f02e47dc1e Snapshot. This passes the build test, but has not yet been finished or debugged.
Contains:

* Refactor the hardware RNG CPU instruction sources to feed into
the software mixer. This is unfinished. The actual harvesting needs
to be sorted out. Modified by me (see below).

* Remove 'frac' parameter from random_harvest(). This was never
used and adds extra code for no good reason.

* Remove device write entropy harvesting. This provided a weak
attack vector, was not very good at bootstrapping the device. To
follow will be a replacement explicit reseed knob.

* Separate out all the RANDOM_PURE sources into separate harvest
entities. This adds some secuity in the case where more than one
is present.

* Review all the code and fix anything obviously messy or inconsistent.
Address som review concerns while I'm here, like rename the pseudo-rng
to 'dummy'.

c6c7b2912c Yarrow wants entropy estimations to be conservative; the usual idea
is that if you are certain you have N bits of entropy, you declare
N/2.

8e015fd886 Octeon 2 (6xxx) and newer CPUs don't use the clock CPU speed for its
I/O clock. Thankfully, the simple executive provies a way to querry
the proper clock that works on all models. Move to asking for the SCLK
via this interface.

This gets the serial console working after we start init and open the
console and set the divisor (which turned the output from good to
bad). I can login on the console now.

405b925e39 Don't disable PCIe just because the host is not a PCI host; the latter flag
only applies to non-PCIe systems.  If PCIe is in target mode, it will simply

1f51baaa92 Use Simple Executive LED display routines, which correctly use the LED base
address passed from the bootloader, rather than using a hard-coded value.

Make FreeBSD announce itself on the LED display similar to other kernels.

Remove uses of the previous LED routines, which were under-used and only used
in drivers for what seem like debugging purposes, despite those drivers being
widely-tested.

Remove several inlines for accessing memory that duplicate other functions
which are now used instead, as they are now entirely unused.

84db023ec1 Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.
This makes our naming scheme more closely match other systems and the
expectations of much third-party software.  MIPS builds which are little-endian
should require and exhibit no changes.  Big-endian TARGET_ARCHes must be
changed:
	From:		To:
	mipseb		mips
	mipsn32eb	mipsn32
	mips64eb	mips64

An entry has been added to UPDATING and some foot-shooting protection (complete
with warnings which should become errors in the near future) to the top-level
base system Makefile.

dc4ee6ca91 Merge the Cavium Octeon SDK 2.3.0 Simple Executive code and update FreeBSD to
make use of it where possible.

This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.

Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.

Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive.  The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.

ecdb6b0261 Fix promiscuous mode with if_octm:
o) The MAC set must occur before the multicast list is set up as the former
   will enable the CAM unconditionally, while promiscuous mode disables it,
   so if promiscuous mode is to be set this must occur after the MAC is
   programmed.
o) The multicast list must be set up unconditionally as even if flags have
   not changed, if the interface has gone through a reinitialization, the
   state of the CAM as changed by the MAC initialization could be incorrect.
o) Call octm_init when flags change, even if the interface is already running.

4228a524fd When creating a handle for a subregion, be sure to actually math out the new
handle address, where we're using handles as raw addresses.

This fixes devices with subregions on Octeon PCI specifically, and likely also on
MIPS more generally, where there isn't another bus_space in use that was doing the
math already.
