- Omit needless spltty in plcomstart.
- Comment on lock order.
- Update confusing comment about hangup delay.

mlelstv | Add support for FIFOs and hardware flow-control to plcom driver.
Add a PLCOM_TYPE_GENERIC_UART variant to match SBSA requirements.

jmcneill | plcom: speed up close with HUPCL set
Instead of incurring a 1s penalty on close of a plcom device with HUPCL set,
defer the sleep until the next open, and only sleep if necessary.

Backout previous - it breaks rpi console for me and jak.

reinoud | Improve support for transmit fifo support for plcom.
As Nick, Michiel and I concluded this driver needs a big overhaul since its
logic is modelled on the standard com.c driver which doesn't have the plcom's
treshold interrupt at al.
On Nicks request, the HW FIFO support hasn't been enabled by default on the
RPi though.
Tested with the RPi.

| 1.11 |
| 25-Jul-2012 |
skrll | Add support for the PL011 to plcom. Pull across a bunch of fixes from
com(4) while I'm here and do some other tidyup.
Tested on a RaspberryPi.
PL010 not tested.

skrll | Replace the simple_lock with a kmutex_t. Update the locking to match
com(4) in the few places it didn't already.

tls | branches: 1.8.2;
Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.
ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

tls | branches: 1.7.2;
First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>. This change includes
the following:
An initial cleanup and minor reorganization of the entropy pool
code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are
fixed. Some effort is made to accumulate entropy more quickly at
boot time.
A generic interface, "rndsink", is added, for stream generators to
request that they be re-keyed with good quality entropy from the pool
as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is
adjusted to use the rndsink interface for rekeying, which helps
address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random
number generator quality is provided (libkern/rngtest.c). This
is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is
based on an implementation of the NIST SP800-90 CTR_DRBG by
Henric Jungheim. This generator users AES in a modified counter
mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers
of randomness. The arc4random/arc4randbytes API is deprecated for
in-kernel use. It is replaced by "cprng_strong". The current
cprng_fast implementation wraps the existing arc4random
implementation. The current cprng_strong implementation wraps the
new CTR_DRBG implementation. Both interfaces are rekeyed from
the entropy pool automatically at intervals justifiable from best
current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as
the old arc4randbytes(), and cprng_strong() is about 20% faster
than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional
kernel component, as it is required by cprng_strong, which is
not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at
startup time; if it fails, the system will reboot. There is
approximately a 3/10000 chance of a false positive from these
tests. Entropy pool _input_ from hardware random numbers is
subjected to the rngtest tests at attach time, as well as the
FIPS continuous-output test, to detect bad or stuck hardware
RNGs; if any are detected, they are detached, but the system
continues to run.
A problem with rndctl(8) is fixed -- datastructures with
pointers in arrays are no longer passed to userspace (this
was not a security problem, but rather a major issue for
compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked
up to the new generators, but the /dev/*random pseudodevices
are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

chs | branches: 1.2.4; 1.2.6; 1.2.8; 1.2.10;
remove the COM_MPLOCK option. always include the spinlock in the softc
and always call the simple_* locking functions. the locking functions
are compiled out if they are not needed anyway, so a separate option
for this doesn't gain anything.
this also fixes the serial console on my alpha ES40 (which doesn't make much
sense since the com driver should still be under the big lock on alpha,
but whatever).

(requested by skrll in ticket #454).
don't mix #define<TAB> and #define<SPACE> in a file.
avoid warning with options PLCOM_DEBUG for INTEGRATOR.
Rename register values. No functional change - same code before and after.
Existing names are prefixed with PL01X_ where they're common between the
PL010 and the PL011. The PL010_/PL011_ prefixes are added where they're
found only on the respective chips.
Replace the simple_lock with a kmutex_t. Update the locking to match
com(4) in the few places it didn't already.
DOH. Replace a line that got accidently deleted in the last commit.
device_t/softc split
struct device * -> device_t
struct cfdata * -> cfdata_t
Add the 'Z' to the 1176 cpu product name.
ok matt@
Fix locking botch introduced in 1.36.
Fix a KASSERT. From/OK'ed by matt@
Fix racy softint dispatch that lead to KASSERT(si->si_active) in
softint_execute
Discussed with matt@. "Looks good to me"
Add the documented ARM11[37]6 Auxiliary control register defines.
Add support for the ARM1176JZS
Add a flag for the lack of LED_ON in HOST_CTL (ti omap3 doesn't do that).
Provide a method for attachments to specify capabilites.
Add support for the PL011 to plcom. Pull across a bunch of fixes from
com(4) while I'm here and do some other tidyup.
Tested on a RaspberryPi.
PL010 not tested.
Initial commit of support for the RaspberryPI (www.raspberrypi.org)
This is enough for serial console via the gpio header pins and to get to
multiuser.
A huge thank you to Matt Thomas for all his help.
Add RPI to KERNEL_SETS
Remove #if 0 code.
