8148f4f3d5 Enable usb low and full speed devices connected to the imx6 root hubs.
This enables the PHY circuitry for UTMI+ level 2 and 3, and sets the
flag to tell the ehci code that the root hub has a transaction translator
in it.  For imx6 we can use the standard ehci_get_port_speed_portsc()
function to find out what speed device is connected to the port.

3b7a388b3e Update arm and arm64 counters MD bits.
On arm64 use atomics.  Then, both arm and arm64 do not need a critical
section around update.  Replace all cpus loop by CPU_FOREACH().
This brings arm and arm64 counter(9) implementation closer to current
amd64, but being more RISC-y, arm* version cannot avoid atomics.

59cd18b093 sys/arm/arm/identcpu-v4.c: fix identify_arm_cpu()
identify_arm_cpu() in sys/arm/arm/identcpu-v4.c incorrectly uses a
u_int8_t variable to store the result of cpu_get_control().
It should really use a u_int variable, the same way as done for cpu_ident()
in the same function, as both cpuid and control registers are 32-bit..
This issue causes users of identcpu-v4 to incorrectly report things such as
icache status (bit 12 in cpu control register) and basically anything
defined in bits above bit 7 :-)

The types are for the byte offset and page index in vm object.  They
are similar to off_t, which is defined as 64bit MI integer.  Using MI

93a065e749 Remake support for SMP kernel on UP cpu:
- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
   By this, any SMP kernel can be compiled with SMP_ON_UP support.
 - Enable runtime detection of CPU multiprocessor extensions only
   if SMP_ON_UP option is used. In other cases (pure SMP or UP),
   statically compile only required variant.
 - Don't leak multiprocessor instructions to UP kernel.
 - Correctly handle data cache write back to point of unification.
   DCCMVAU is supported on all armv7 cpus.
 - For SMP_ON_UP kernels, detect proper TTB flags on runtime.

878097c10e [am335x] Fallback to standard video interface bindings when using Linux dts
Historically AM335x LCDC driver used non-standard "hdmi" property to
refer to HDMI framer. There is no such thing in upstream DTS, so to
handle both cases fallback to bindings described in
bindings/media/video-interfaces.txt in Linux documentation.

We still make some assumptions that are not universally true: we
assume that if remote endpoint is available it's going to be HDMI
framer. Which is true for AM335x-based devices currently supported
but may be not true for some custom hardware.

28b3a4a659 Configure the timer capture pin to input mode in the timer control
register, in addition to configuring it as input with the pinmux driver.

There was a control register bit commented as "no desc in datasheet".  A
later revision of the manual reveals the bit to be an input/output control
for the timer pin.  In addition to configuring capture or pulse mode, you
apparently have to separately configure the pin direction in the timer
control register.

Before this change, the timer block was apparently driving a signal onto a
pad configured by pinmux as input.  Capture mode still accidentally worked
for me during testing because I was using a very strong signal source that
just out-muscled the weaker drive from the misconfigured pin.

Commit r312747 ("Setup decoding windows for ARMADA38X") resulted
in build failing for Marvell platforms, which don't have AHCI controller.
This patch provides a fix by adding dummy functions for such cases.

On the occasion rename register dump routine to decode_win_ahci_dump,
in order to avoid confusion.

  more direct.

- Remove armv4 pcpu fields which I added in r286296 but never
  needed to use.

- armv6 pc_qmap_addr was leftover from the old armv6 pmap
  implementation.  Rename it and put it to use in the new one.

e0b79e669b Like r310481 for i386, move the objects used to create temporary
mappings for armv6 pmap zero and copy operations to the MD PCPU region.
Change sysmap initialization to only allocate KVA pages for CPUs that
are actually present.

While here, collapse CMAP3 into CMAP2 (their use was mutually exclusive
anyway) and "recover" some space in PCPU padding that has always been
available due to 64-byte cacheline padding.
