inevitable component in Sun Exx00 machines and provides serial ports,
NVRAM and TOD amongst others which are handled by uart(4) and eeprom(4)
respectively). This driver currently only prints out information about
the chassis on attach and allows to blink the 'Cycling' LED (which is
duplicated on the front panel) of the clock board just like fhc(4) does
for the other boards. The device name for the LED is /dev/led/clockboard.

bus_generic_rl_release_resource() for the bus_release_resource() method
instead of a local copy.
- Correctly handle pass-through allocations in fhc_alloc_resource().
- In case the board model can't be determined just print "unknown model"
so the physical slot number is reported in any case.
- Add support for blinking the 'Cycling' LED of boards on a fhc(4) hanging
of off the nexus (i.e. all boards except the clock board) via led(4).
All boards have at least 3 controllable status LEDs, 'Power', 'Failure'
and 'Cycling'. While the 'Cycling' LED is suitable for signaling from
the OS the others are better off being controlled by the firmware.
The device name for the 'Cycling' LED of each board is /dev/led/boardX
where X is the physical slot number of the board. [1]

This is mentioned in the Handbook but it is not as obvious to new
users why bpf is needed compared to the other largely self-explanatory
items in GENERIC.

last in the list rather than first.
This makes the resouces print in the 4.x order rather than the 5.x order
(eg fdc0 at 0x3f0-0x3f5,0x3f7 is 4.x, but 0x3f7,0x3f0-0x3f5 is 5.x). This
also means that the pci code will once again print the resources in BAR
ascending order.
w/o problems than I was before... This simply brings back the knote_delete
as knlist_delete which will also drop the knote's, instead of just clearing
the list and seeing _ONESHOT...
Fix a race where if a note was _INFLUX and _DETACHED, it could end up being
modified... whoopse..

system have been attached, but no later. This ensures that we do
not explore ohci or uhci busses before the companion echi controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.
Some further changes are needed on architectures that do not currently
allow hooks to be inserted before configure_final() - alpha, ia64,
powerpc and sparc64. On these architectures the exploration will
now be delayed until the usb kthread runs.

currently copy the entire packet a couple bytes to get the packet aligned
properly...

in the window between the beginning of panic() and entering the debugger,
it's possible to receive interrupts. If we receive an interrupt, don't
preempt if panicstr != NULL, as the system is in the process of failing, and
the preempting thread is likely to stumble over the failure. The typical
scenario is during the printf() in panic() prior to entering the debugger,
but when running with a slower console type such as serial console.
It could be that the panic string should be passed to the debugger to print,
so that it can run from the debugger's environment rather than a regular
kernel printf.

Do our best to plug some memory leaks (VPD data, jumbo memory buffer,...).
Log if we cannot free because memory still in use[1].
Change locking to avoid ''acquiring duplicate lock of same
type: "network driver"'' and potential deadlock. Also seems to fix LOR #063.
[1] This change does not solve problems if buffers are still in use when
unloading if_sk.ko. There is ongoing work which will address jumbogram
allocations in a more general way.
