0e7a801e9e hmc5843: Add support for DRDY signal from magnetometer
The DRDY signal from the magnetometer is connected to PB8
on the STM32.  This pin is now configured as an external
interrupt and is now used to signal when new data is
available from the magnetometer.

88e73906d0 i2c: Add recovery code for i2c bus errors
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.

0122394481 i2c: consolidate handling of AUTO transitions
AUTO transitions in the FSM are now handled immediately
after processing each newly injected event rather than only
at the end of the EV ISR.

This consolidation allows the upcoming addition of event
injection from both the EV and ER ISR contexts.

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.

840f7ff456 A version of the firmware that successfully Acks back and forth over HID. Still need to refine the PIOS interface and make GCS strip out the report ID data (if necessary). Also note: currently if you run too many modules the watchdog timer kicks in. I haven't determined if this is due to an interrupt binding up or what (and why it doesn't happen more often since I can't find any code that explicitly resets the WWDG).

a3a2dbd634 spi: Add support for hardware CRC generation/checking
PIOS SPI devices may now make use of automatic CRC generation
and checking on block transfers.  Only supports CRC8 for now.

Since the SPI interface CRC calculation continues across message
boundaries (ie. not reset on every transfer), we must manually reset
the CRC registers for every transfer to allow the two sides of the
link to resynchronize.

Unfortunately, resetting the CRC registers requires disabling the
SPI peripheral which must now be done on every block transfer.

Note: The last byte of the tx buffer is never sent and is assumed to
      be a place holder for the tx CRC8.
Note: The last byte of the rx buffer is expected to hold the rx CRC8.
