Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be mounted by Nsh.
etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.
But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.
changes:
- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
in boards, and no need declaration for romfs_img/romfs_img_len.
This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:
- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
in board/arch/board/board/src.

changes:
- under boards/risc-v/k230/canmv230/scripts/:
- Make.defs add POSTBUILD actions
- ld-flat.script minor reformating
- ld-kernel.script minor reformating
- under boards/risc-v/k230/canmv230/src/:
- Makefile add clean of generated ROMFS source
- canmv_init.c use `ferr` and drop too late runtime warning
- romfs_stub.c use const for romfs_img_len
The POSTBULD actions can warn stub ROMFS usage at build time, thus
the too late warning in canmv_init.c can be removed.
The cleaning of `libboard.a` in POSTBUILD can also ensure real ROMFS
is in use, as some times weak_data is still in use.

By integrating the Espressif`s HAL repository into the current
ESP32-S2 implementation on NuttX, it is possible to call functions
that makes it easier to setup the registers of the ESP32-S2,
enabling the usage of common Espressif drivers.
By integrating the Espressif`s HAL repository into the current
ESP32-S3 implementation on NuttX, it is possible to call functions
that make it easier to set up the registers of the ESP32-S3 and
enables the usage of common Espressif drivers. Please note that
Espressif's HAL repository was already being used for the Wi-Fi
driver. Then, this commit includes other source files to be used
by other drivers other than Wi-Fi and reorganize the build process.
The RMT (Remote Control) character driver allows to use the RMT
peripheral (usually, a one-wire peripheral dedicated to driving
IR remote control) as a character driver.
Please note that this perpiheral depends on the lower-half specific
driver implementation.

Once these messages are thrown during the system's bring-up, it is
advisable them to be output by the syslog considering the file
system initialization.
The SmartFS partition needs to be formatted before being mounted.
Otherwise, it would throw an error message. The error message now
contains a suggestion to format the partition when such an error
is detected.
The code is mainly derived from the NuttX qemu-rv/rv-virt codebase.
Major changes:
- boards/Kconfig: add new BOARD_K230_CANMV
- arch/risc-v/Kconfig: add new CHIP_K230 chip and ARCH_RV_MMIO_BITS
- arch/risc-v/src/common/riscv_mtimer.c: use ARCH_RV_MMIO_BITS to
select MMIO access width
New additions:
- arch/risc-v/include/k230/: k230 SoC definitions
- arch/risc-v/src/k230/: k230 SoC sources
- boards/risc-v/k230/canmv230/: CanMV-K230 board sources and configs
- Documentation/platforms/risc-v/k230/: simple doc
Note that only FLAT build works for canmv230 now.
This PR has changes in RiscV common layer thus may affect other RiscV ports
It changes the mtime/mtimecmp access control from using config ARCH_RV64 to
newly intorduced config ARCH_RV_MMIO_BITS.
Original design uses ARCH_RV64 to select 64bit MMIO in riscv_mtimer.c, this
can't cope with the situation with K230 --- it has ARCH_RV64 but only can do
32bit MMIO. So a new ARCH_RV_MMIO_BITS config has been introduced. Its value
depicts the MMIO width in bits. The MMIO_BITS defaults to 32/64 for RV32/
RV64 respectively. This allows the macro to replace current use of ARCH_RV64
in riscv_mtimer.c.
The new MMIO_BITS config is a derived one, and for RiscV chips with
equal CPU and MMIO widths there is no need to explicitly set it as the
default rule will do that. Only chips with different CPU and MMIO widths
need set it in Kconfig.
So by design this change should be safe but RiscV ports should be checked.
"ostest" verification has been done for:
- canmv230/nsh
- rv-vivt/nsh
- rv-virt/nsh64
configuration generation and manual check of derived RV_MMIO_BITS has been
done for:
- star64/nsh
- arty_a7/nsh
- bl602evb/nsh

Add registration function instrumentation API,
which can achieve instrumentation of entering and
exiting functions through the compiler's functionality.
We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all
source, or add '-finstrument-functions' to CFLAGS for Part of the
source.
Notice:
1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function,
becuase bss not set.
2. Make sure your callbacks are not instrumented recursively.
use instrument_register to register entry function and exit function.
They will be called by the instrumented function
