In kernel config files, it is supposed to be 'options<space><tab>' not

Initial cut for DTS on the hl201 board.

Set the baud rate if it isn't 0

Make at91_soc_id() public.

Properly round at91 resource on unmapping.

Move AT91 AIC related stuff to own file.

Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.

Follow r262916 with one more config file that references a renamed common.c

Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until

Remove all dregs of a per-thread undefined-exception-mode stack.

Rework the VFP code that handles demand-based save and restore of state.

Always call vfp_discard() on thread death.

When a thread begins life it doesn't own the VFP hardware state on any cpu.

Make undefined exception entry MP-safe.

Back out r253779 & r253786.

Decouple yarrow from random(4) device.

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.

* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.

* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah

* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.

* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.

* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

Revert last change. It was accidental.

Remove some unused variables/externs that have been copied too many times...

Strip trailing whitespace.

Remove pty(4) from our kernel configurations.

As of FreeBSD 8, this driver should not be used. Applications that use
posix_openpt(2) and openpty(3) use the pts(4) that is built into the
kernel unconditionally. If it turns out high profile depend on the
pty(4) module anyway, I'd rather get those fixed. So please report any
issues to me.

The pty(4) module is still available as a kernel module of course, so a
simple `kldload pty' can be used to run old-style pseudo-terminals.

Add missing options so modules build/load correctly.

Fix a zyd(4) comment typo that was copy+pasted into most kernel config files.

- Move USB serial drivers earlier to match their placement in other kernel
configs.
- Add descriptions to various USB drivers.
- Move the USB wireless drivers into a new section.
- Add ulscom to the list of USB serial drivers.

- Use "device\t" and "options \t" for consistency.

Disconnect drivers that haven't been ported to MPSAFE TTY yet.

As clearly mentioned on the mailing lists, there is a list of drivers
that have not been ported to the MPSAFE TTY layer yet. Remove them from
the kernel configuration files. This means people can now still use
these drivers if they explicitly put them in their kernel configuration
file, which is good.

People should keep in mind that after August 10, these drivers will not
work anymore. Even though owners of the hardware are capable of getting
these drivers working again, I will see if I can at least get them to a
compilable state (if time permits).

Make genclock standard on all platforms.

Note this includes changes to all drivers and moves some device firmware

Default to booting off the SD card. It is more useful, and a full

I could find at the store today was 512MB (and it was only $10 after
rebate), with a 2GB card for as low as $25.00...

Remove COMPAT_43 from GENERIC (and other kernel configs). For amd64 there's
an explicit comment that it's needed for the linuxolator. This is not the
case anymore. For all other architectures there was only a "KEEP THIS".
I'm (and other people too) running a COMPAT_43-less kernel since it's not
necessary anymore for the linuxolator. Roman is running such a kernel for a
for longer time. No problems so far. And I doubt other (newer than ia32
or alpha) architectures really depend on it.

This may result in a small performance increase for some workloads.

If the removal of COMPAT_43 results in a not working program, please
recompile it and all dependencies and try again before reporting a
problem.

The only place where COMPAT_43 is needed (as in: does not compile without
it) is in the (outdated/not usable since too old) svr4 code.

Note: this does not remove the COMPAT_43TTY option.

Rather than pull in all the phy, just pull in the lxt phy that we need

Import support for the Atmel AT91RM9200 CPU/Microcontroller. This SoC
is a ARM920T based CPU with a bunch of built-in peripherals. The
inital import supports the SPI bus, the TWI bus (although iicbus
integration is not complete), the uarts, the system timer and the
onboard ethernet. Support for the Kwikbyte KB9202
(http://www.kwikbyte.com) board is also included, although there's no
reason why the 9200 and the 9201 wouldn't also work. Primitive
support for running under the skyeye emulator is also provided
(although skyeye's support for the AT91RM9200 is a little weak).

The code has been structured so that other members of Atmel's arm family can
be supported in the future. The AT91SAM9260 is not presently supported
due to lack of hardware. The arm7tdmi families are also not supported
becasue they lack an MMU.

Many thanks to cognet@ for his help and assistance in bringing up this
board. He did much of the vm work and wrote parts of the uart and
system timer code as well as the bus space implementation.

The system boots to single user w/o problem, although the serial
console is a little slow and the ethernet driver is still in flux.

grateful to their support of the FreeBSD project in this manner.
