If we fail noise floor calibration then we may end up with a deaf NIC

Earlier chips seem to get less stuck in this condition versus AR9280/later

return NF calibration failures.
This HAL routine would only return failure if the channel was not configured.
This is a no-op until the driver side code for doing resets and the HAL

The upstream repository is on github BLAKE2/libb2. Files landed in
sys/contrib/libb2 are the unmodified upstream files, except for one
difference: secure_zero_memory's contents have been replaced with
explicit_bzero() only because the previous implementation broke powerpc
link. Preferential use of explicit_bzero() is in progress upstream, so
it is anticipated we will be able to drop this diff in the future.
sys/crypto/blake2 contains the source files needed to port libb2 to our
build system, a wrapped (limited) variant of the algorithm to match the API
of our auth_transform softcrypto abstraction, incorporation into the Open
Crypto Framework (OCF) cryptosoft(4) driver, as well as an x86 SSE/AVX
accelerated OCF driver, blake2(4).
Optimized variants of blake2 are compiled for a number of x86 machines
(anything from SSE2 to AVX + XOP). On those machines, FPU context will need
to be explicitly saved before using blake2(4)-provided algorithms directly.
Use via cryptodev / OCF saves FPU state automatically, and use via the
auth_transform softcrypto abstraction does not use FPU.
The intent of the OCF driver is mostly to enable testing in userspace via
/dev/crypto. ATF tests are added with published KAT test vectors to
validate correctness.

libfdt highlights since 1.4.3:
- fdt_property_placeholder added to create a property without specifying its

- stringlist helper functions added to libfdt
- Improved overlay support
- Various internal cleanup
Also switch stand/fdt over to using libfdt for overlay support with this
update. Our current overlay implementation works only for limited use cases
with overlays generated only by some specific versions of our dtc(1). Swap
it out for the libfdt implementation, which supports any properly generated

This will be followed up fairly soon with an update to dtc(1) in tree to
properly generate overlays.
MFC note: the <stdlib.h> include this update introduces in libfdt_env.h is
apparently not necessary in the context we use this in. It's not immediately
clear to me the motivation for it being introduced, but it came in with
overlay support. I've left it in for the sake of accuracy and because it's

Compared to the previous version, v0.16, there are a couple of minor
changes:
- CLOUDABI_AT_PID: Process identifiers for CloudABI processes.
Initially, BSD process identifiers weren't exposed inside the runtime,
due to them being pretty much useless inside of a cluster computing
environment. When jobs are scheduled across systems, the BSD process
number doesn't act as an identifier. Even on individual systems they
may recycle relatively quickly.
With this change, the kernel will now generate a UUIDv4 when executing
a process. These UUIDs can be obtained within the process using
program_getpid(). Right now, FreeBSD will not attempt to store this
value. This should of course happen at some point in time, so that it
may be printed by administration tools.
- Removal of some unused structure members for polling.
With the polling framework being simplified/redesigned, it turns out
some of the structure fields were not used by the C library. We can
remove these to keep things nice and tidy.

Rework the dTSEC and FMan drivers to be more like a full bus relationship,
so that dtsec can use bus_alloc_resource() instead of trying to handle the
offset from the dts. This required taking some code from the sparc64 ebus
driver to allow subdividing the fman region for the dTSEC devices.
This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is
currently not working, and ARM support has not been completed or tested on the

In rS323851, some casts were adjusted in calls to nvlist_next() and
nvlist_get_pararr() in order to make scan-build happy. I think these changes
just confused scan-build into not reporting the strict-aliasing violation.
For example, nvlist_xdescriptors() is causing nvlist_next() to write to its
local variable nvp of type nvpair_t * using the lvalue *cookiep of type
void *, which is not allowed. Given the APIs of nvlist_next(),
nvlist_get_parent() and nvlist_get_pararr(), one possible fix is to create a
local void *cookie in nvlist_xdescriptors() and other places, and to convert
the value to nvpair_t * when necessary. This patch implements that fix.

The most important change in this release is the removal of the
poll_fd() system call; CloudABI's equivalent of kevent(). Though I think
that kqueue is a lot saner than many of its alternatives, our
experience is that emulating this system call on other systems
accurately isn't easy. It has become a complex API, even though I'm not
convinced this complexity is needed. This is why we've decided to take a
different approach, by looking one layer up.
We're currently adding an event loop to CloudABI's C library that is API
compatible with libuv (except when incompatible with Capsicum).
Initially, this event loop will be built on top of plain inefficient
poll() calls. Only after this is finished, we'll work our way backwards
and design a new set of system calls to optimize it.
Interesting challenges will include integrating asynchronous I/O into
such a system call API. libuv currently doesn't aio(4) on Linux/BSD, due
to it being unreliable and having undesired semantics.
