6489412064 Remove #include <machine/frame.h> from all the arm code that doesn't
really need it.  That would be almost everywhere it was included.  Add
it in a couple files that really do need it and were previously getting
it by accident via another header.

69d75558a7 Remove all #include <machine/pmap.h> from arm code. It's already
included by vm/pmap.h, which is a prerequisite for arm/machine/pmap.h
so there's no reason to ever include it directly.

Thanks to alc@ for pointing this out.

ec4081c10a Maximize available kva space by doing static device mapping from the top
of the address space downwards, and then returning the lowest mapped
device address from initarm_lastaddr().  This adds over 500MB of kva
space compared to the old way of hardcoding the end address as 0xE0000000.

Also, pre-map most of the SoC's common memory-mapped devices using 1MB
section mappings so that all device access uses just a few TLB entries.
Graphics devices aren't mapped this way yet, but probably should be.

To provide this new functionality without pasting identical code into
multiple imxNN_machdep.c files, rework the imx machdep code so that
things common to the whole family of SoCs are in a new imx_machdep.c file.
The rewritten imxNN_machdep.c files contain just things specific to an
individual SoC.

0b8a792e0b Make devices with registers into the KVA region work reliably. Without this,
previous KVA allocations (which the PMAP lazily invalidates) in TLB0 could
shadow device maps in TLB1. Add a big block comment about some of the
caveats with this approach.

b5c192462c Handle (in a slightly ugly way) ePAPR-type loaders that just place a
device tree into r3. Rather than worrying about mapping that tree, reserving
its space in the global physical memory space, etc., just copy it to some
memory after the kernel.

9dae57e134 Start splitting pfvar.h into internal and external parts.
- Provide pf_altq.h that has only stuff needed for ALTQ.
- Start pf.h, that would have all constant values and
  eventually non-kernel structures.
- Build ALTQ w/o pfvar.h, include if_var.h, that before
  came via pollution.
- Build tcpdump w/o pfvar.h.

61a3ac6e27 The MII layer shouldn't care about administrative status of an
interface. Make MII drivers forget about 'struct ifnet'.

Later plan is to provide an administrative downcall from ifnet
layer into drivers, to inform them about administrative status
change. If someone thinks that processing MII events for an
administratively down interface is a big problem, then drivers
would turn MII processing off.

The following MII drivers do evil things, like strcmp() on
driver name, so they still need knowledge of ifnet and thus
include if_var.h. They all need to be fixed:

sys/dev/mii/brgphy.c
sys/dev/mii/e1000phy.c
sys/dev/mii/ip1000phy.c
sys/dev/mii/jmphy.c
sys/dev/mii/nsphy.c

dce533f390 Be a bit more flexible in how we find the console from the properties on
/chosen, following the list of allowed console properties in ePAPR. Also
do not require that stdin be defined and equal to stdout: stdin is
nonstandard (for ePAPR) and console in an unexpected place is after all
better than no console.

33724f17d2 Interrelated improvements to early boot mappings:
- Remove explicit requirement that the SOC registers be found except as an
  optimization (although the MPC85XX LAW drivers still require they be found
  externally, which should change).
- Remove magic CCSRBAR_VA value.
- Allow bus_machdep.c's early-boot code to handle non 1:1 mappings and
  systems not in real-mode or global 1:1 maps in early boot.
- Allow pmap_mapdev() on Book-E to reissue previous addresses if the
  area is already mapped. Additionally have it check all mappings, not
  just the CCSR area.

This allows the console on e500 systems to actually work on systems where
the boot loader was not kind enough to set up a 1:1 mapping before starting
the kernel.

49e368ac48 Wait for DesignWare UART transfers completion before accessing line control
When using DW UART with BUSY detection it is necessary to wait
until all serial transfers are finished before manipulating the
line control. LCR will not be affected when UART is busy.
In addition, if Divisor Latch Access Bit is being set in order to
modify UART divisors:
1. We will get BUSY interrupt if interrupts are enabled.
2. Because LCR will not be affected the THR and (even worse) IER
   contents will be corrupted. This will lead to console hang.

165de3f338 Fix a couple of bugs in the fasttrap emulation of a "push %rbp" instruction:
the code was trying to save the stack pointer rather than the frame pointer,
and the arguments to copyout(9) were reversed, so nothing ended up being
saved on the stack. This would cause process crashes when the pid provider
was being used to instrument calls of a function starting with this
instruction.

8cf53c1244 Begin fleshing out a knob to enable/disable bluetooth coexistence.
Some firmware versions seem to get very unhappy if they're sent btcoex
commands when they don't actually have bluetooth hardware in them.
So, disable sending them those commands.

Tested:

* 5100 (which has bluetooth, no problems)
* 4965 (which doesn't have bluetooth, but didn't seem to crash)
* 6200 (no bluetooth, seems to get unhappy being sent bluetooth commands.)

2e6fe9b630 Temporarily disable multi-rate retry (link quality) and eliminate rate
index lookups.

* My recent(ish) change to iwn(4) and the net80211 rate control API to
  support 11n rates broke the link quality table use.  So, until I or
  someone else decides to fix it, let's just disable it for now.

* Teach iwn_tx_data_raw() to use the iwn_rate_to_plcp() function.

* Eliminate two uses of the net80211 rate index lookup functions - they
  are only for legacy rates and they're not needed here.

This fixes some invalid looking rate control TX issues that showed up
on my 4965 but it doesn't fix the two TX hangs I've noticed. Those look
like DMA related issues.

Tested:

* 4965, STA mode
* 5100, STA mode

This is another AR9331 board similar to the Carambola2. It has different

They make a variety of boards that mostly differ on the amount of RAM/flash
available.  Alfa Networks graciously donated a handful of 64MB RAM/16MB flash
boards so I can finish off 802.11s support for the AR93xx chips and do up
a tech demonstration with it.

This is enough to bring up the board.
