sys: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. |

Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

Merge from projects/mips to head by hand:
r201881 | imp | 2010-01-08 20:08:22 -0700 (Fri, 08 Jan 2010) | 3 lines Rename mips_pcpu_init to mips_pcpu0_init since it applies only to the BSP. Provide a missing prototype. r200343 | imp | 2009-12-09 18:44:11 -0700 (Wed, 09 Dec 2009) | 4 lines Get the sense of this right. We use uintpr_t for bus_addr_t when we're building everything except octeon && 32-bit. As note before, we need a clearner way, but at least now the hack is right. r199760 | imp | 2009-11-24 10:15:22 -0700 (Tue, 24 Nov 2009) | 2 lines Add in Cavium's CID. Report what the unknown CID is. r199754 | imp | 2009-11-24 09:32:31 -0700 (Tue, 24 Nov 2009) | 6 lines Include opt_cputype.h for all .c and .S files referencing TARGET_OCTEON. Spell ld script name right. r199599 | imp | 2009-11-20 09:32:26 -0700 (Fri, 20 Nov 2009) | 2 lines Another kludge for 64-bit bus_addr_t with 32-bit pointers... r199496 | gonzo | 2009-11-18 15:52:05 -0700 (Wed, 18 Nov 2009) | 5 lines - Add cpu_init_interrupts function that is supposed to prepeare stuff required for spinning out interrupts later - Add API for managing intrcnt/intrnames arrays - Some minor style(9) fixes r198958 | rrs | 2009-11-05 11:15:47 -0700 (Thu, 05 Nov 2009) | 2 lines For XLR adds extern for its bus space routines r198669 | rrs | 2009-10-30 02:53:11 -0600 (Fri, 30 Oct 2009) | 5 lines With this commit our friend RMI will now compile. I have not tested it and the chances of it running yet are about ZERO.. but it will now compile. The hard part now begins, making it run ;-) r198666 | imp | 2009-10-29 18:37:50 -0600 (Thu, 29 Oct 2009) | 2 lines Add some newer MIPS CO cores. r198665 | imp | 2009-10-29 18:37:04 -0600 (Thu, 29 Oct 2009) | 4 lines db_expr_t is really closer to a register_t. Submitted by: bde@ r198531 | gonzo | 2009-10-27 18:01:20 -0600 (Tue, 27 Oct 2009) | 3 lines - Remove bunch of declared but not defined cach-related variables - Add mips_picache_linesize and mips_pdcache_linesize variables r198354 | neel | 2009-10-21 20:51:31 -0600 (Wed, 21 Oct 2009) | 9 lines Get rid of the hardcoded constants to define cacheable memory: SDRAM_ADDR_START, SDRAM_ADDR_END and SDRAM_MEM_SIZE Instead we now keep a copy of the memory regions enumerated by platform-specific code and use that to determine whether an address is cacheable or not. r198310 | gonzo | 2009-10-20 17:13:08 -0600 (Tue, 20 Oct 2009) | 5 lines - Commit missing part of "bt" fix: store PC register in pcb_context struct in cpu_switch and use it in stack_trace function later. pcb_regs contains state of the process stored by exception handler and therefor is not valid for sleeping processes. r198207 | imp | 2009-10-18 08:57:04 -0600 (Sun, 18 Oct 2009) | 2 lines Undo spamage of last MFC. r198206 | imp | 2009-10-18 08:56:33 -0600 (Sun, 18 Oct 2009) | 3 lines _ALIGN has to return u_long, since pointers don't fit into u_int in 64-bit mips. r198182 | gonzo | 2009-10-16 18:22:07 -0600 (Fri, 16 Oct 2009) | 11 lines - Use PC/RA/SP values as arguments for stacktrace_subr instead of trapframe. Context info could be obtained from other sources (see below) no only from td_pcb field - Do not show a0..a3 values unless they're obtained from the stack. These are only confirmed values. - Fix bt command in DDB. Previous implementation used thread's trapframe structure as a source info for trace unwinding, but this structure is filled only when exception occurs. Valid register values for sleeping processes are in pcb_context array. For curthread use pc/sp/ra for current frame r198181 | gonzo | 2009-10-16 16:52:18 -0600 (Fri, 16 Oct 2009) | 2 lines - Get rid of label_t. It came from NetBSD and was used only in one place r198154 | rrs | 2009-10-15 15:03:32 -0600 (Thu, 15 Oct 2009) | 10 lines Does 4 things: 1) Adds future RMI directories 2) Places intr_machdep.c in specfic files.arch pointing to the generic intr_machdep.c. This allows us to have an architecture dependant intr_machdep.c (which we will need for RMI) in the machine specific directory 3) removes intr_machdep.c from files.mips 4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We may need to look at finding a better place to put this. But first I want to get this thing compiling. r198066 | gonzo | 2009-10-13 19:43:53 -0600 (Tue, 13 Oct 2009) | 5 lines - Move stack tracing function to db_trace.c - Axe unused extern MipsXXX declarations - Move all declarations for functions in exceptions.S/swtch.S from trap.c to respective headers r197685 | gonzo | 2009-10-01 14:05:36 -0600 (Thu, 01 Oct 2009) | 2 lines - Sync caches properly when dealing with sf_buf r196215 | imp | 2009-08-14 10:15:18 -0600 (Fri, 14 Aug 2009) | 6 lines (u_int) is the wrong type here. Use unsigned long instead, even though that's only less wrong... r196199 | imp | 2009-08-13 13:47:13 -0600 (Thu, 13 Aug 2009) | 7 lines Use unsigned long instead of unsigned for the integer casts here. The former works for both ILP32 and LP64 programming models, while the latter fails LP64. r196089 | gonzo | 2009-08-09 19:49:59 -0600 (Sun, 09 Aug 2009) | 4 lines - Make i/d cache size field 32-bit to prevent overflow Submited by: Neelkanth Natu r195582 | imp | 2009-07-10 13:07:07 -0600 (Fri, 10 Jul 2009) | 2 lines fix prototype for MipsEmulateBranch. r195581 | imp | 2009-07-10 13:06:43 -0600 (Fri, 10 Jul 2009) | 2 lines Better definitions for a few types for n32/n64. r195580 | imp | 2009-07-10 13:06:15 -0600 (Fri, 10 Jul 2009) | 5 lines Fixed aligned macros... r195478 | gonzo | 2009-07-08 16:28:36 -0600 (Wed, 08 Jul 2009) | 5 lines - Port busdma code from FreeBSD/arm. This is more mature version that takes into account all limitation to DMA memory (boundaries, alignment) and implements bounce pages. - Add BUS_DMASYNC_POSTREAD case to bus_dmamap_sync_buf r195440 | imp | 2009-07-08 00:01:37 -0600 (Wed, 08 Jul 2009) | 2 lines Fix atomic_store_64 prototype for 64-bit systems. r195392 | imp | 2009-07-05 20:27:03 -0600 (Sun, 05 Jul 2009) | 3 lines The MCOUNT macro isn't going to work in 64-bit mode. Add a note to this effect. r195391 | imp | 2009-07-05 20:22:51 -0600 (Sun, 05 Jul 2009) | 3 lines Provide a macro for PTR_ADDU as well. We may need to implement this differently for N32... Use PTR_ADDU in DO_AST macro. r195390 | imp | 2009-07-05 20:22:06 -0600 (Sun, 05 Jul 2009) | 4 lines Change the addu here to daddu. addu paranoina prodded by: jmallet@ r195382 | imp | 2009-07-05 15:16:26 -0600 (Sun, 05 Jul 2009) | 5 lines addu and subu are special. We need to use daddu and dsubu here to get proper behavior. Submitted by: jmallet@ r195370 | imp | 2009-07-05 09:20:16 -0600 (Sun, 05 Jul 2009) | 6 lines The SB1 has cohernet memory, so add it. Also, Maxmem is better as a long. Submitted by: Neelkanth Natu r195369 | imp | 2009-07-05 09:19:28 -0600 (Sun, 05 Jul 2009) | 4 lines The SB1 needs a special value for the cache field of the pte. Submitted by: Neelkanth Natu r195368 | imp | 2009-07-05 09:18:06 -0600 (Sun, 05 Jul 2009) | 2 lines compute the areas to save registers in for 64-bit access correctly. r195367 | imp | 2009-07-05 09:17:11 -0600 (Sun, 05 Jul 2009) | 3 lines First cut at 64-bit types. not 100% sure these are all correct for N32 ABI. r195366 | imp | 2009-07-05 09:16:27 -0600 (Sun, 05 Jul 2009) | 3 lines Trim unreferenced goo. SDRAM likely should be next, but it is still referenced. r195365 | imp | 2009-07-05 09:13:24 -0600 (Sun, 05 Jul 2009) | 9 lines First cut at atomics for 64-bit machines and SMP machines. # Note: Cavium provided a port that has atomics similar to these, but # that does a syncw; sync; atomic; sync; syncw where we just do the classic # mips 'atomic' operation (eg ll; frob; sc). It is unclear to me why # the extra is needed. Since my initial target is one core, I'll defer # investigation until I bring up multiple cores. syncw is an octeon specific # instruction. r195359 | imp | 2009-07-05 02:14:00 -0600 (Sun, 05 Jul 2009) | 4 lines Bring in cdefs.h from NetBSD to define ABI goo. Obtained from: NetBSD r195358 | imp | 2009-07-05 02:13:19 -0600 (Sun, 05 Jul 2009) | 4 lines Pull in machine/cdefs.h for the ABI definitions. Provide a PTR_LA, ala sgi, and use it in preference to a bare 'la' so that it gets translated to a 'dla' for the 64-bit pointer ABIs. r195357 | imp | 2009-07-05 01:01:34 -0600 (Sun, 05 Jul 2009) | 2 lines Use uintptr_t rather than unsigned here for 64-bit correctness. r195356 | imp | 2009-07-05 01:00:51 -0600 (Sun, 05 Jul 2009) | 6 lines Define __ELF_WORD_SIZE appropriately for n64. Note for N32 I believe this is correct. While registers are 64-bit, n32 is a 32-bit ABI and lives in a 32-bit world (with explicit 64-bit registers, however). Change an 8, which was 4 + 4 or sizeof(int) + SZREG to be a simple '4 + SZREG' to reflect the actual offset of the structure in question. r195355 | imp | 2009-07-05 00:56:51 -0600 (Sun, 05 Jul 2009) | 7 lines (1) Use uintptr_t in preference to unsigned.

These expressions can be addresses or numbers, and that's a intptr_t if I ever saw one. r195351 | imp | 2009-07-05 00:43:01 -0600 (Sun, 05 Jul 2009) | 4 lines Define COP0_SYNC for SB1 CPU.

Provide n32/n64 register name defintions. This should have no effect for the O32 builds that everybody else uses, but should help make N64 builds possible (lots of other changes are needed for that).
