on-board USB controller. It is not currently enabled because there are
known problems with device communication and until those are fixed I am not
certain that it won't destabilize the system. [1]
o) Add the "cryptocteon" opencrypto device based on the OCF device written by
David McCullough. It is not currently enabled because until support for
saving/restoring coprocessor 2 state on context switch is available, it runs
with interrupts disabled, which tends to pessimize performance over using a
software crypto facility. Tests using this driver which are not negatively
affected by it running with interrupts disabled show it to be substantially
faster than software for large blocks.

library:
o) Increase inline unit / large function growth limits for MIPS to accommodate
the needs of the Simple Executive, which uses a shocking amount of inlining.
o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and
the Octeon SoC.
o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific
board numbers, specifically to support the MR320.
o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd,
which improperly uses an evaluation board's board number and breaks board
detection at runtime. This board is sold by Portwell as the CAM-0100.
o) Add support for the RTC available on some Octeon boards.
o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO
ports can not work unless building for n64.
o) Clean up the CompactFlash driver to use Simple Executive macros and
structures where possible (it would be advisable to use the Simple Executive
API to set the PIO mode, too, but that is not done presently.) Also use
structures from FreeBSD's ATA layer rather than structures copied from
Linux.
o) Print available Octeon SoC features on boot.
o) Add support for the Octeon timecounter.
o) Use the Simple Executive's routines rather than local copies for doing reads
and writes to 64-bit addresses and use its macros for various device
addresses rather than using local copies.
o) Rename octeon_board_real to octeon_is_simulation to reduce differences with
Cavium-provided code originally written for Linux. Also make it use the
same simplified test that the Simple Executive and Linux both use rather
than our complex one.
o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus
to use normal interrupt allocation and setup routines.
o) Use the Simple Executive's bootmem facility to allocate physical memory for
the kernel, rather than assuming we know which addresses we can steal.
NB: This may reduce the amount of RAM the kernel reports you as having if
you are leaving large temporary allocations made by U-Boot allocated
when starting FreeBSD.
o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes
Ethernet interface naming from rgmxN to octeN. The new driver has vast
improvements over the old one, both in performance and functionality, but
does still have some features which have not been ported entirely and there
may be unimplemented code that can be hit in everyday use. I will make
every effort to correct those as they are reported.
o) Support loading the kernel on non-contiguous cores.
o) Add very conservative support for harvesting randomness from the Octeon
random number device.
o) Turn SMP on by default.
o) Clean up the style of the Octeon kernel configurations a little and make
them compile with -march=octeon.
o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple
Executive.
o) Modify the Simple Executive to build on FreeBSD and to build without
executive-config.h or cvmx-config.h. In the future we may want to
revert part of these changes and supply executive-config.h and
cvmx-config.h and access to the options contained in those files via
kernel configuration files.
o) Modify the Simple Executive USB routines to support getting and setting
of the USB PID.
This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
has been renamed to /usr/include/clang/2.8.

lengths. Make MI wrapper code to validate periods in request. Make kernel
clock management code to honor these hardware limitations while choosing hz,
stathz and profhz values.
Executive is a library that can be used by standalone applications and kernels
to abstract access to Octeon SoC and board-specific hardware and facilities.
The FreeBSD port to Octeon will be updated to use this where possible.
- Fixed segmentation fault when an invalid network interface was given.
- More helpful message in case of wrong PIN number.

- Fixed the interface probe routine to only attach to USB interfaces the driver
actually supports. This allows other drivers to attach to things like
MicroSD slots etc.
- Fixed network interface enumeration to be globally sequential instead of
relying on the USB interface numbers. This make sure the first network
interface always is at uhso0 and the second at usho1 and so on.
- Added a radio kill switch; exposed through sysctl.
- Updated the manual page to be verbose about the number of serial ports and
include iCON 452 in the set of tested hardware.

__start_SECNAME and __stop_SECNAME symbols are automatically generated
by ld for orphan sections, i.e. those not explicitely referenced by a
linker script. The symbols are supposed to be placed correspondingly
at the start and the end of the section in output file. In some cases
__start_SECNAME may be placed at the address after the end of the
previous section (if any) and before the start the section. This
happens when following conditions are met:
1. the orphan section is found in more than one input file
2. the orphan section has different alignment requirements across input
files
3. the first instance of the section encountered doesn't have the
greatest alignment requirement
In these conditions resulting output section will be placed at address
after the end of the previous section aligned to the greatest alignment
requirement in the inputs, but __start_SECNAME will be placed at address
after the end of the previous section aligned to the alignment
requirement of the first input in which the section is encountered.
See commit message of r196118 for a concrete example of problems caused
by this bug.
The fix is to place __start_SECNAME inside the section and use ABSOLUTE
directive, rather than placing __start_SECNAME outside the section and
trying to guess address alignment.
This fix is in line with upstream binutils change/fix made between
versions 2.19 and 2.20 in revision of 1.307 ldlang.c.
