BREAKING CHANGE: Convert the legacy STM32 F1/F2/F3/F4/G4/L1 port to the concrete
family selectors while keeping the shared STM32 selector hidden.
Legacy STM32 family selector Kconfig symbols were split by
concrete STM32 sub-family. Out-of-tree defconfigs and code must update
CONFIG_ARCH_CHIP_* selections to the new family-specific selectors.

When using FS_CROMFS for etc, user typically don't need FS_ROMFS,
they are completely separate filesystems. But both ETC_ROMFS and
ETC_CROMFS are needed, the first one selects that the ETC needs
to be mounted from ROM based filesystem, and ETC_CROMFS just specifies
that the backing filesystem is actually the CROMFS.

When config is NULL - driver behavior is the same as before.
With this change bme680 can be configured during registration in board logic.

This change makes the registration the same as for bme688, which is a similar

Some GCC-based external toolchains define **FLT_EVAL_METHOD** but do not
leave the standard FLT_EVAL_METHOD macro visible when the NuttX cmath shim
evaluates its guards.
As a result, C math symbols such as log and pow are declared by NuttX
math.h, but are not imported into namespace std by include/cxx/cmath.
Define FLT_EVAL_METHOD locally from **FLT_EVAL_METHOD** when needed in the
non-CONFIG_LIBM_TOOLCHAIN path.

The default sim:nsh config has no RTC, causing NSH_DISABLE_DATE to be
auto-enabled (default: DEFAULT_SMALL || !RTC). This means the date
command is not compiled in, and the system time defaults to a hardcoded

sim:nsh defconfig so the date command is available and shows the

Add NULL check for g_uart_devs[i] before accessing ->priv in
arm_earlyserialinit() loop. When a USART is not enabled in defconfig,
g_uart_devs[i] is NULL, causing a HardFault crash during early boot.
The bug occurs because the original code only checked g_uart_devs[i]->priv
without first verifying g_uart_devs[i] is not NULL. On Cortex-M4, NULL
pointer dereference reads from Flash vector table (0x00000000 maps to
0x08000000), returning a function pointer that causes BusFault when
written to.
This fix matches the existing NULL check pattern used in arm_serialinit()
at line 2835 of the same file.
Tested on mplant-gd32f450 board with only USART5 enabled in defconfig.
Before fix: HardFault at boot (IPSR=3, PC=0x080003e0)
After fix: System boots normally to NSH Shell

This adds 3 configuration options for the lib_strftime, which can be
used to save flash memory when all the formatters are not needed by an
embedded application.
There is always a minimal set of formatters supported:
"%a, %b/%h, %d, %H, %m, %M, %S, %Y, %%". To add on top of that one can
specify:
- LIBC_STRFTIME_C_STANDARD_FORMATS : All ISO-C conversion specifiers
- LIBC_STRFTIME_POSIX_FORMATS : Additional posix formats
- LIBC_STRFTIME_NONSTANDARD_FORMATS : Additional GNU nonstandard formats
All of these are enabled by default unless building for CONFIG_DEFAULT_SMALL.
Disabling these options can save over 3KB of flash on an 32-bit
ARM system, when all the format specifiers are not needed.

The previous up_backtrace() relied entirely on host_backtrace() (a thin
wrapper around glibc's backtrace()), which can only unwind the host
thread that calls it. As a result, when assert / dump_tasks() walked the
task list and called sched_dumpstack() for every task, every task other
than the currently-running one returned a zero-length backtrace, and the
output was silently dropped. In practice this meant that on sim only
the crashing task ever produced a usable trace.
Fix this by walking the frame-pointer chain ourselves whenever the
target tcb is not the running task. Because sim's setjmp/longjmp is
provided by NuttX itself (libs/libc/machine/sim/arch_setjmp_*.S) and not
by host libc, the rbp/rsp/rip (or arm fp/sp/pc) saved in tcb->xcp.regs
are plain unmangled pointers, identical across Linux, macOS and Windows
hosts. The frame layout ([fp]=prev fp, [fp+1]=return address) is also
shared by every host ABI sim supports (x86, x86_64, ARM, ARM64).
The walker validates that fp lies inside the task's stack and is
properly aligned, and stops when fp[0] is NULL, so a corrupted stack
cannot make us read out of bounds. The running-task path is unchanged
and still uses host_backtrace() so DWARF unwinding through host
libraries continues to work.
Requires CONFIG_FRAME_POINTER=y so the compiler emits a usable fp link.
