d2e234b53a Adding the code from Dr. Dale to the AHRS. Currently diverges though, but not on the PC.

e3824a6d78 ahrs spi: Add AHRS SPI link management FSM
To the outside world, the AHRS can be in one of only a few
primary states:
 Not present - AHRS is absent or non-responsive via SPI
 Inactive - Only link-level status messages are processed
 Ready - Ready to receive the next application level message
 Busy - Application level message is being processed

Internal to the AHRS, there are many more states that need to be
managed.  This FSM provides the necessary decoupling between the
ISR (which is being driven by the SPI link) and the AHRS main
processing loop which must continue to run its filters independently
of the SPI messaging rate.

With this structure, SPI messages can be received at any time but
processed at only specific points within the filter chains.

89a6d6d912 ahrs spi: Add definition of OP<->AHRS SPI protocol
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.

8d015a57d0 pios spi: support both master and slave configs
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.

90f9e6d309 openocd: support OP and AHRS at the same time
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:
