This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.
Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.
Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive. The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.
o) The MAC set must occur before the multicast list is set up as the former
will enable the CAM unconditionally, while promiscuous mode disables it,
so if promiscuous mode is to be set this must occur after the MAC is
programmed.
o) The multicast list must be set up unconditionally as even if flags have
not changed, if the interface has gone through a reinitialization, the
state of the CAM as changed by the MAC initialization could be incorrect.
o) Call octm_init when flags change, even if the interface is already running.
handle address, where we're using handles as raw addresses.
This fixes devices with subregions on Octeon PCI specifically, and likely also on
MIPS more generally, where there isn't another bus_space in use that was doing the
math already.

octeon_ap_boot is not a bitmask. It holds the CPU Id of the
AP currently being started. As such there's no need to make
it a 64-bit integral and we're not limited to 64 CPUs.

signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage
as appropriate.
- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.

XXX jeff@ suggests that all_cpus should include cores that are offline or
running other applications/OSes, so the platform API should be further
extended to allow us to set all_cpus to include all cores that are
