- Build an ECOFF version of the bootloader as "boot". As a temporary
measure (due to a bug in libbfd which has not yet been fixed, but
for which a work-around exists as a patch), install and ELF version
of the bootload as well as "boot.elf". "boot.elf" will go away once
the toolchain issue is resolved.
info along to the kernel (currently just the symbol table info).
- Don't bother with the startprog dance; we don't need to do anything
special, here, so just call the entry point directly.
- A bunch of random cleanup.
save off DDB symbol table information.
- Make loading of memory work reliably with the bootloader; for each
candidate memory type from ARCS (which now includes LoadedProgram),
check to see if the kernel is within that chunk, and load the pages
around it if it is.
- It's perfectly legal to have an 8 byte volume filename; the trailing
NUL is not required in this case.
- Default the partition type to "4.2BSD", not "EFS".
the parent, so we don't need to look at the innards of bus_dma anymore.
Also, remove the Todo item pertaining to autoconfig cleanup from the list
in the comments.
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h
- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup
DMA register offsets, as well as IRQ, to children. Use direct

* Add support for the second SCSI controller on the Indigo2.
the controller/SCSI bus.
* Implement controller/SCSI bus reset on SGI HPC3 SCSI using the
"channel reset" bit in the SCSI DMA channel control register.
the platform supplies a clkread function that does something other than
return 0 (which is the default unless overridden by the platorm code).
Supply such a function for the IP22; even if it isn't perfect, it goes
a long way to making ntp usable.
While I'm at it, move the ticks-per-hz variable out of the struct platform
since it's really private to the per-platform interrupt/clock code.
XXX: No clkread function supplied for IP32, since it has other problems --
like a hardcoded ticks-per-hz, but the same code as on the IP22 could be
used.
due to its similarities.
Patch has been tested by many people on the sgimips list for some time with
no complaints.

- Full support for SCSI-2 Tagged commands (enabled by default)
- Implement save and restore datapointer messages
- Formalize interface between MI and MD drivers.
- decouple interface between MD driver and DMA routines
- Use scsipi layer where appropriate (Tags, Sync Negotiations etc)
- control blocks stored using kernel pool(9) functions
- evcnt(9) compliant counters
- Enable advanced features on later WD33c93 chips.
(Identify message out phase is hardware assisted)
- Improved timeout support (one per active control block)
- Improved MESG_IN and MESG_OUT handling
- Start to tidy up debugging output
- Numerous bug fixes and cleanups throughout
Changes are based largely on the NCR53c9x MI driver for ideas on
how to DTRT.
string, if present, will override the second argument (which may be the
path/kernel being loaded). This will provide a way to netboot the kernel
and allow the root device be set to a disk partition.
