Julian Oes 9595f12327 holybro: fixup Wing system power setup
I don't think we have a way to explicitly detect if BAT1 or BAT2
"bricks" are correct, so we have to assume they are, and rely on the
voltage/current shown.

Additionally, we can now power cycle sensor power.

Julian Oes 56eb9bcc18 mavsdk_tests: workaround race condition
PX4 needs a bit of time to process an uploaded mission before it is
ready to accept the mission mode.

Therefore, we need to wait a bit.

Alternatively, we could wait on the mission progress arriving properly,
but this sleep is simple enough for now.

Julian Oes 3c39095271 [Sponsored by Holybro] Support for Kakute H743-Wing (#24669)
* hrt: Fix PPM input on channel 2

The CCMR1_PPM define for PPM input on channel 2 was incorrectly set to 2,
which was setting bits for channel 1 instead of channel 2. This prevented
PPM input from functioning properly on channel 2.

Changed CCMR1_PPM for channel 2 from 2 to (1 << 8), which correctly
configures the CC2S bits for input capture mode on TI2.

This fixes an issue noted in the existing code comment:
"FIXME! There is an interaction in the CCMR registers that prevents
using Chan 1 as the timer and chan 2 as the PPM"

Tested on STM32H743 with PPM input on PC7 (TIM8_CH2).

* rc_input: enable sharing serial and PPM pin

By setting RC_SERIAL_PORT_SHARED_PPM_PIN_GPIO_RX it is now possible to
use the same pin on the STM32 for PPM input as well as serial input.

Julian Oes a9214b3aa3 gimbal: don't spoof gimbal device (#24271)
The current approach was wrong because the gimbal protocol now

non-MAVLink gimbal.

This means that we don't need to send message "as if we were a gimbal
device" and instead set thet gimbal_device_id to 1 (up to 6) to indicate
we are in charge or a non-MAVLink gimbal.

I therefore suggest to disable the on device IIR filter which makes the

We should not send out acks for commands that are not targetted at us.

This was likely introduced to debug when MAVLink components were
implemented incorrectly sending commands to a wrong target.

Julian Oes 3710a9ef6e gimbal: fix auto RC and MAVLink mode
This fixes various edge cases when input is set to both: RC and
MAVLink gimbal protocol v2.

Specifically:
- We no longer immediately reset primary control if there is no update,
  otherwise this will reset immediately after an commands.
- Talking of commands: GIMBAL_MANAGER_CONFIGURE no longer switches
  control to MAVLink but only an actual incoming setpoint command does.
- And incoming setpoint command only triggers UpdatedActiveOnce which
  means we will check RC again afterwards and if there is big movement
  switch back to RC. That's the intuitive thing to do until we have
  better reporting about who/what is in control.
- Also, with RC we no longer always set us to be in control but only on
  major movement.

Julian Oes 7c4507b6d6 bootloader: add bootloader version
This adds a new protocol extension which allows to get the bootloader
version.

The bootloader version is different from the bootloader protocol
revision which has stabilized at 5 and is not easy to update unless a
bootloader is actually breaking the protocol. The reason being that both
the Python script as well as the uploader used in QGC will not attempt
to load firmware if they don't know the bootloader version, so it could
basically be considered a "breaking" protocol revision.

Julian Oes 21e550fdba tools/bootloader: add force-erase option
If the STM32H7 fails to program or erase a full chunk of 256 bytes, the
ECC check will trigger a busfault when trying to read from it.

To speed up erasing and optimize wear, we read before erasing to check
if it actually needs erasing. That's when a busfault happens and the
erase time outs.

The workaround is to add an option to do a full erase without check.

Credit goes to:
https://github.com/ArduPilot/ardupilot/pull/22090

And the protocol option added to the bootloader is the same as for
ArduPilot, so compatible.

Julian Oes 19964d56ed fmu-6x: Use i2c_launcher by default
This switches all SENS_EN_INAXXX params to 0 by default and instead uses
the i2c_launcher command.

However, if any one the SENS_EN_INAXXX param is set, it no longer tries
to auto-configure it.

this fix is absolutely required.

Julian Oes 19b681ca1f Remove SYS_USE_IO param
The param is not really required anymore with the actuator
configuration. Also, when it is set to 0, RC doesn't work for some
boards which would be nice to avoid.

Julian Oes fefdad83bf mavlink: fix MAVLink message forwarding
This switches from the horribly intertwined ringbuffer implementation to
the new VariableLengthRingbuffer implementation.

By ditching the previous implementation, we fix MAVLink message
forwarding, which didn't work reliably. The reason it didn't work is
that multiple mavlink messages could be added but only one of them was
sent out because the buffer didn't keep track of the messages properly
and only read the first one.
