AMiRo-OS

AMiRo Modules: real-time capabilities analysed and timings set accordingly tight

Major overhaul of the shell.
A new configuration option allows to set the shell history length.

Makefile structure revised:
- Module specific tests nor come with individual makefiles, which include the general test code.
- Board configuration (e.g. connected breakout module) can now be set in Makefile or via CLI.

Merge branch 'master' into SSSPwoBLT

modified the structure of board.h and .c files to be consistent with ChibiOS

Shell is not implicitly enabled when tests are activated anymore.

Several fixed to the recent SSSP overhaul

Fixed a compatibility issue introduced by the recent modifications to the Makefiles

aosSysGetStdIntCallback() function renamed to aosSysGetStdExtiCallback()

Massive overhaul:
- updated to a new version of AMiRo-LLD
- tests (formerly unit tests) are now split onto multiple parts:
- there are "global" tests for each driver etc.
- there is an individual part for each module, e.g. if there are multiple instances of the same periphery...

Introduced optional CH_CFG_ST_TIMEDELTA definition per module.
If no value is specified by the module, a conservative fallback of 1000µs is set.

Updated to AMiRo-LLD 1.1:
- Implementation of periphAL has been modified accordingly.
- GPIOs are not encoded as port/pad tuple, but as lines
- Some unittests have been updated due to driver changes.

AMiRo-BLT and AMiRo-LLD updated as preparation for introduction of new AMiRo v1.2 modules.
fixed typos.

Default shell configurations have been changed:
Now the input line buffer can hold 128 characters (up from 64) and there can be up to 16 arguments per line (up from 4)

Enhanced the Makefiles to consistently use the BUIDDIR variable.

Fixed recently broken Makefiles (sry!)

ChibiOS updated to version stable_19.1.x.
NOTE: ChibiOS 19.1.x seems to contain some issues as of now.

Reordered some configuration files.
The BOARD_VERSION macro has been removed. Instead the version is now encoded in the other BOARD_XXX macros.

set the C standard to C17 (ISO), although this does not make any difference according to GCC documentation

updated AMiRo-LLD and applied all required changes to AMiRo-OS and all modules.

Enhanced the #include tree. 'amiroos.h' is now the central header, which includes all dependencies.

minor enhancements

Optimized the #include tree

Introduced a macro AOS_IOEVENT_FLAG() in aos_types.h.
This macro acts similar to EVENT_MASK() and should help to simplify development.
The new macro was applied to existing code wherever possible.

Added C++ system calls to the build toolchain in order to make AMiRo-OS fully compatible with C++ code.

Enhanced the main thread IO event configuration.
Therefore a new macro AMIROOS_CFG_MAIN_LOOP_IOEVENT_MASK has been introduced.

Removed modules/flash.mk since flashing procedures highly depend on hardware.

Introduced a switch to completely disable SSSP (thanks to S. Welzel)

Minor fixes and enhancements.

Removed the extension of the optional BUILDDIR variable in the module makefiles.

Some minor fixes and enhancements.
Most importantly, the expected jitter (CH_CFG_ST_TIMEDELTA) was increased form 20 to 50us.

All contents of the os/ folder has been moved one directory up.

Review of the QEI driver patch (minor changes).

add dw1000 unittest

Reintroduced ChibiOS patch for non-DMA I2C access.
Old patch could not be applied to latest version of ChibiOS anymore.

Major rework of the recent changes.
- optimized interrupt system (removed aos_interrupt.h/c)
- updated AMiRo-LLD submodule
- updated all config files to match the latest templates by ChibiOS
- fixed several issues regarding the new timer system (intervals)

Introduced an mechanism to measure clock skew during operation phase, if AMIROOS_CFG_PROFILE is enabled (non-master modules only).
The low-pass filtered skew is printed via the module:info shell command.

Introduced SSSP stage 3 of the startup phase (module stack initialization).

Introduced the capability to set and get a date&time value via the shell.

modified all relevant makefiles to adopt the new file structure
