It seems libcxx needs C++20 from 12.0.0 to 17.0.6: 3b625060fc
But we're setting CMAKE_CXX_STANDARD to 17, errors on my side:

This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"

new options to enable toolchain support for quadruple precision
(128 bits or 16 bytes) floating point if both the toolchain and
the hardware support it.

Task activation/exit logs are helpful for device bringup,
especially when user space nsh prompt doesn't show up.
Putting them here will allow cleaning of logs in multiple
up_exit() functions later.

Some devices have special preparations before entering S-mode, thus
a hook is needed from NUTTSBI to give them the chance.

Chips like K230 has ARCH_RV64 but only supports 32-bit MMIO. So using
ARCH_RV_MMIO_BITS is more proper here.

This is not the right place to modify DMA memory protection values.
Why not? These are designed to protect other AMP mode instances. Opening
the entire SoC's memory for the USB DMA kind of defeats this purpose.
Also, the driver cannot know how to configure these registers correctly,
only opening up the whole SoC "works".

Fully linked apps take less storage and are efficient to load. This
is to enable them for rv-vrit configurations in KERNEL build.
Changes:
- arch/risc-v/Kconfig select BINFMT_ELF_EXECUTABLE for QEMU-RV
- boards/risc-v/qemu-rv/rv-virt/configs
- knsh32/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- ksmp64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knetnsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knetnsh64_smp/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
Additions:
- boards/risc-v/qemu-rv/rv-virt/scripts/
- gnu-elf.ld apps linker script
The ARCH_TEXT_VBASE of knsh32 is set to same as that of 64bit to reuse
the apps linker script.

Previously apps in kernel build are partially linked, thus are
big and inefficient. This enables full link for kernel mode apps
to reduce size and speed up loading.
Changes:
- arch/risc-v/Kconfig select HAVE_ELF_EXECUTABLE for K230
- boards/../scripts/Make.defs adjust LDELFLAGS
- boards/../knsh/defconfig enable BINFMT_ELF_EXECUTABLE
Additions:
- boards/../scripts/gnu-elf.ld apps linker script

The RT-Timer thread may call the `start_rt_timer` function. This
function gets the spinlock with interrupts disabled to ensure
exclusive access. However, this was already being performed in the
RT-Timer thread, causing a deadlock.
Following up the 'Espressif HAL fullly integration for ESP32s2/s3'
changes in https://github.com/apache/nuttx/pull/11428
There are few missing interrupt type constants need update. So
update them to avoid the build error.
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.
