083e2b01a9 uavobject: Use linker to produce uavobj initcalls
The UAVObject initcall list is now automatically
generated at link time based on the exact set of
UAVObjects linked into the firmware image.

This will allow any subset of UAVObjects to be
used in any firmware image.

The uavobj_initcall() macro automatically adds the
marked function's address into the .initcalluavobj.init
ELF section.

The UAVObjectsInitializeAll() function now simply
iterates over the functions listed in the
.initcalluavobj.init section and calls them.

You can see the contents of this section in the ELF file
like this:
  ./tools/arm-2009q3/bin/arm-none-eabi-objdump \
      --syms -j .initcalluavobj.init \
      ./build/openpilot/OpenPilot.elf

This is fundamentally the same mechanism that the Linux
kernel uses to initialize the specific set of components
that the user has selected in their kernel configuration.

00a3e82c70 CC-6 PIOS/SPI: Add semaphore to SPI device structure that can be used to ensure
only one CS line is asserted.  No checks are enforced on this by the SPI code
as I cant see a clean way of it being aware of the CS lines.  We could add
another CS mode those which is driver managed per transfer and has a GPIO i
line for each device.

4b4a66c2d7 PiOS/I2C: Lots of small changes. Added a few weird bus events that are
sometimes thrown, and made errors not lock it up by default.  It works for me,
but since this has historically been associated with lots of lock ups please
check your systems carefully.

PiOS/I2C: Make the bus by default try to recover from errors instead of locking
up

PiOS/I2C: After a bus error and clocking all previous data create a STOP
condition to make sure bus is released (note, this also requires creating a
START condition first)

PiOS/I2C: If the same event hits the I2C bus twice in a row then disregard
second one, there is no situation where we should get the same event multiple
times that matters and this gets us out really quickly to catch the real
events.  I was seeing this with repeated 0x70084 which means byte transmitted.
This is related to STM32 bugs in the IRQ timings I believe.

PiOS/I2C: 1) Mask out some bits we don't care about in the event flags
2) Don't lock up if the give semaphore fails, although why it does is strange
3) Recover from bus failure through the "auto" state path instead of just
coding state

PiOS/I2C: Change the reset bus code to follow
http://www.analog.com/static/imported-files/application_notes/54305147357414AN686_0.pdf
(thanks for the reference Neontangerine).  Although this may actually NOT clear
the bus the first time through, subsequent bus errors should eventually clock
it out.  The up side is it is less likely to clock a bunch of 1s into an ESC
and make it run up.

PiOS/I2C: Some cleaned up code for getting a snippet of the history when
something strange happens

PiOS/I2C: Export logging information from I2C through a UAV object

PiOS/I2C: Improve the diagnostic information

PiOS/I2C: Need to handle the event 0x30084.  This seems to happen between a
byte transmitted and new byte started

PiOS/I2C: Handle the NACK condition by simply going to the stopping state.

PiOS/I2C: Add a new NACK state to handle sending the STOP signal after a NACK
following the STM documentation.  Other error conditions still are not dealt
with.

PiOS/I2C: Should handle the NACK condition from all the write cases.  Need to
think about read cases

I2C bus errors are now recoverable.  The bus is properly reset
and an error indication is now provided to the caller whenever
a bus error occurs during processing of the transaction list.

For now, the users of the I2C layer just retry infinitely on
failure.  The BMP085 and HMC5843 code should be changed to
report errors to its callers to allow a more sensible retry
strategy.

7d5463e5e6 i2c: Move polling for bus stopped from ISR to task/mainloop
Occasionally, the I2C driver races with the STM32 I2C peripheral
at the end of a bus cycle.  This leaves the bus in an errored
state and the stop condition is not properly asserted on the bus.

The polling for the stopped condition was previously implemented
in ISR context since it was expected to be nearly instananeous.
In the error condition, however, the stop condition will never
happen.  The polling for this case is now done by the initiating
task (or mainloop on the AHRS) to prevent the timeout condition
from triggering the watchdog.

4ca10e92c7 OP-121 OP-122 Flight: Improved USB HID communication.
1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
  2. Moved buffer.c to general flight/Libraries location
  3. Removed the 62 byte transmission limitation by adding a transmission buffer
  4. Sped up USB communication by increasing endpoint polling frequency

Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting.  The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission.  The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission.  This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.

47c36b3da0 i2c: fix error in FSM for restarted reads
The transition from the ADDR state to the read state
was broken for non-final reads.  The FSM diagram was
also wrong for this transition.

Since reads are always the last transaction in a sequence
in our current usage, this doesn't actually fix any known
bugs.

98822bff98 i2c: force bus free on warm starts
Since the i2c bus is bidirectional, there are certain
states (eg. part way through a read) where the slave
device is in control of driving the SDA line.

On a cold start (power on), the slave devices are all
quiescent and will not drive the bus.  However, on a warm
start (eg. watchdog or jtag restart), it is possible that as
the CPU boots, the slave device may be holding the SDA line
low.  This is a bus busy condition and will prevent the I2C
bus master in the CPU from being able to seize the bus during
init.

The fix for this is to clock the i2c bus sufficiently to ensure
that the the slave device finishes its transaction and releases
the bus.

Once the slave has released the bus, the bus master can properly
initialize and assert a STOP condition on the bus.

f74c6ffdd5 i2c: rewrite i2c layer
The STM32 I2C block has a number of errata associated with it.
These errata are primarily related to timing sensitivities between
the peripheral and the interrupt handler.  In particular, the
correct generation of the stop bit relies on the I2C IRQ running
immediately and not being held off for any reason.

NOTE: The I2C interrupts must be the highest priority IRQs in the
      system to ensure correct operation.

I2C protocol is now implemented as a formal state machine.
See: stm32_i2c_fsm.{dot,jpg} for FSM description.

I2C init is now expressed by const initializers in pios_board.c
for both OP and AHRS boards.

I2C device drivers (ie. bmp085/hmc5843) now pass in const arrays
of an unlimited number of bus transfers to be done atomically.
The I2C adapter driver now handles all bus-level locking across the
list of transactions.  Generation of start/restart/stop conditions
are handled automatically over the list of transactions.

Timeouts have been removed from the API for now.  May be added
back later.

This driver has run error free on both the OP and AHRS boards for
up to 48hrs but it still sometimes fails earlier than that on the OP
board.  There is another possible set of improvements to the driver
that could employ the DMA engine for transfers of >= 2bytes.  This
change would reduce the timing sensitivities between the peripheral
and the driver but unfortunately, both the SPI and I2C interfaces
share the DMA1 engine.  That means only one of these two peripherals
can use the DMA engine and right now, SPI between OP and AHRS is
already using it.

Failures are currently fatal and will lock up the CPU.  This allows
useful information to be obtained in the failure cases.
