The lower-half implementation of the RMT character driver based on
Espressif HAL enables using the RMT peripheral of ESP32, ESP32-S2
and ESP32-S3 as a common xtensa-based Espressif driver.
The RMT packages on Espressif SoCs are 4-byte long and are known as
"items". Please check the Techinal Reference Manual of the chip to
obtain more details.
When the user selects the debug features it will enable
the Debug Errors, Warning and Info by default avoiding
the issue: https://github.com/apache/nuttx/issues/10452
User still need to enable individual debug for each
subsystem, so this patch didn't increase binary size.
Allows the debug behavior to be specified as part of the board, architecture or chip configuration. This is useful when using out-of tree custom board configurations.
Port based on arch/arm/nrf53.
Modem not fully supported yet. At the moment, initialization and AT interface work.
Sockets and GNSS interface will be added later.
This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size
Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

This commit aims to provide a way to get the current applied defconfig on runtime by providing CONFIG_BASE_DEFCONFIG that is updated when the configure and build scripts are run.
when using the clock_gettime() function to print the timestamp, the sinfo() function is called, as same as syslog(). But syslog() itself has the ability to print a timestamp, and called clock_gettime(). Thus, the clock_gettime() and syslog() have a recursive call problem. In order to solve this problem, it is necessary to ensure that SYSLOG_TIMESTAMP is close when DEBUG_SCHED is open.

First decoupling changes related to CMAKE
BINDIR/APPSBINDIR:
Output path of Kconfig which dynamically generated by NuttX Kernel/Apps
This option is consistent with the TOPDIR/APPSDIR by default, and will
be changed when out-of-tree compilation is supported

Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld
when linking NuttX ELF. That file can be useful for verifying
and debugging magic section games, and for seeing which
pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS.

Enable this option to optimization the unused input sections with the
linker by compiling with " -ffunction-sections -fdata-sections ", and
linking with " --gc-sections ".
