* convert phy_getinfo() to take a "gmode" flag, rather than the siba
TGSHIGH flags and then check for 2GHz. This should ensure that
gmode is set correctly even on DUALPHY NICs.
* move the siba_powerup() call and the TGSHIGH decoding into a
call to bwn_is_bus_siba(), and return an error if it's called
on anything else. We don't yet do anything else, but when we do..
Tested:
* BCM4322, 11a STA
This is all for the bhnd(4) work in progress. It's enough to probe/attach
all the bhnd internals, but we're missing OTP support and some cleanup
code. And, well, all the rest of the bhnd(4) migration.
So no, this won't give you BCM43225 support. Sorry!
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.

The EFSYS_PREEMPT_DISABLE() and EFSYS_PREEMPT_ENABLE() macros
were used to ensure correct timing of I2C operations. The APIs
for I2C operations have been removed, so these macros have no
callers.

It does not belong to the vmbus.
While I'm here rework the Hypercall setup, e.g. use busdma(9)

The variable "size" stores number of words (4bytes). But the loop over
memory uses size as number of bytes to scan memory. As result it fetches
only 1/4th of memory.
This patch solves this problem and nvram2env fetches all NVRAM variables.
Test plan:
Pre-requisites: any MIPS board with ASCII-based NVRAM mapped into memory
* Add "device nvram2env" into kernel configuration
* Specify hints: base is mandatory (according to nvram2env(4))
hint.nvram.0.base=0x1c7f8000 (it's valid address for Asus RT-N53 with
flags = 0x4)
* Build & load kernel with bootverbose
Actual result: only part of nvram variables are found
Expected result: all variables are found

This adds a BHND_BUS_GET_ATTACH_TYPE(); the primary use-case is to let
chipc make a coarse-grained determination as to whether UART, SPI, etc
drivers ought to be attached, and on fullmac devices, whether a real
CPU driver ought to be skipped for the ARM core, etc.
Tested:
* BCM4331 (BHND)
* BCM4312 (SIBA)

Override global retry limit (which is set in R92C_RL) via per-frame
TX descriptor field. Obsoletes D3840 (should work better with 2+ vaps).
Tested with RTL8188EU and RTL8192CUS in STA mode (maxretry = [3-9]).
After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.
This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.

The GPIO hardware should not be owned by a single device, this defeats any
chance of use of the GPIO controller as an interrupt source.
ow(4) is now the only consumer of this 'feature' before we can remove it
for good.
