The maximum number of missions was increased in almost 8 times in
recent commit: 9369262e63 navigator: allow more mission items.
As this board loads missions in RAM, now it don't have enough memory
to allocate causing dataman start to fail, so mark it as a memory
constrained system and reduce the number of maximum missions
supported.
We need to protect access to the param_values array. This is dynamically
allocated and resized (utarray_reserve() calls realloc). If some thread
was iterating the array while another was resizing the array, the first one
would iterate on a freed array, thus accessing invalid memory.
On NuttX this could lead to hardfaults in rare conditions.
Unfortunately we need to initialize the semaphore on startup, by calling
sem_init(). This adds a param_init() method called by every board/config
that uses the params (at least I think I've found all of them)
From their registers it's not possible to differentiate MS5611 from
MS5607. Here we use a little heuristic that people won't likely be
flying (or starting to fly) on very high altitude, greater than 5300m.
Even on these altitudes the error would be much lower using the MS5611
calculations for MS5607 than it is on MSL.
Remove the notion of legacy from the api. The board level code
will perform the traslation to lecacy format on the STM32.
new targets will not need to do this as there is no case
where the serial number were used by mfg for tracking.
Extend board common api to get mfguid and mfguid formatted
This adds an api that return the MFGUID as an array of bytes
or a string.
The data is returned with the MSD at index 0 and the LSD at
index PX4_CPU_MFGUID_BYTE_LENGTH-1.
Removed all reodering defines from the api and hal
Fixes the following case: a board that has several bus_options enabled,
and wants to start a specific device (eg mpu6000 -T 20608 start). In that
case the given device_type is never actually checked, and since the start
routine iterates over all bus_options, several can match, and thus start
multiple instances of the driver (note that the whoami check is performed
against the value provided with -T and thus the check will pass).
This happens on Pixracer (PX4_SPIDEV_MPU and PX4_SPIDEV_ICM_20608 are both
set).
