Small summary
-------------
o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
option IPSEC_SUPPORT added. It enables support for loading
and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
support was removed. Added TCP/UDP checksum handling for
inbound packets that were decapsulated by transport mode SAs.
setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
build as part of ipsec.ko module (or with IPSEC kernel).
It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
methods. The only one header file <netipsec/ipsec_support.h>
should be included to declare all the needed things to work
with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
- now all security associations stored in the single SPI namespace,
and all SAs MUST have unique SPI.
- several hash tables added to speed up lookups in SADB.
- SADB now uses rmlock to protect access, and concurrent threads
can do SA lookups in the same time.
- many PF_KEY message handlers were reworked to reflect changes
in SADB.
- SADB_UPDATE message was extended to support new PF_KEY headers:
SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
avoid locking protection for ipsecrequest. Now we support
only limited number (4) of bundled SAs, but they are supported
for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
check for full history of applied IPsec transforms.
o References counting rules for security policies and security
associations were changed. The proper SA locking added into xform
code.
o xform code was also changed. Now it is possible to unregister xforms.
tdb_xxx structures were changed and renamed to reflect changes in
SADB/SPDB, and changed rules for locking and refcounting.

Summary:
i.MX5 and PowerPC use a very similar eSDHC controller, which is also
similar to the uSDHC controller used by i.MX6. The imx_sdhci driver works
almost completely with PowerPC, with some minor tweaks.
There is one caveat with this: reset currently does not work on PowerPC, so has
been #ifdef'd out until this can be tracked down and fixed. If resets are done
the controller will timeout all data transactions. Without a reset, it appears
to work just fine.
This is part 3, following up r308186 and r308187.
Test Plan:
This has been tested on a PowerPC QorIQ P1022 board. It has not been
tested on i.MX, but no regressions are expected.

Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement. setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).
Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.
Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.
Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used. However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.
Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI. Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.

Summary:
This enables some features of the DIU, using a static configuration,
specified either via a 'edid' property on the 'display' FDT node, or a
'video-mode' environment variable (bootarg). 'video-mode' was chosen because it
matches u-boot's naming, so it can be set with:
setenv bootargs video-mode=${video-mode}
at the u-boot CLI.
Mouse cursor is not supported currently, as a hardware cursor is not supported
by framebuffer VT yet. Currently it only supports a 32bpp ARGB (actually BGRA)
format, and only a single composite plane, at up to 1280x1024.

Summary:
MPC85XX and QorIQ are very similar. When the DPAA dTSEC driver was
added, QORIQ_DPAA was brought in as a config option to support the differences
in hardware register settings between QorIQ (e500mc-, e5500- based) SoCs and
QUICC (e500v1/e500v2-based) SoCs, particularly in the Local Access Window (LAW)
target settings.
Unify these settings using macros to hide details and ease porting, and use a
new function (mpc85xx_is_qoriq()) to distinguish between QorIQ and QUICC SoCs at
runtime.
An alternative to using the function could be to use a variable initialized at
platform attach time, which may incur less overhead at runtime. Since it's not
in the critical path once booted, this optimization doesn't seem necessary at
first pass.

Import portions of the PowerPC OF PCI implementation into new file
"ofwpci.c", common for other platforms. The files ofw_pci.c and ofw_pci.h
from sys/powerpc/ofw no longer exist. All required declarations are moved
to sys/dev/ofw/ofwpci.h. This creates a new ofw_pci_write_ivar() function
and modifies some others methods. Most functions contain existing ppc
implementations in the majority unchanged. Now there is no need to have
multiple identical copies of methods for various architectures.

into a new function that other platforms can share.
This creates a new ofw_reg_to_paddr() function (in a new ofw_subr.c file)
that contains most of the existing ppc implementation, mostly unchanged.
The ppc code now calls the new MI code from the MD code, then creates a
ppc-specific bus_space mapping from the results. The new arm implementation
does the same in an arm-specific way.
This also moves the declaration of OF_decode_addr() from ofw_machdep.h to
openfirm.h, except on sparc64 which uses a different function signature.
This will help all FDT platforms to set up early console access using
OF_decode_addr().
QorIQ SoCs (e5500 core, P5 family) have 2 BARs for local access windows, while
MPC85XX, and P1/P2 families use only a single BAR register.
This also adds the QORIQ_DPAA option, mutually exclusive to MPC85XX, to handle
this difference.

Summary:
The RouterBoard uses a predefined partition map which doesn't exist in the fdt.
This change allows overriding the fdt slicer with a custom slicer, and uses this
custom slicer to define the flash map on the RouterBoard RB800.
D3305 converts the mpc85xx platform into a base class, so that systems based on
the mpc85xx platform can add their own overrides. This change builds on D3305,
and creates a RouterBoard (RB800) platform to initialize the slicer override.

For compatibility, 'device windtunnel' is still supported, but one should use
'device adm1030' instead, and this has been updated in GENERIC and NOTES.
The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.
As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.
