 1.15  02-Nov-2021  ryo In order to prevent _mcount() from being recursively called when built with COPTS=-O0,
sprinkle `__always_inline' to make _mcount() be generated as a single function.
 1.14  06-Apr-2010  nonaka Added support following boards.
- AlphaNet MS104-SH4
- TAC T-SH7706LAN Ver.3
- TAC T-SH7706LSR Ver.1
 1.13  28-Apr-2008  martin branches: 1.13.20; 1.13.22;
Remove clause 3 and 4 from TNF licenses
 1.12  03-Dec-2007  ad branches: 1.12.14; 1.12.16; 1.12.18;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
 1.11  16-Feb-2007  ad branches: 1.11.6; 1.11.22; 1.11.24; 1.11.30;
Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts
via a soft interrupt. In the near future, softclock will be run from process
context.
 1.10  09-Feb-2007  ad Merge newlock2 to head.
 1.9  21-Dec-2006  yamt merge yamt-splraiseipl branch.

- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
 1.8  27-Nov-2005  yamt branches: 1.8.20; 1.8.22;
implement splraiseipl() for the following ports.
evbppc, evbmips, evbsh3, hp700, mac68k, vax, x68k.
 1.7  22-Apr-2002  msaitoh branches: 1.7.6; 1.7.12; 1.7.28; 1.7.36;
increase _INTR_N from 7 to 11 (count both SCI and SCIF)
 1.6  24-Mar-2002  uch adapted to new interrupt code and shb changes.
 1.5  22-Feb-2002  uch branches: 1.5.4;
New NetBSD/sh3 clock framework.
+ hardclock source is moved from TMU1 to TMU0.
+ SH3/SH4 common kernel support.
+ PCLOCK estimation.
+ remove duplicated code.
 1.4  31-Oct-2000  msaitoh branches: 1.4.4;
add interrupt mode into wdog

To use:

ioctl(fd, SIOWDOGSETMODE, &val)

val: WDOGM_RESET -> reset when counter expired
WDOGM_INTR -> print PC when counter expired (new!)

This interface is still under experimental.
 1.3  13-Apr-2000  msaitoh move the Interrput Priority Level (IPL_*) definitions into MD part.
 1.2  24-Feb-2000  msaitoh multiple interrputs!!!
 1.1  13-Sep-1999  itojun branches: 1.1.2;
Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
 1.1.2.2  22-Nov-2000  bouyer Sync with HEAD.
 1.1.2.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
