# 302189 25-Jun-2016 landonf

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.

# 301411 04-Jun-2016 landonf

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.

# 301409 04-Jun-2016 landonf

bhnd(4): Add support for chipc-attached flash

This adds support for serial (via SPI) and parallel (via CFI) flash
as found on BCM47xx/BCM53xx SoCs.

# 301408 04-Jun-2016 landonf

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

# 300548 24-May-2016 adrian

[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.

# 300015 17-May-2016 adrian

[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.

# 296077 26-Feb-2016 adrian

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!
