Long long support is now unconditional in printf/scanf and related

libvsprintf/libvscanf/ultoa_invert, the build-time #error in the
rn2xx3 driver, and clean up CONFIG_LIBC_LONG_LONG entries from all

Every compiler supported by NuttX provides the "long long" types,
so the CONFIG_HAVE_LONG_LONG indirection is no longer useful.
Remove the option from include/nuttx/compiler.h and treat
"long long" as unconditionally available across the OS.
In addition to deleting the guard itself, this commit unconditionally
enables the long-long flavored helpers that used to be gated behind
it:
- libs/libc/fixedmath: drop the soft-emulated b32/ub32 routines
in lib_fixedmath.c (-261 lines) and trim the matching
prototypes, Make.defs and CMakeLists.txt entries; keep only
the long-long backed implementations.
- include/sys/endian.h, include/strings.h, libs/libc/string
/lib_ffsll.c, lib_flsll.c: always expose the 64-bit byte-swap
and ffsll/flsll variants.
- libs/libm/libm/lib_llround{,f,l}.c: drop the empty stubs.
- libs/libc/stdlib (atoll, llabs, lldiv, strtoll/ull, rand48,
strtold), libs/libc/stream (libvsprintf, libvscanf,
libbsprintf, ultoa_invert), libs/libc/misc (crc64, crc64emac),
libs/libc/inttypes/strtoimax, libs/libc/lzf, libs/libc/libc.csv,
libs/libc/string (memset, vikmemcpy): remove the
#ifdef CONFIG_HAVE_LONG_LONG branches.
- include/{stddef.h,stdlib.h,fixedmath.h,sys/epoll.h,cxx/cstdlib,
nuttx/audio/audio.h,nuttx/crc64.h,nuttx/lib/math.h,
nuttx/lib/math32.h,nuttx/lib/stdbit.h}: same guard cleanup.
- drivers/note/note_driver.c, fs/spiffs/src/spiffs.h,
sched/irq/irq_procfs.c: drop their local guards as well.
- Documentation/applications/netutils/ntpclient/index.rst:

BREAKING CHANGE: remove PWM_MULTICHAN option
PWM_MULTICHAN option is redundant, we can just set CONFIG_PWM_NCHANNELS > 1.
At default CONFIG_PWM_NCHANNELS is set to 1, so the default behavior is preserved.
Access to single channel API is now `info->channels[0].XXX` instead of `info->XXX`
This is the first step to simplify PWM implementation and make it more portable.

current_usec() returns a uint64_t, but it used TICK2USEC(timebase)
to convert scheduler ticks to microseconds. On 32-bit clock_t builds,
TICK2USEC() performs the multiplication in 32-bit arithmetic before the
result is widened.
With CONFIG_USEC_PER_TICK=10000, this wraps after about 71.6 minutes:
UINT32_MAX / 1000000 ~= 4294 seconds
After the wrap, up_timer_gettick() can report time near zero again. This
can leave absolute watchdog timeouts, such as those used by usleep() /
clock_nanosleep(), waiting for a tick value that will not be reached until
the 32-bit scheduler counter wraps.
Cast timebase to uint64_t before multiplying by USEC_PER_TICK so
current_usec() remains monotonic across the 32-bit microsecond boundary.

BREAKING: In an effort to simplify NuttX initialization, NSH_ARCHINIT is
removed. board_app_initialize is also removed. BOARD_LATE_INITIALIZE now
performs all board initialization logic, and is by default enabled. All
references to these symbols are removed. BOARDIOC_INIT remains, but will
result in -ENOTTY when called. It is to be removed in a later commit.
Quick fix: Boards relying on NSH_ARCHINIT should now enable
CONFIG_BOARD_LATE_INITIALIZE instead. If the application needs
fine-grained control over board initialization from userspace, the logic
performed by BOARDIOC_INIT may be copied to the board_finalinitialize
function and used instead via BOARDIOC_FINALINIT. All
board_app_initialize logic provided by NuttX is now moved to
board_late_initialize, and the same should be done for out-of-tree
boards.

Use the chip's built-in 20-entry non-volatile Bad Block Management
Look-Up Table (datasheet section 8.2.7) to transparently route around
bad blocks.
Init:
- Reserve the top 24 blocks of the array as a spare pool
- Clamp the MTD geometry to W25N_USER_BLOCKS = 1000 so upper layers
never see the spare area (125 MB usable instead of 128 MB)
- Force BUF=1 alongside enabling ECC. The W25N01GVxxIT variant
power-ups with BUF=0 (Continuous Read mode), in which Read Data
ignores the column address and always starts at byte 0 - which
silently broke any read targeting a non-zero column (OOB markers,
sub-page reads in w25n_read).
- Scan all 1024 blocks for factory bad markers (non-FFh at byte 0 of
the spare area of page 0) and remap any user-area bad blocks via the
A1h BBM command. Idempotent across reboots: blocks already present
in the LUT are skipped, so repeated scans don't consume LUT slots.
Runtime:
- On E-FAIL from w25n_block_erase or P-FAIL from w25n_program_execute,
allocate a spare and issue A1h, then retry the operation once. The
chip routes the retry to the spare PBA transparently. Data buffer is
reloaded on program retry.
- Uncorrectable read ECC is left as -EIO (soft errors shouldn't trigger
permanent remap, and remapping discards data we may still recover).
Safeguards against burning LUT slots on bogus bad blocks:
- w25n_pick_free_spare erases each candidate spare as an active proof
of life before returning it - the factory OOB marker alone isn't
trusted.
- w25n_bbm_swap rejects A1h with LBA outside the user area or PBA
outside the spare pool.
Stack discipline for the logger-thread hot path:
- The 20-entry cached LUT lives in the device struct, not on the stack.
- w25n_read_bbm_lut decodes 4 bytes at a time instead of reading the
full 80-byte LUT dump into a local buffer.
Boot diagnostics are emitted via syslog so they appear unconditionally:
- [w25n] BBM scan summary (new/remapped/unremapped/previously-remapped/
LUT slots used)
- [w25n] W25N01GV ready line with user blocks, spare count, geometry,
and actual SPI frequency
- [w25n] per-remap info and warnings on runtime E-FAIL/P-FAIL paths
Note: existing littlefs filesystems become unmountable because the
block count shrinks from 1024 to 1000; both PX4 board init.c paths
already mount with autoformat so they reformat on first boot after
this change.

If power down mode is set, trying to read ID ends in an infinite loop
because w25_waitwritecomplete never returns as status register never
signalizes write complete. Therefore ensure the device is not in a
power down mode before trying to read from it.
This can be an issue if the board is trying to check for more NOR
memories on one SPI bus and one chip select. For example GD25 driver
returns the memory to power down state after read id is finished,
therefore board initialization is stuck in an infinite loop if it first
checks for GD25 and then fallbacks to W25.
The commit fixes the possible issue by ensuring W25 is brought back
to normal operation mode before trying to obtain the manufacturer ID.

ftl_write() unconditionally routes writes through rwb_write() when
FTL_HAVE_RWBUFFER is defined, ignoring the O_DIRECT flag stored in
dev->oflags. This means callers that open with O_DIRECT expecting
unbuffered writes still get their data buffered in RAM.
The O_DIRECT flag is already checked in ftl_flush() to select
between direct and read-modify-write paths, but the buffering
decision in ftl_write() never consults it.
Add O_DIRECT checks in both ftl_write() and ftl_read() to bypass
rwbuffer entirely when the flag is set. For writes, go directly to
ftl_flush() and normalize the return value to match the block
driver convention (nsectors on success). For reads, go directly to
ftl_reload(), bypassing any read-ahead cache.
This gives O_DIRECT callers a complete bypass of the rwbuffer layer
for both reads and writes, matching the documented contract.
