ff0bd87f4e PIOS SPI: Add a second claim bus method for use in ISR. This has no timeout
and uses an ISR safe queue claiming method.  This avoids deadlocks when ISR
blocks other tasks from freeing the bus.

2d27c54d48 com_msg: Create new message based COM layer for bootloaders
The main purpose of this new COM implementation is that it is
much simpler, and requires less code space.  This takes a bit
of the pressure off of the CC bootloader which was right at
the limit of available code space in the bootloader partition.

This is not intended to ever be used by the application.

This driver also formalizes the assumptions in the bootloader's
usage of the COM layer.  All messages are assumed to arrive
in atomic chunks from the HID layer.

b94f4b49a4 usb: major refactoring of USB descriptors, CDC and HID
Summary of changes:
 * USB CDC and HID drivers are completely split apart.
   * This will allow different max buffer sizes for HID and CDC.
 * USB descriptors have been overhauled:
   * Proper structs/macros/enums declared for USB (see pios_usb_defs.h)
   * Two common descriptor definitions.  One for HID+CDC another for HID only.
     See pios_usb_desc_{hid_cdc,hid_only}.c for details.
   * Long standing bugs in OP USB descriptors became much more obvious with the
     new struct definitions.
   * Board specific USB initialization is now in pios_usb_board_data.h in each build target.
   * Definition of USB descriptors is now entirely indpendent of STM32 libs.
     Glue into STM32 libs is provided by pios_usbhook.c.
 * Removed a lot of stale/irrelevant USB #defines throughout the tree.
 * Improved naming consistency throughout USB code:
   * PIOS_USB_HID_* now refers to the HID endpoint code.
   * PIOS_USB_CDC_* now refers to the CDC endpoint code.
   * PIOS_USB_* now refers to the low-level USB code.
   * PIOS_USB_BOARD_* now refers to board-specific USB data
   * PIOS_USBHOOK_* is glue between PIOS and STM32 USB libs.
   * struct usb_* and enum usb_* and USB_* and HID_* are all types from the USB spec.
 * Shrunk the buffer size on the CDC call mgmt endpoint to save some RAM.
 * Made a few more USB related variables static to save some RAM.

that are hooked into the stm32 usb library.

f5e82b8242 spektrum: rename Spektrum to DSM (DSM2/DSMJ/DSMX used by Spektrum and JR radios)
No code changes, just file, variable and define names are changed.

First, it better describes the serial protocol used by DSMx satellite
receivers. Second, many people using Spektrum radio, assume Spektrum
protocol. This is the attempt to address those inaccuracies.

0116e6a007 spektrum: rework DSM2/DSMJ/DSMX driver for explicit DSMX resolution support
- both CC serial ports are now disabled by default (no telemetry);
- serial ports now have DSM2, DSMX (10bit) and DSMX (11bit) options;
- ReceiverGroups now have DSM (MainPort) and DSM (FlexiPort) options.

For DSM2 protocol there is an explicit resolution bit in the stream, so
the DSM2 should be selected. For DSMX there is no such bit, and user
should choose the resolution from the list configuring the spektrum port.
ReceiverGroups have single DSM option which is handled by the same driver.

Downside: this implementation saves received frame first, unrolls by the
end of frame. This should be ok, but may be improved by unrolling channels
on the fly in the rx callback.

Another minor difference is that a ChannelGroup is now bound to port:
DSM (MainPort) or DSM (FlexiPort). This was considered as acceptable
solution in order to not have 6 DSM options for each ChannelGroup and
even more in case of new DSM protocol variations.

Known problem: it is not possible to choose same protocols like
DSM2/DSM2 for two ports. It can be enabled by adding an exception to
common rule, though.

The DSMX throttle channel misbehavior (zero value) is not treated
specially yet. It should trigger the failsafe being out of bounds.
More info and data dumps are required to handle this properly.

58d0812309 sbus: better frame syncronization, some cosmetic changes
In the previous version the decoder could in rare cases get synced from
the middle of data stream in case of data byte equal to the S.Bus start
of frame (SOF) byte (wrong data will be rejected but it was not perfect).
Now it waits for the real start of frame and then checks the SOF byte.

62bca651d5 spektrum: alternative DSMx (DSM2/DSMJ/DSMX) driver
- does not glitch when used in 2-frame mode (DM9, 9503, etc)
- does NOT provides yet DSMX stream decoding - do NOT merge
- uses a bit more time in the interrupt, but frees 16 bytes of RAM.
  This is done to help decoding the weird DSMX stream which does not
  contain explicit resolution/frame/lost frames info and needs special
  processing (to be done yet).

- A missing driver is 65534
- An invalid channel is 65535

ManualControl: Make it deal with the values explicitly.  A timed out value
should not be treated like a minimum duration signal.  Instead it does not
updated the scaled value but marks the data window as invalid to trigger the
failsafe.

2f86e4dd4f Make PWM/PPM and Servo drivers play nicely together
PWM and PPM can now coexist in the same load and be
selected at boot time via the hwsettings UAVObject.

This is basically a complete restructuring of the
way the drivers interact with the TIM peripheral in
the STM32.

As a side effect, the PWM and PPM drivers are now
ready to support multiple instances of each.

This also provides the first step toward being able
to reassign some of the PWM input pins to be servo
output pins.  Still more work required, but this is
a good start.

06cdeb7b61 rcvr: support multiple simultaneous receivers
Now also supports multiple instances of the Spektrum driver.
These are configured as Spektrum1 and Spektrum2.

829b8b83f6 rcvr: Add GCS receiver driver for rcvr via telemetry
This allows the GCS to emulate a receiver device via the
telemetry link.

Select "GCS" as your input type in the manualcontrol config
screen and calibrate it as normal.

Note: The expected values for the channels are in microseconds
      just like a PWM or PPM input device.  The channel values
      are validated against minimum/maximum pulse lengths just
      like normal receivers.

8b0415d905 bl: alternate stopwatch for small bootloaders
The small bootloaders (CC and PipX) are out of flash space
so their stopwatch implementation has been swapped out for
one based on the DELAY clock that takes about 500 bytes less
of code space.

Identical functionality is preserved.

5f8760a55c com: Move buffering out of USART/HID layer and into COM layer
This allows the spektrum and sbus receiver drivers to bind
directly to the usart layer using a properly exported API
rather than overriding the interrupt handler.

Bytes are now pushed directly from the usart layer into the
com layer without any buffering.  The com layer performs all
of the buffering.

A further benefit from this approach is that we can put all
blocking/non-blocking behaviour into the COM layer and not
in the underlying drivers.

Misc related changes:
 - Remove obsolete .handler field from irq configs
 - Adapt all users of PIOS_COM_* functions to new API
 - Fixup callers of PIOS_USB_HID_Init()

df5569c758 Fix a stupid off-by-one that prevented this code from working.
Update to use 32-bit microsecond values.

Remove PIOS_DELAY_DiffuS per consensus (caller can do it easily themselves).

Update the core delay logic per Stac's suggestion to a version that is
resistant to various overflows.

6580462916 rcvr: specify drivers for groups of channels
Each channel was previously tracking a separate driver.
Now, channels are grouped within a channel group to save
RAM used for tracking and to better reflect how channels
are actually mapped.
