- syntax error in pios_board_posix.c introduced with Doxygen comment blocks
- platform dependant code had been added to openpilot.c instead of pios_board.c
- redundant header inclusion (stm32... already included by PiOS)

- Added FlighSituation Module (development module for sensor fusion, mostly stub, possibly renamed later)
- Added Navigation Module (development module for navigating towards a point in space - DEVELOPMENT CODE, NOT STABLE YET (I am testing around with this))
- Changed Stabilization Module (uses local reference frame now. Stable except for code cleanup/review. Tested in simulator and outperforms old code.)

The AHRS comms module now sync's with the AHRS and
exchanges interesting data periodically. Whenever
the link to the AHRS is down, the AHRSComms alarm is
raised.
This is fairly basic for now but provides the last
piece of the infrastructure to move data back/forth
between the OP and the AHRS.

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.

The Attitude module will soon be handling updates for all UAVObjects
that require data from the AHRS. To reflect this expansion of scope,
it has been renamed to AHRSComms.

This object currently only holds the serial number of the attached
AHRS board. This will be retrieved each time communications are
(re)established with the AHRS board.
This will eventually be extended to hold some statistics for OP to
AHRS comms.

This object currently holds only the raw magnetometer readings and
an instantaneous heading calculation which are only really useful
for debugging. The contents of this object will change often as
development progresses.
Note: The magnetometer values are often garbage due to a problem
with i2c software on the AHRS.

The input data lines between the OP and AHRS boards had internal
pull-ups enabled. This seemed to be causing issues early on
during development of the inter-board comms. Not sure if this
is still necessary but this is how the current code was tested.

This defines the SPI message format as well as a few
initial messages for moving data across the link.
The v0 messages are place holders for firmware download
in the bootloader.
The v1 messages are to be used by the main application.
Note: This is not the final protocol definition.
Subject to change without notice.

Mark the device specific DMA IRQ handlers as strongly linked
aliases for the genericly named interrupt vector symbol.
Here's how this works...
* The address of the symbol DMA1_Channel2_IRQHandler is written
into the DMA1/Channel2 interrupt vector by the linker script.
* The startup_*.S file specifies Default_Handler() as a weakly
linked alias for DMA1_Channel2_IRQHandler.
* We now override the weakly linked alias with the strongly linked
PIOS_SPI_sdcard_irq_handler().
* This results in the address of PIOS_SPI_sdcard_irq_handler() being
written to the vector table for the DMA1/Channel2 interrupt.
* The PIOS_SPI_sdcard_irq_handler() function is now called whenever
the DMA1/Channel2 interrupt fires.

The AHRSComms alarm will be raised whenever the OP board
is not able to communicate with the AHRS board.
The navigation software on the OP board could use this
alarm to trigger its best attempt at an emergency landing.

- Created a pluggable COM layer
- Converted COM + USART init into static initializers
rather than typedefs
- Generalized the USB HID COM API to match the USART
API.
- Changed USART and COM layers to be data driven rather
than #ifdef'ing/switching on the specifics of each port

Added support for SPI slave configurations to the pios SPI layer.
Converted the board specific configuration for the PIOS SPI layer to
use const static initializers rather than #defines (see pios_board.c).
SPI interface between the OP board and the AHRS is now operational at
a basic level, capable of moving simple single byte messages between
boards. Multi-byte, CRC protected messages will be added on top of this.

Split the floss-jtag.cfg file into separate versions
for OP and AHRS.
Push AHRS onto non-default ports for gdb, tcl and
telnet.
Update the AHRS gdb setup script to point at the new
gdb port.
Add (commented out) example sytax to support distinguishing
between multiple floss-jtag boards that don't have serial
numbers. Uses the usb bus address of each device as the
selector. See this patch posted to the openocd mailing list
for how to add this functionality to openocd:

This fixes the COM interface over USB HID to the point where
it can establish and maintain solid communications with the UAVObject
Browser in the GCS.
Tested only on Linux. The USB HID interface is still disabled for now
until it is tested successfully by a wider group.
Edit telemetry.c and set ALLOW_HID_TELEMETRY to 1 to enable telemetry
over the USB HID interface and report your results in the forum.

FreeRTOS has a strict requirement that even interrupt-safe API calls (ie.
those ending in "FromISR") can only be called from ISRs that are at lesser
or equal priorities to configMAX_SYSCALL_INTERRUPT_PRIORITY. See the
"configKERNEL_INTERRUPT_PRIORITY and configMAX_SYSCALL_INTERRUPT_PRIORITY"
section at:
http://www.freertos.org/a00110.html
The interrupt numbers used on the Cortex-M3 CPU has a somewhat backward
representation of the interrupt numbers so 255 = lowest priority and
0 = highest priority.
The calculation is further complicated by the STM32 implementation only using
the upper 4 bits of the priority value. Only 0x00, 0x10, 0x20, ..., 0xE0, 0xF0
represent useful interrupt priorities.
FreeRTOS requires that MAX_SYSCALL and KERNEL interrupt priorities are expressed
as raw unshifted 8-bit values to be programmed directly into the BASEPRI register.
The priority values passed to the NVIC initialization, however, are expected
to be 4-bit values and are shifted up by 4 within NVIC_Init() for you.
The end result is that we need this arrangement:
[highest priority]
NVIC_0 (Non-maskable-interrupt)
NVIC_1
NVIC_2
[Must NOT call FreeRTOS APIs above here]
configMAX_SYSCALL_INTERRUPT_PRIORITY (now at 48 = 0x30 = NVIC_3)
PIOS_IRQ_PRIO_HIGHEST (cur. NVIC_4)
PIOS_IRQ_PRIO_HIGH (cur. NVIC_5)
PIOS_IRQ_PRIO_MID (cur. NVIC_8)
PIOS_IRQ_PRIO_LOW (cur. NVIC_12)
configKERNEL_INTERRUPT_PRIORITY (240 = 0xF0 = NVIC_15)
[lowest priority]
The previous config had configMAX_SYSCALL_INTERRUPT_PRIORITY set at
191 (0xBF) which is effectively NVIC_11. This was allowing all of
the MID, HIGH and HIGHEST interrupt handlers to preempt the OS in
its critical sections. Since some of these ISRs were calling
FreeRTOS APIs, this would result in corrupting internal data structures
within the OS.
It should be ok to move the configKERNEL_INTERRUPT_PRIORITY to a higher
priority as long as it is less than configMAX_SYSCALL_INTERRUPT_PRIORITY.

The uavobjectgenerator can now generate python classes for each
UAVObject definition. This is useful for writing simple test
applications in python that can exercise the UAVObject handling
code on the embedded boards.
This is a work in progress so the structure of the generated
classes is likely to change.

Commit @583 uncomments the HIDTest task creation. HIDTest task is configured to run at
priority 4 (== tskIDLE_PRIORITY + 4) which is higher priority than the "System" task at
priority 3 (== tskIDLE_PRIORITY + 3).
The HIDTest task never blocks so it prevents the system task (and any other task of priority
less than 4) from ever running.
This commit does not fix the root problem of HIDTest never blocking, but rather lowers
its priority to be equal to the system task so that they share the CPU. This is a
temporary workaround.
