The original intention was to put devskel in to the
kernel to detach what it provides from devsrv.
That is not a good reason, just move it to userspace.
auth/box has been changed to exec skelfs instead
of relying on '#z'.

some more thoughts on this, i think as 0x15*2 is not multiple
of 8, fw rounds the offset to 0x14*2. i have touched to code
to read data from 0x14*2 then ignore the first 2 bytes, just
so it's not confusing. if this causes mac to be read wrong again,
report.
also, some more changes:
1. set the fwname at iwlpci, just to align the behavior with 8000+.
this is a cosmetic change.
2. i have discovered that on device boot/reset/shutdown functions,
our driver slept way much more than it should. the reason for that is,
driver used the function delay() on places where it needs to use
microdelay() instead. i have modified the code to use microdelay().
wpi likely needs similar changes too. i hope that this does not
break the code.
3. zzz a bit more on tx/rx scheduler shutdowns and niclock.
4. openbsd's iwm and linux apparently does not check if ownership
was obtained anymore in their handover functions. instead they
just loop until the hw is ready. aligned the behavior.
see linux commit: 289e5501c3141191dd830957f1d764d3dc14a54f
5. don't take antenna masks from nvm. it's apparently empty
in some cards from 7k family. we will rely on what the fw file gives
us.
6. when the calibration is completed, wakeup the proc that runs
postboot. otherwise that thing sleeps for like 2 whole seconds
even if calibration completed earlier.
i honestly don't think any of these changes will fix 7260 not
being able to get calibration results, but i don't see anything
wrong at all in postboot7000 at this point. i will just hope
these changes somehow make it get calibration results.

To avoid a MAXMACH limit of 32 and make
txtflush into an array for the bitmap.
Provide portable macros for testing and clearing
the bits: needtxtflush(), donetxtflush().
On pc/pc64, define inittxtflush()/settxtflush()
as no-op macros, avoiding the storage overhead of
the txtflush array alltogether.
SSL is implemented by devssl. It's extremely
obsolete by now, and is not used anywhere but
cpu, import, and oexportfs.
This change strips out the devssl bits, but
does not (yet) remove the code from libsec.
This makes vmap()/vunmap() take a vlong size argument,
and change the type of Pci.mem[].size to vlong as well.
Even if vmap() wont support large mappings, it is nice to
get the original unruncated value for error checking.
pc64 needs a bigger VMAP window, as system76 pangolin
puts the framebuffer at a physical address > 512GB.

The new interface uses pci capability structures to locate the
registers in a rather fine granular way making it more complicated
as they can be located anywhere in any pci bar at any offset.
As far as i can see, qemu (6.0.50) never uses i/o bars in
non-legacy mode, so only mmio is implemented for now.
The previous virtio drivers implemented the legacy interface only
which uses i/o ports for all register accesses. This is still
the preferred method (and also qemu default) as it is easier to
emulate and most likely faster.
However, some vps providers like vultr force the legacy interface
to disabled with qemu -device option "disable-legacy=on" resulting
on a system without a disk and ethernet.
Remove unused fields and factor common fields into a
new PMach struct in port/portdat.h.
The fields machno, splpc and proc are not moved to
PMach as they are part of the known offsets from
assembly (l.s).
let pci.c deal with the special cardbus controller bar0 and
expansion roms.
handle apic interrupt routing for devices behind a cardbus slot.
do not free the pcidev on card removal, as the drivers
most certanly are not prepared to handle this yet.
instead, we provide a pcidevfree() function that just unlinks
the device from pcilist and the parent bridge.
This adds the new function pointer PCArch.clockinit(),
which is a timer dependent initialization routine.
It also takes over the job of guesscpuhz(). This way, the
architecture ident code can switch between different
timers (i8253, HPET and XEN timer).
Revert the change, as it causes system lockups on bootup
on some systems with USB OHCI controllers, suspected to be
caused by BIOS/SMM accessing the device as BIOS handover
has not been executed yet.
We might bring that back when the problem has is better
understood.
