- migrated /README are removed from /boards
- there are a lot of READMEs that should be further converted to rst.
At the moment they are moved to Documentation/platforms and included in rst files
When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)).
The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used.

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

* boards/arm/tiva/tm4c129e-launchpad/README.txt:
Expand this documentation with information about: toolchains,
debugging (including the elusive openocd incantation to flash program
the board), MCU clocking, more details about the Virtual COM port
exposed via ICDI, and a description of the recently added ostest
configuration.
* boards/arm/tiva/tm4c129e-launchpad: New subdirectory providing
board support for the Texas Instruments TM4C Crypto Connected
LaunchPad, or more correctly the EK-TM4C129EXL.
* Documentation/introduction/detailed_support.rst,
Documentation/introduction/supported_platforms.rst,
boards/README.txt: Document the additional board support.
* boards/Kconfig:
(ARCH_BOARD_TM4C129E_LAUNCHPAD): New config.
(ARCH_BOARD): Add tm4c129e-launchpad.
(Board-Specific Options): Source the board-specific Kconfig
boards/arm/tiva/tm4c129e-launchpad/Kconfig when selected.
Summary:
- I noticed that error happens in loading nettest elf application.
- This commit fixes this issue by adding SYMTAB to the NSH
as well as adjusting some parameters in CONFIG_ELF_XXX
- Also, CONFIG_EXAMPLES_HELLO is changed from y to m for testing.
Impact:
- lm3s6965-ek:qemu-protected only
Tested:
- Tested with qemu-6.2

Summary:
- The configuration is no longer needed because Kconfig has
been fixed in the previous commit
Impact:
- None
Testing:
- Tested with QEMU
