* Add a migration warning to the update release system and the elf
programs documentation pages. This is just to add a papertrail from
where the documentation originate in case of error during the migration
process.
* Improve the building nuttx with app out of source tree
* Add new guide pages
* Building uclibc++
* Custom app directories
* Debugging ELF loadable modules
* Multiple NSH sessions
* NSH network link management
* RAM & ROM disks
* Reading CAN messages
* Remove device drivers with NSH
I think the guy who wants to port NuttX is expected to understand NuttX kernel code and related configurations,
but the getting enough knowledge needs to read the kernel codes deeply.
To reduce the time for NuttX beginner who wants to port,
I tried to make the guide (how to port) based on my porting journey.
This commit adds documentation for compiling NuttX for pysimCoder and
then running pysimCoder designed applications on NuttX. PysimCoder is
a Rapid Control Application Development Tool that can transfer block
diagrams into C code and can be used in real time control applications.
