* Finish new ARP (struct ethercom) changes.
Some references to sc_ac were left danglnig.
* Include if_dl.h and if_media.h.
* Delint printf() messages: int vs. long , int vs. pointer.
* Delete unused variables.
* add prototypes to <dma.h> for the per-device dma-setup functions.
* MachEmptyWriteBuffer() -> wbflush(). Also #include <bus.h>,
so that wbflush() expants to the locore callback vector entrypoint.
* rewrite findroot() based on NetBSD 1.2F i386 findoot().
* Rewrite makebootdev() to use struct devnametodevmaj pica_nam2blk[].
Previous changes changed the `devname' char array and findroot()
bot not makebootdev().
* Add prototypes, delint for gcc -Wall.
* Move declaration of locore communcation variables (CPU family,
cache sizes, etc) to mips/include/locore.h. Delete from
pmax/include/cpu.h and older versions from pica/include/cpu.h.
* Move definitions of CLKF_BASEPRI, CLKF_USERMODE to mips/include/cpu.
* Delete duplicate definitions in pica/include/cpu.h, pmax/include/cpu.h.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.
* use mips_round_page,mips_trunc_seg() instead of
pica_round_page(),pica_trunc_page().
* discard (unused) return value from TLBUpdate(), and delete
(unused) temporary variable used to hold it.
* Move mips-I pte (TLBlo) definitions from pmax/include/pte.h
to mips/include/mips1_pte.h
* Move mips-III pte (TLBlo) definitions from pica/include/pte.h
to mips/include/mips3_pte.h
* Add new mips/include/pte.h, which includes exactly one of
mips1_pte.h or mips3_pte.h (which still have namespace collisions),
depending on "options MIPS1" or "options MIPS3". (hack).
Move soft kvtopte(), ptetovk() definitions to mips/include/pte.h
* Add macro PTE_TO_PADDR() to hide the different hardware TLB formats
when mapping from pte to physical address.
* Add macro PTE_READONLY() to hide lack of SW read-only bit in mips-III
tlb. (mips1 pmap uses a sw bit in the PTE, mips3 looks up RO bit in
the kernel pmap.)
* Use macros (not direct TLB frobbing) in mips/trap.c, to make it
mips-1/mips-III indepenndet.
* Change {pmax,pica}/include/pte.h to just do #include <mips/pte.h>.
* fold in netBSD style changes:
``if (foo = bar)'' -> ``if ((foo = bar) != 0)''
* add mips1 vector as well as mips3 vector
* change vector names to make mips1 and mips3 locore entrpoints distinct
* add pmax additions (e.g., old fixes to ktrace code, kernel-TLB_miss
instrumentation)
* update stack traceback code to a newer version of the pmax code.
from arch/mips/mips/locore.S to arch/pmax/pmax/locore_machdep.S.
* Move ARC-specific locore code (vmstat -i counters) to
arch/pica/pica/locore_machdep.S.
* When the mips3 locore support is known to work, both ports can now use
arch/mips/mips/locore.S.
consistency with the way machdep headers for other things are done.
(the creation of the ecoff_machdep.h files was done on the CVS server, to
keep the RCS logs intact.)
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
