bhnd(4): Perform explicit chipc child enumeration.
Replaces use of DEVICE_IDENTIFY with explicit enumeration of chipc child devices using the chipc capability structure.
This is a precursor to PMU support, which requires more complex resource assignment handling than achievable with the static device name-based hints table.

bhnd(4): Fix resource allocation issues exposed by chipc PMU support.
- Delete all chipc children on attachment failure. - Added missing bhnd_nexus bhnd_bus_deactivate_resource implementation. - Drop a CHIPC_UNLOCK() accidentally left behind after lifting synchronization into the chipc region refcounting API. - Fix re-allocation of chipc resources. Previously, the resource ID was reset to -1 on release, preventing later re-allocation.

bhnd(4): support IPX OTP NVRAM/SPROM data source
Add support for fetching SPROM data from OTP on chipsets with an IPX OTP controller (including the BCM43225).
This integrates the NVRAM data source into the chipc_caps capability structure, and adds a sprom_offset field that can be used with OTP to locate the SPROM image data (found within the general use region, H/W subregion).
This also removes one of two duplicate parse error messages reported by both the bhnd_sprom driver and the underlying SPROM parsing API.

Fix several MIPS/BCM-blocking bugs in bhnd(4) chipc
- Correct IRQ lines for UART (to fix IRQ lookup in future) - Check device unit in resource assignment during chipc_add_child - If chipc hint->size is RM_MAX_END, resource end should be same as window end - Clear reference from resource list entry to resource in case of resource release - Add CHIPC_GET_CAPS implementation - Correct chipc flash constants (to be unshifted) - Default implementation of get_attach_type should iterate over device tree - Add default implementation for BHND_CHIPC_GET_CAPS usable by chipc grandchildren

[bhnd] Fix release of uninitialized SPROM shadow in chipc detach.
This was triggering a panic on detach; the SPROM shadow is now maintained by the bhnd_sprom_chipc driver, and should be removed from chipc.

[bhnd] Integrate bhnd_chipc's BUS_ADD_CHILD() with a child resource mapping table.
This adds support for automatically configuring bhnd_chipc bus children with associated resources, using an internal 'hints' table based directly on Michael Zhilin's chipc resource mapping work.
The bhnd_sprom_chipc driver has been converted to use DEVICE_IDENTIFY() with the new resource table.
This should be nearly drop-in compatible with the child device drivers in D6250.

[bhnd] Normalize bhnd(4) device matching API
This unifies handling of core, chip, and board-level device matching, and adds support for matching device drivers against the bus attach type (e.g. SoC vs WiFi adapter).
Core-level quirks on Broadcom's chipsets generally are specific to some combination of chip model, core revision, chip package (e.g. 12x9 SMT package), SROM revision, etc.
Unifying the match APIs for all three attribute types (core, chip, board/srom) allows defining a single device quirk table that matches across all of those attributes.

[bhnd] Implement pass-through resource management for ChipCommon.
This patchset adds support to bhnd_chipc for sharing SYS_RES_MEMORY resources with its children, allowing us to hang devices off of bhnd_chipc that rely on access to a subset of the device register space that bhnd_chipc itself must also allocate.
We could avoid most of this heavy lifting if RF_SHAREABLE+SYS_RES_MEMORY wasn't limited to use with allocations at the same size/offset.
As a work-around, I implemented something similar to vga_pci.c, which implements similar reference counting of of PCI BAR resources for its children.
With these changes, chipc will use reference counting of SYS_RES_MEMORY allocation/activation requests, to decide when to allocate/activate/ deactivate/release resources from the parent bhnd(4) bus.
The requesting child device is allocated a new resource from chipc's rman, pointing to (possibly a subregion of) the refcounted bhnd resources allocated by chipc.
Other resource types are just passed directly to the parent bhnd bus; RF_SHAREABLE works just fine with IRQs.
I also lifted the SPROM device code out into a common driver, since this now allows me to hang simple subclasses off of a common driver off of both bhndb_pci and bhnd_chipc.
Tested:
* (landonf) Tested against BCM4331 and BCM4312, confirmed that SPROM still attaches and can be queried.

[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.

[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.

[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.

[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.

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!
