setting a byte (8 bits), 2 for setting a word
- *    (16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 bytes), and
- *    <bitmask> is the bitmask, indicating the bits to be set into the PCI
- *    config space register at the offset. The logic performed to the content
- *    of the PCI config space register, regval, is,
- *
- *        regval |= <bitmask>
- *
- * 4. For PCI config space register clear bits access, it supports a single
- *    PCI config space register clear bits in the size of a byte (8 bits),
- *    a word (16 bits), or a dword (32 bits). The command syntax is,
- *
- *        echo 4 <where> <count> <bitmask> > pciCfg
- *
- *    where, 4 is the iDiag command for PCI config space clear bits, <where>
- *    is the offset from the beginning of the device's PCI config space to
- *    clear bits from, <count> is the size of the bitmask to set into the PCI
- *    config space, it will be 1 for setting a byte (8 bits), 2 for setting
- *    a word(16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4
- *    bytes), and <bitmask> is the bitmask, indicating the bits to be cleared
- *    from the PCI config space register at the offset. the logic performed
- *    to the content of the PCI config space register, regval, is,
- *
- *        regval &= ~<bitmask>
- *
- * Note, for all single register read, write, set bits, or clear bits access,
- * the offset (<where>) must be aligned with the size of the data:
- *
- * For data size of byte (8 bits), the offset must be aligned to the byte
- * boundary; for data size of word (16 bits), the offset must be aligned
- * to the word boundary; while for data size of dword (32 bits), the offset
- * must be aligned to the dword boundary. Otherwise, the interface will
- * return the error:
+ * ---------------------------------
  *
- *     "-bash: echo: write error: Invalid argument".
+ * All access methods are through the proper SLI4 PCI function's debugfs
+ * iDiag directory:
  *
- * For example:
- *
- *     echo 1 2 4 > pciCfg
- *     -bash: echo: write error: Invalid argument
- *
- * Note also, all of the numbers in the command fields for all read, write,
- * set bits, and clear bits PCI config space register command fields can be
- * either decimal or hex.
- *
- * For example,
- *     echo 1 0 4096 > pciCfg
- *
- * will be the same as
- *     echo 1 0 0x1000 > pciCfg
- *
- * And,
- *     echo 2 155 1 10 > pciCfg
- *
- * will be
- *     echo 2 0x9b 1 0xa > pciCfg
