d9dbd70bca Update CFLAGS for clang compatibility
* Clang/llvm does not (yet) support -m(no-)spe, so make it gcc-only
* Clang now supports -msoft-float, and does not appear to recognize
  "-disable-ppc-float-in-variadic", which appears to have been a crutch until
  soft-float was implemented.  It's now implemented for both 32- and 64-bit.
* Clang/llvm use a 'medium' code model by default for powerpc64, supporting up
  to 4GB TOC, and does not support the '-mminimal-toc' option.  Given both of
  these, make -mminimal-toc gcc-only.

4691c88fee [mips] add some (temporary, I hope!) mips24k/mips74k hwpmc modules.
Ideally we'd have a top level hwpmc module with the shared bits, then
cpu specific glue as needed.  However, on the MIPS side, there's no
probe code - {mips24k, mips74k, octeon} implement a set of methods
that hwpmc_mips.c expects.

So this populates separate modules with duplicate code.
Ew, but it does work.

This gets me off the hook - these work fine as copied into the relevant
mfsroot for mips24k/mips74k systems.

TODO:

* do it the "right" way in the future.  Note that modules/hwpmc/ does
  build fine on MIPS, it jusn't DO anything.  So it'd be nice to
  maybe call that "hwpmc_core" and then "hwpmc" can be the CPU/arch glue.

f3e7afe2d7 Implement kernel support for hardware rate limited sockets.
- Add RATELIMIT kernel configuration keyword which must be set to
enable the new functionality.

- Add support for hardware driven, Receive Side Scaling, RSS aware, rate
limited sendqueues and expose the functionality through the already
established SO_MAX_PACING_RATE setsockopt(). The API support rates in
the range from 1 to 4Gbytes/s which are suitable for regular TCP and
UDP streams. The setsockopt(2) manual page has been updated.

- Add rate limit function callback API to "struct ifnet" which supports
the following operations: if_snd_tag_alloc(), if_snd_tag_modify(),
if_snd_tag_query() and if_snd_tag_free().

- Add support to ifconfig to view, set and clear the IFCAP_TXRTLMT
flag, which tells if a network driver supports rate limiting or not.

- This patch also adds support for rate limiting through VLAN and LAGG
intermediate network devices.

- How rate limiting works:

1) The userspace application calls setsockopt() after accepting or
making a new connection to set the rate which is then stored in the
socket structure in the kernel. Later on when packets are transmitted
a check is made in the transmit path for rate changes. A rate change
implies a non-blocking ifp->if_snd_tag_alloc() call will be made to the
destination network interface, which then sets up a custom sendqueue
with the given rate limitation parameter. A "struct m_snd_tag" pointer is
returned which serves as a "snd_tag" hint in the m_pkthdr for the
subsequently transmitted mbufs.

2) When the network driver sees the "m->m_pkthdr.snd_tag" different
from NULL, it will move the packets into a designated rate limited sendqueue
given by the snd_tag pointer. It is up to the individual drivers how the rate
limited traffic will be rate limited.

3) Route changes are detected by the NIC drivers in the ifp->if_transmit()
routine when the ifnet pointer in the incoming snd_tag mismatches the
one of the network interface. The network adapter frees the mbuf and
returns EAGAIN which causes the ip_output() to release and clear the send
tag. Upon next ip_output() a new "snd_tag" will be tried allocated.

4) When the PCB is detached the custom sendqueue will be released by a
non-blocking ifp->if_snd_tag_free() call to the currently bound network
interface.

d786719d90 [intelspi] Add SPI driver for Intel BayTrail SoC
Add SPI mode (PIO-only) support for Intel Synchronous Serial Port that
can be found in several Intel's products starting from PXA family.
Most of implementations have slight differences in behavior and in
addresses for registers subset. This driver covers only BayTrail SoC
implementation for it's the only hardware I have to test it on.

Driver attaches to ACPI bus only and does not have PCI or FDT support
for now due to lack of hardware to test it on.

"intelspi" is the best name I've managed to come up with. Linux driver
name (spi-pxa2xx) does not make sense because current implementation
does not support actual PXA2xx SoCs. And as far as I know there is no
codename assigned to Intel SSP chip.

- Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling
  higher-level NVRAM operations (indexed lookup, data conversion, etc) from
  the underlying NVRAM file format parsing/serialization.
- Implemented a new high-level bhnd_nvram_store API, providing indexed
  variable lookup, pending write tracking, etc on top of an arbitrary
  bhnd_nvram_data instance.
- Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store
  API.
- Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM
  variable values, including applying format-specific behavior when
  converting to/from the NVRAM string representations.
- Dropped the now unnecessary bhnd_nvram driver, and moved the
  broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom.
- Implemented a new nvram_map file format:
        - Variable definitions are now defined separately from the SPROM
          layout. This will also allow us to define CIS tuple NVRAM
          mappings referencing the common NVRAM variable definitions.
        - Variables can now be defined within arbitrary named groups.
        - Textual descriptions and help information can be defined inline
          for both variables and variable groups.
        - Implemented a new, compact encoding of SPROM image layout
          offsets.
- Source-level (but not build system) support for building the NVRAM file
  format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a
  userspace library.

The new compact SPROM image layout encoding is loosely modeled on Apple
dyld compressed LINKEDIT symbol binding opcodes; it provides a compact
state-machine encoding of the mapping between NVRAM variables and the SPROM
image offset, mask, and shift instructions necessary to decode or encode
the SPROM variable data.

The compact encoding reduces the size of the generated SPROM layout data
from roughly 60KB to 3KB. The sequential nature SPROM layout opcode tables
also simplify iteration of the SPROM variables, as it's no longer
neccessary to iterate the full NVRAM variable definition table, but
instead simply scan the SPROM revision's layout opcode table.
