MFC r266647, r270912, r273089:

Reduce the diff between the PandaBoard and BeableBone kernel configs

Resync comments about scbus and pass for life after AHCI joined CAM.

Uncomment general options from the Pandaboard config. These are in other
configs and there is no reason for them not to be here.

MFC 265155, 265254:

Omit from the universe build all config files tagged with #NO_UNIVERSE.

Add FDT to the VYBRID kernel.

MFC 263301

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

MFC 263245: Make all the comments '# ' and align to same column.

MFC 257774, 256760, 262916, 262905, 262918, 262919, 262920, 262921, 262924,

262950

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.

Move all the files named foo/common.c to foo/foo_common.c

Initial cut for DTS on the hl201 board.

Add commented out dts for sam9260ek as well as early printf support.

Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")

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
then...

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.

MFC r261570, r261572

Revert r260440 (add USB_HOST_ALIGN to all configs, it's only needed for
platforms with a 64-byte cacheline size).

Add option USB_HOST_ALIGN=64 for all SoCs that have 64 byte cache lines.

MFC r260440, r260441, r260447, r260490, r260493

Add option USB_HOST_ALIGN to configs that contain 'device usb'.

Update dts files of Cubieboard1,2 to use 1GB memory.

Add a function to print the contents of the static device mapping table,

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

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.
