Note that you need at least xf86-video-intel 2.4.3 for this to work.
The G4X doesn't put the GATT into the same area of stolen memory
as all the other chips and older versions of the driver didn't
handle that properly.

o check feature bits when probing NPE ethernet support
o move firmware loading logic from if_npe to core npe support
o allow multiple refs to core NPE driver
o while here fix hw.npe.debug tunable path
o add definitions for more bits, for masking out IXP465-specific bits,
and %b format string
o add ixp4xx_read_feature_bits to retrieve the mask of valid features
(aka fuse bits)
o add cpu_is_ixp42x() macro
o print feature bits at boot
o add EHCI_SCFLG_BIGEMMIO flag to force big-endian byte-select to be
set in USBMODE
o split reset work into new public routine ehci_reset so bus shim drivers
can force big-endian byte-select before ehci_init
long commands into multiple requests. [08:12]
Avoid calling uninitialized function pointers in protocol switch
code. [08:13]

mac_proc_vm_revoke_recurse() requests a read lock on the vm map at the start
but does not handle failure by vm_map_lock_upgrade() when it seeks to modify
the vm map. At present, this works because all lock request on a vm map are
implemented as exclusive locks. Thus, vm_map_lock_upgrade() is a no-op that
always reports success. However, that is about to change, and
proc_vm_revoke_recurse() will require substantial modifications to handle
vm_map_lock_upgrade() failures. For the time being, I am changing
mac_proc_vm_revoke_recurse() to request a write lock on the vm map at the
start.

firmware versions which wedge when using the OFW test service,
so given that we don't really depend on SUNW,stop-self just nuke
it altogether instead of risking problems.
- At least Fire V880 have a small hardware glitch which causes the
reception of IDR_NACKs for CPUs we actually haven't tried to send
an IPI to, even not as part of the initial try. According to tests
this apparently can be safely ignored though, so just return if
checking for the individual IDR_NACKs indicates no outstanding
dispatch. Serializing the sending of IPIs between MD and MI code
by the combined usage of smp_ipi_mtx makes no difference to this
phenomenon. [1]
- Provide relevant debugging bits already with the initial panic
in case of problems with the IPI dispatch, which would have
allowed to diagnose the above problem without a specially built
kernel.
- In case of cheetah_ipi_selected() base the delay we wait for
other CPUs which also might want to dispatch IPIs on the total
amount of CPUs instead of just the number of CPUs we let this
CPU send IPIs to because in the worst case all CPUs also want
to IPI us at the same time.

In r185891 I removed the newlines from messages written to /dev/console,
because it made startup messages from rc-scripts harder to read. This,
unfortunately, causes the kernel message that is printed after a
non-terminated log message to be concatenated.
This could be fixed, but on short term it's better to just revert the
change.

Inside ptsdrv_{in,out}wakeup() we call KNOTE_LOCKED() to wake up any
kevent(2) users. Because the kqueue handlers are executed synchronously,
we must set PTS_FINISHED before calling ptsdrv_{in,out}wakeup().

Right now the wchan strings "ttyinp" and "ttybgw" only differ one
character from the strings we used prior to MPSAFE TTY. Just rename them
back to their pre-MPSAFE TTY counterparts.
Also rename "ttylck" to "ttymtx", which should make it more clear that a
process is blocked on the TTY mutex, not some other form of locking.
o add support for IXP435 cpu's (e.g. 64 irq's)
o add support for Cambria-specific devices: npe, led's (front panel and
octal latch), ehci, mcu, ide cf
o redo memory mapping for xscale/ixp4xx boards: previously memory
was assumed aliased to 0x10000000 but this appears to be true only
for ixp425 systems and breaks operation on others; rework so memory
is assumed to start at 0
o rework NPE configuration support to use NPE id's instead of port #'s;
these changes also rename the associated MAC's to follow the NPE's
they are attached to
o update npe firmware to latest rev (same license) and update default fw
imageid's to match; in particular this adds NPE-A and crypto support
o re-style NPE fw handling code and add a console msg identifying the
attributes of the loaded fw
o fix numerous problems with handling failures during npe setup
o fix npe rx q setup; need to spin waiting for mailbox responses during
early boot stages as qmgr interrupts are not delivered; this fixes
the problem where all 8 traffic classifications were not tied to the
rx q (and eliminates the console msg "remember to fix rx q setup")
o add DELAY to npe MII wait logic for IXP435
o strip down builtin phys->virt address translation table in resource
handling to just those resources that require it and add a console msg
to alert people when this (kludge) table needs to be extended
o purge a bunch of dead netbsd-ism's
o cleanup avila led driver
o add Cambria support to boot2 and rework code for better multi-board support
Notes:
1. NPE-A doesn't work and causes NPE-C to stop working; it is disabled
in the hints
2. USB isn't working yet; controller communicates ok but device
discovery fails
3. Cambria support must be configured separately from IXP425 boards;
multi-board support is TBD
