a94a63f0a6 An MMC/SD/SDIO stack using CAM
Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.

Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items
have been overlooked.

e9804ab2bd [rpi] Use compatibility string from upstream DTB for I2C controller
FreeBSD uses upstream DTB for RPi3 build and compatibility string for
i2c device is different there. Add this new string to compatibility data.

55dae242e6 Add and use a MMC_DECLARE_BRIDGE macro for declaring mmc(4) bridges
as kernel drivers and their dependency onto mmc(4); this allows for
incrementing the mmc(4) module version but also for entire omission
of these bridge declarations for mmccam(4) in a single place, i. e.
in dev/mmc/bridge.h.

b440e965da o Another round fixes for mmc(4), mmcsd(4) and sdhci(4) regarding
comments, marking unused parameters as such, style(9), whitespace,
  etc.
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
  - Remove redundant assignments of the default bus_generic_print_child
    device method (I've whipped these out of the tree as part of r227843
    once, but they keep coming back ...),
  - use DEVMETHOD_END,
  - use NULL instead of 0 for pointers.
o Trim/adjust includes.

f1f425aea0 [rpi] rpi3 should use the same cpufreq logic as rpi2, not rpi-b
RPi3 cpufreq is more like that on RPi2. Setting arm frequency
above min (say, "sysctl hw.cpufreq.arm_freq=600000001") turns on
turbo mode, and the firmware automatically raises voltage, sets
frequency to max 1200MHz, and throttle when overheat, etc.

Swap if/else parts and use SOC_BCM2835 def so RPi3 can share the
same cpufreq logic as RPi2, instead of falling to that for RPi.

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.

3a48aebfbe [rpi] Fix bcm2835_audio locking and samples starvation
Rework general approach to locking and working with audio worker thread:

- Use flags to signal requested worker action
- Fix submitted buffer calculations to avoid samples starvation
- Protect buffer pointers with locks to fix race condition between callback
  and audio worker thread
- Remove unnecessary vchi_service_use
- Do not use lock to serialize VCHI requests since only one thread issues them now
- Fix unloading signaling per hselasky@ suggestion
- Add output to detect inconsistent callback data caused by possible firmware bug
  https://github.com/raspberrypi/firmware/issues/696
- Add stats/debug sysctls to troubleshoot possible bugs

Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to
