iflib is already a module, but it is unconditionally compiled into the
kernel. There are drivers which do not need iflib(4), and there are
situations where somebody might not want iflib in kernel because of
using the corresponding driver as module.

We already pass -many to the assembler, and -me500 drops 64-bit instruction
handling, for some reason only breaking module building for 64-bit kernels.
Additionally, build with CTF for dtrace.
This brings it closer to par with GENERIC64. In the future I hope to have a
GENERIC64-E and GENERIC-E kernels as Book-E analogues to the GENERIC64/GENERIC
AIM kernels.
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
FreeBSD side.
As this was imported from a Linux tree, it includes some Linux-isms
(ioread/iowrite), so compile with the LinuxKPI for now. This may change in the
future.

These devices bring the configs closer to a desktop-like (GENERIC) kernel
config.
* The Freescale DIU support was added to the config in r306358.
Without keyboard support video support is nearly pointless, so add ukbd and
ums.
* The AmigaOne X5000, and P1022 devboard, both use a variant of the ds1307 RTC
* cpufreq scaling is currently supported by the p1022. More SoCs will be added
eventually.
The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.
Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms. The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.
Note that this driver is still under active development and testing and
may not yet be ready for production use. It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.
To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver. These can be done by setting the following
tunables before loading the cxgbe(4) driver:
hw.cxgbe.config_file=uwire
hw.cxgbe.cryptocaps_allowed=-1

Extend the Book-E pmap to support 64-bit operation. Much of this was taken from
Juniper's Junos FreeBSD port. It uses a 3-level page table (page directory
list -- PP2D, page directory, page table), but has gaps in the page directory
list where regions will repeat, due to the design of the PP2D hash (a 20-bit gap
between the two parts of the index). In practice this may not be a problem
given the expanded address space. However, an alternative to this would be to
use a 4-level page table, like Linux, and possibly reduce the available address
space; Linux appears to use a 46-bit address space. Alternatively, a cache of
page directory pointers could be used to keep the overall design as-is, but
remove the gaps in the address space.
This includes a new kernel config for 64-bit QorIQ SoCs, based on MPC85XX, with
the following notes:
* The DPAA driver has not yet been ported to 64-bit so is not included in the
kernel config.
* This has been tested on the AmigaOne X5000, using a MD_ROOT compiled in
(total size kernel+mdroot must be under 64MB).
* This can run both 32-bit and 64-bit processes, and has even been tested to run
a 32-bit init with 64-bit children.
Many thanks to stevek and marcel for getting Juniper's FreeBSD patches open
sourced to be used here, and to stevek for reviewing, and providing some

Linux has a slightly different device tree definition for DPAA than originally
done in the FreeBSD driver. This changes the driver to be mostly compatible
with the Linux device tree definitions. Currently the differences are:
bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus")
qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus")
fman: compatible = "fsl,fman" (Linux is "simple-bus")
The Linux device tree doesn't specify anything for rgmii in the mdio. This
change still requires the device tree to specify the phy-handle, and doesn't yet
support tbi.
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.

Instead replace it with a different hack, that turns fman into a simplebus
subclass, and maps its children within its address space.
Since all PHY communication is done through dtsec0's mdio space, the FDT
contains a reference to the dtsec0 mdio handle in all nodes that need it.
Instead of using Freescale's implementation for MII access, use our own (copied
loosely from the eTSEC driver, and could possibly be merged eventually). This
lets us access the registers directly rather than needing a full dtsec interface
just to access the registers.
Future directions will include turning fman into more of a simplebus, and not
mapping the region and playing games. This will require changes to the dtsec
driver to make it a child of fman, and possibly other drivers as well.
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.
Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.
This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.
Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.
