we can mount a zipfile in nuttx use mount command like this:
mount -t zipfs -o /data/test.zip /zip
The zipfs is a read only file system,The advantage is that it
does not occupy additional space when reading the decompressed file.
When used, reading and decompression operations are simultaneous.
The known disadvantage is that when using seek to read forward,
it will reopen and cause slow speed problems.

To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system. Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.
Revert this PR to ensure the compilation speed during incremental compilation.
| commit 34b34e2d45 (tag: nuttx-20200914-172150)

| Fix: ensure archive files do not carry object files from prior builds
|
| In some cases, when NuttX configuration changes and this makes the
| object list used to build one of the .a libraries change as well,
| since the command used to build it is "ar crs" and this simply appends
| the list of object files, the library could still include object
| files from prior builds. This commit modifies the ARCHIVE macro to
| erase the .a file if it already exists.
|
| Since in some cases this behavior was actually expected (object
| files from a subdirectory were appended to a library created one
| level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
| This change should greatly improve behavior of building after
| configuration changes.

Instead of setting kernel/user space instruction and data ROM as
hard-coded values on linker, set them according to the max size
of the kernel image set by CONFIG_ESP32S3_KERNEL_IMAGE_SIZE. This
is done by making KIROM, UIROM, KDROM and UDROM dependent on the
kernel size value. Also, override CONFIG_NUTTX_USERSPACE config
according to CONFIG_ESP32S3_KERNEL_IMAGE_SIZE by using a custom
PREBUILD definition.
Add PREBUILD definition and `prebuild` recipe to call it before
the `mkconfig` tool, at the beginning of the build process. This
`prebuild` step enables running CPU/board-specific operations
before building the firmware, like tweaking or overriding configs
that need to be set after the board configuration.
support arch:
sim x86
sim x86_64
arm32 all series
If we need to support more architectures in the future,
just add the 'g_tcbinfo' of the corresponding architecture
support thread command:
1. thread <id>
switch thread
2. info thread
list all thread info
3. thread apply [all | id list] command
like this:
thread apply all bt
thread apply all bt full
thread apply 1 2 4 bt
thread apply all info r
4. nxsetregs
Set registers to the specified values.
Usage: nxsetregs [regs]
Etc: nxsetregs
nxsetregs g_current_regs[0]
nxsetregs tcb->xcp.regs
Nxsetregs g_pidhash[0].tcb->xcp.regs
Default regs is g_current_regs[0],if regs is NULL,
it will not set registers.
Because NuttX enters exception_common during a crash,
this assembly function manipulates the stack pointer (sp),
causing GDB to be unable to trace back to the first context of the crash.
Instead, it shows the context of the interrupt stack. By using nxsetregs,
it is possible to forcefully set the first context to
the one before the interrupt occurred.
Notice:
Switching threads is achieved by setting registers,
so registers need to be restored before continue,
please use 'c' to continue instead of 'continue'

according to https://github.com/apache/nuttx/pull/7903
it was to fix "the macOS runners occasionally failing".
cython issue workaround seems more important because it always fails.
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

The following warning is emitted when building with GCC 12.2.0:
"the comparison will always evaluate as ‘true’ for the address of ‘g_parm’ will never be NULL [-Waddress]"
As g_param is an array of char[]. each member should have an actual address, so the validation in each if statement is not required.
Allows boards to supply their own gnu-elf linker script, used when building Nuttx applications and CONFIG_BUILD_KERNEL.
This is useful when building fully-linked applications (see #9395).
This patch add an example and pyhton base modules:
1.add memdump.py is an example to analyze memory
usage by python script.
2.add The most basic data structure analysis, like list, etc.

Maybe we can add modules related to "sched, drivers, arch, fs.." to
automatically analyze scripts to debug some problems

Currently when we modify some Kconfig related to some chip or
some architecture we need to run refresh.sh to all boards that
is too slow (more than one hour to finish).
This patch modify the script to update only the boards configs
of an specific chip or only the boards of an specific architecture.
Examples:
$ ./tools/refresh.sh --silent --defaults arch:renesas
Normalize us7032evb1/ostest
Normalize us7032evb1/nsh
Normalize skp16c26/ostest
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates the boards from all 'renesas' architecture (m9c, rx65n, sh1)
$ ./tools/refresh.sh --silent --defaults chip:rx65n
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates all the boards from renesas chip 'rx65n' family
The syntax check of kconfiglib is stricter than kconfig-frontends,
but the warnings of kconfiglib are not catched by Makefile. Since kconfiglib

whether the kconfig warning is occurred
