In case ELF Tool Chain's elfcopy introduces any regressions this knob is
available as a transition aid. It will be removed once we are confident
that any regressions have been fixed.
Update openresolve to version 3.7.3 including:
* Save the initial working directory and change to it just before
running any scripts.
This avoids scripts putting files accidently where they shouldn't.
* Strip trailing dot from search and domain names.
* man page improvements.

Use u_long instead of uint32_t variables to avoid overflow

(32 and 64-bit, LE and BE).
The changes were tested with QEMU's 'mips' target.
Most of the implementation was lifted from the ARM version, the appropriate
MIPS-specific things were implemented.
With these changes I am able to go all the way through the u-boot->ubldr->kernel
boot chain in QEMU on all combinations of bit-ness and endian-ness.
For the tests I've used FAT32 disk images (as FAT32 is supported by U-boot),
which include /boot/kernel/kernel and /boot/kernel/ubldr.bin
In U-boot I do:
fatload ide 0 <LOAD_ADDR> /boot/kernel/ubldr.bin; go <LOAD_ADDR>
where LOAD_ADDR is 80800000 for 32-bit and ffffffff80800000 for 64-bit
Then it's the usual ubldr that takes over and loads and starts a kernel.

ubldr.
The changes are mostly dealing with removing unnecessary casts from the U-Boot
API (we're passing only pointers, no obvious reason to cast them to uint32_t),
cleaning up some compiler warnings and using the proper printf format
specifiers in order to be able to compile cleanly for both 32-bit and 64-bit
MIPS targets.

Unlike buf_ring_peek, it only supports single consumer mode, and it
clears the cons_head if DEBUG_BUFRING/INVARIANTS is defined.
The normal use case of drbr_peek for network drivers is:
m = drbr_peek(br);
err = hw_spec_encap(&m); /* could m_defrag/m_collapse */
(*)
if (err) {
if (m == NULL)
drbr_advance(br);
else
drbr_putback(br, m);
/* break the loop */
}
drbr_advance(br);
The race is:
If hw_spec_encap() m_defrag or m_collapse the mbuf, i.e. the old mbuf
was freed, or like the Hyper-V's network driver, that transmission-
done does not even require the TX lock; then on the other CPU at the
(*) time, the freed mbuf could be recycled and being drbr_enqueue even
before the current CPU had the chance to call drbr_{advance,putback}.
This triggers a panic in drbr_enqueue duplicated element check, if
DEBUG_BUFRING/INVARIANTS is defined.
Use buf_ring_peek_clear_sc() in drbr_peek() to fix the above race.
This change is a NO-OP, if neither DEBUG_BUFRING nor INVARIANTS are
defined.

Freescale's QorIQ line includes a new ethernet controller, based on their
Datapath Acceleration Architecture (DPAA). This uses a combination of a Frame
manager, Buffer manager, and Queue manager to improve performance across all
interfaces by being able to pass data directly between hardware acceleration
interfaces.
As part of this import, Freescale's Netcomm Software (ncsw) driver is imported.
This was an attempt by Freescale to create an OS-agnostic sub-driver for
managing the hardware, using shims to interface to the OS-specific APIs. This
work was abandoned, and Freescale's primary work is in the Linux driver (dual
BSD/GPL license). Hence, this was imported directly to sys/contrib, rather than
going through the vendor area. Going forward, FreeBSD-specific changes may be
made to the ncsw code, diverging from the upstream in potentially incompatible
ways. An alternative could be to import the Linux driver itself, using the
linuxKPI layer, as that would maintain parity with the vendor-maintained driver.
However, the Linux driver has not been evaluated for reliability yet, and may
have issues with the import, whereas the ncsw-based driver in this commit was
completed by Semihalf 4 years ago, and is very stable.
Other SoC modules based on DPAA, which could be added in the future:
* Security and Encryption engine (SEC4.x, SEC5.x)
* RAID engine
Additional work to be done:
* Implement polling mode
* Test vlan support
* Add support for the Pattern Matching Engine, which can do regular expression
matching on packets.
This driver has been tested on the P5020 QorIQ SoC. Others listed in the
dtsec(4) manual page are expected to work as the same DPAA engine is included in
all.

So, this is the beginning of abstracting out the stats API calls

Summary:
Some drivers need special memory requirements. X86 solves this with a
pmap_change_attr() API, which DRM uses for changing the mapping of the GART and
other memory regions. Implement the same function for PowerPC. AIM currently
does not need this, but will in the future for DRM, so a default is added for
that, for business as usual. Book-E has some drivers coming down that do
require non-default memory coherency. In this case, the Datapath Acceleration
Architecture (DPAA) based ethernet controller has 2 regions for the buffer
portals: cache-inhibited, and cache-enabled. By default, device memory is
cache-inhibited. If the cache-enabled memory regions are mapped
cache-inhibited, an alignment exception is thrown on access.
Test Plan:
Tested with a new driver to be added after this (DPAA dTSEC ethernet driver).
No alignment exceptions thrown, driver works as expected with this.
