d177c19903 bwn(4): migrate bwn(4) to the native bhnd(9) interface, and drop siba_bwn.
- Remove the shim interface that allowed bwn(4) to use either siba_bwn or
  bhnd(4), replacing all siba_bwn calls with their bhnd(4) bus equivalents.
- Drop the legay, now-unused siba_bwn bus driver.
- Clean up bhnd(4) board flag defines referenced by bwn(4).

Uses of mallocarray(9).

The use of mallocarray(9) has rocketed the required swap to build FreeBSD.
This is likely caused by the allocation size attributes which put extra pressure
on the compiler.

Given that most of these checks are superfluous we have to choose better
where to use mallocarray(9). We still have more uses of mallocarray(9) but
hopefully this is enough to bring swap usage to a reasonable level.

0cee6dcdb0 misc geom and gnu: make some use of mallocarray(9).
Focus on code where we are doing multiplications within malloc(9). None of
these ire likely to overflow, however the change is still useful as some
static checkers can benefit from the allocation attributes we use for
mallocarray.

This initial sweep only covers malloc(9) calls with M_NOWAIT. No good
reason but I started doing the changes before r327796 and at that time it
was convenient to make sure the sorrounding code could handle NULL values.

8d14ca9c99 Introduce bwn(4) support for the bhnd(4) bus.
Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).

The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.

This diff introduces opt-in bwn(4) support for bhnd(4) by providing:

 - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
   bhnd(4) instead of siba_bwn(4).
 - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
   probes at a higher priority than the siba_bwn(4) PCI driver.
 - A set of compatibility shims that perform translation of bwn(4)'s
   siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
   is attached via a bhnd(4) bus parent. When bwn(4) is attached via
   siba_bwn(4), all siba_bwn function calls are simply passed through to
   their original implementations.

To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):

  hw.bwn_pci.preferred="1"

  if_bwn_pci_load="YES
  bwn_v4_ucode_load="YES"
  bwn_v4_lp_ucode_load="YES"

To verify that bwn(4) is using bhnd(4), you can check dmesg:

  bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0

... or devinfo(8):

pcib2
  pci2
    bwn_pci0
      bhndb0
        bhnd0
          bwn0
          ...

bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently
supported by bwn(4), including:

  - BCM4312
  - BCM4318
  - BCM4321

With minimal changes to the DMA code (not included in this commit), I was
also able to test support for newer BCMA devices by bringing up basic
working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets:

  - BCM43224
  - BCM43225

dbf8e132e1 [bwn] add initial bwn(4) N-PHY code, ported from Linux b43.
This is a GPLv2 PHY-N implementation based on the Linux b43 driver,
ported over to work in bwn(4).

I've tested this on the BCM4321 11abgn device, in 11bg and 11a modes.
The b43 PHY code only supports 11abg, no 11n, and 20MHz only wide
channels.

Yes, this is a GPLv2 driver, so it won't be included in the
default builds.

Tested:

* BCM4321 11abgn device (Apple!), 11bg and 11a STA mode.

179f14534e Import LEDE dts files for Ralink/Mediatek
This is an import of the reworked LEDE dts files. Besides other things
they make it easier for us to reuse.

The only diffs left are for the following SoCs:
MT7620A (fbsd-mt7620a.dtsi)
MT7621 (fbsd-mt7621.dtsi)
MT7628 (fbsd-mt7628an.dtsi)
RT3883 (fbsd-rt3883.dtsi)

So we include the fbsd-*.dtsi files at the end of the original LEDE dtsi
files, using '#include "fbsd-xxxx.dtsi"'.
For example, for MT7621, the LEDE dtsi file is mt7621.dtsi. At the end of
it we add:
#include "fbsd-mt7621.dtsi"
