try to locate it using the residual data. On some machines this doesn't
work, so we fall back to hardcoding it. This should fix isa interrupts
on the 7025-F40, which has the IVR at a different location.
out how to properly reboot these machines, instead we make use of the
auto-poweron-alarm time, and power cycle the machine to simulate a
reboot. This is a hack, but until I get documentation on these machines,
at least you will be able to reboot them.
for a magical PCI device location (that is sometimes wrong), we scan the
residual data for an MPIC, and if we find one, wire it up from there.
This will hopefully allow interrupts to work on the MPC750 and the
7025-F40. I suspect however the interrupt vector address on the 7025 will
still need some work.
1) Fix support for the powerstack E1. This machine needs to use the 8259
directly, and cannot use the prep interrupt vector register. Place a
quirk entry in the table for the machine.
2) Add a new com0_vreset boot image. The vreset code only works on a few
machines, and breaks others like the 7025-F40. Its only limitedly useful
when used with the com0, so just make it an optional image the user can
install by hand if they want.
3) Bump the bootloader to 1.8 with the above change.
2) Modify pnpbus attachment code to record the chipid of the device if it
has one.
3) Change the clock probes to use the chipid, rather than relying on
potentially untrustworthy subtype and interface.
4) Add decoding of memory ranges to the RESIDUAL_DUMP code.
5) Add a we@pnpbus device to allow netbooting and root device detection
from an IBM we ethernet. (it will only work if your firmware detects it)
6) Because I moved the pnpbus probe to occur prior to pci and isa, it
screwed up the root device detection and firmware path building code.
Completely rewrite the fw-path detection code to deal with this.
and INSTALL_SMALL. Since floppy images have to fit on one floppy, we
have to really cut down on the drivers on that image, but people
netbooting don't have that problem, so they deserve a more featured
kernel to install with. (namely one with raid support and more ethernet
drivers)
ntp on my 7248, however, my 7043-140 is still a bit flaky. I suspect the
only way to fix the 7043 is going to be writing a timecounter driver for
the 8254 present on these machines. Either way, this makes some of the
machines better, and the other machines are still about the same as they
were before, so it's a net gain for the port.
residual with the pnpbus probes, than it is to do it with raw isa probes,
so I've replaced the isa mkclock and mcclock code with a pnpbus attachment.
While writing the mkclock code, I realized that on motorola prep machines
the mkclock uses the same port range as the nvram part. (it's actually
the same chip/part). This was causing the nvram not to work on those
machines. Now the nvram code will recognize this, and wire up the
mkclock as well. The mkclock probe is just a stub probe used to
pre-detect the fact that this is one of those machines.
1) Rather than build an array of the pci->intr mappings, build a proplib
tree.
2) add a SIMPLEQ of device properties to the pci_chipset_tag to hold the
proplib trees of each bus.
3) Move the interrupt routing code from pci_conf_interrupt to pci_map_intr()
4) Deal properly with non-native PCI bridge chips that are not recognized
by the prep firmware, and therefore are not noted in the residual data.
The major win of this restructure is #4. Hopefully I haven't broken
anything. Tested on a 7248-100, 7043-140 and 7024-E20.

models. This code was made possible by assistance from Cory Bajus.
Add code that asks the PCI bridge what it's config base address is, and
use that when wiring up an indirect bridge type.
Move prep's user segment register to 10, because the 7025's PCI config
address is at 11, where the user segment used to be.
Add a battable entry for 0xbf800000 for machines with RS6K bridges.
There is still probably work left to be done before a 7025-F40 is fully
supported.
1) The E1 seems to have the int. siop wired to irq 14-level and the internal
wdc wired to irq 14-edge. special case and fail the wdc probe on E1's.
2) If we fail to map the NVRAM registers, return, rather than trying to talk
to them and panic'ing the box.
3) revert my previous "fix" to pnpbus to make irq's default to level. It
was wrong, and didn't even fix the powerstack.
With this, we have limited PowerStack E1 support. The machine cannot
talk to it's IDE controller, and cannot detect it's boot device
automatically, but it does come up and run. Tested with NFS root.
1) Rewrite vreset.c completely. Saves about 1k, and now it sets the
screen up much better. Previously the resulting video mode looked bad on
my CRT, and my LCD wouldn't even recognize it as a valid mode. Now it
looks reasonably good and my LCD can talk to it.
2) Call vga_reset unconditionally in the setup process to fix the onboard
VGA. If you have a VGA and use the serial console, this will allow you
to still use the VGA device for getty/wscons. Tested on a 7248 with VGA
and a 7043 without VGA.
3) Change filesystem.c to use nullfs rather than ufs and cd9660. We
don't actually need an fs at all, but it would take a major rewrite to
get rid of them completely. This saves about 6KB on the bootloader.
4) Bump version to 1.7.

this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
