8ef24a0d4b [bhnd] Finish bhnd(4) PCI/PCIe-G1 hostb support.
Now that we've got access to SPROM and can access board identification,
this implements all known remaining hardware work-arounds for the bhnd(4)
PCI and PCIe-G1 cores operating endpoint mode.

Additionally, this adds an initial set of skeleton PCIe-G2 hostb and pcib
drivers, required by fullmac and newer softmac devices.

d567592b68 [bhnd] Centralize fetching of board information
Centralizes fetching of board information (vendor, type, revision, etc),
and adds support for matching quirks against board identification info.

* Adds a BHND_BUS_READ_BOARD_INFO(), allowing bhnd bus/bus parent(s) to
  handle implementation-specific fetching of board info.
* Integrates board type constants from the latest Broadcom ISC-licensed
  bcmdevs.h included in dd-wrt's Broadcom driver source drops.
* Adds support for matching on chip/board quirks to bhnd_device_quirks()/
  bhnd_chip_quirks().
* Use the new board/chip quirk matching to match Apple devices that failed
  to set BFL2_PCIEWAR_OVR in SROM.

e83ce34035 [bhnd] Initial bhnd(4) SPROM/NVRAM support.
This adds support for the NVRAM handling and the basic SPROM
hardware used on siba(4) and bcma(4) devices, including:

* SPROM directly attached to the PCI core, accessible via PCI configuration
  space.
* SPROM attached to later ChipCommon cores.
* SPROM variables vended from the parent SoC bus (e.g. via a directly-attached
  flash device).

Additional improvements to the NVRAM/SPROM interface will
be required, but this changeset stands alone as working
checkpoint.

8a3fcfa7be [bhnd] Fix ChipCommon probing.
ChipCommon probing uses mapping table "chipc_devices". It calls bhnd_device_lookup,
which iterate over mapping table with end condition:

entry->desc != NULL

So if mapping table contains row with description equals to NULL, it will
stop processing of mapping. I.e. description is mandatory field and should
be not NULL.

This patch corrects mapping table for ChipCommon.

bb64eecc0b [bhnd] Add a common bhnd_pci driver shared by both bhnd_pcib and bhnd_pci_hostb
This extracts common code from bhndb_pci, bhnd_pcib, and bhnd_pci_hostb into a
simpler shared bhnd_pci base driver, and should enable SoC-side implementation
of bhnd_pcib root complex support.

36e4410ab0 [bhnd] Standardize bhnd device tables and quirk matching.
This add a bhnd device table mechanism that standardizes matching of
devices on the bhnd(4) bus, discovery of device quirk flags, and should
be pluggable into the new PNPINFO machinery.

4ad7e9b01a Bring over the initial rewrite of the broadcom bus support found in their
SoCs and various chips (including, famously, their wifi chips.)

This is "just" (all 20,000 lines of it) code to enumerate the various
versions of busses inside these devices, including the PCI bridge and
the direct SIBA bridge found in MIPS chips.

It also includes shared code for some bus operations (suspend, resume, etc);
EEPROM/SROM/etc parsing and other things that are shared between chips.

Eventually this'll replace the code that bwi/bwn uses for the internal
bus, as well as some apparently upcoming mips74k broadcom SoC support
which uses bwn!

Thanks to Landon Fuller <landonf@landonf.org> for all this work!
