since the current txnotify is executed synchronously at the location of
the current call without switching threads, resources such as d_iob need
to be cached first.

This allows the compiler to automatically identify which string functions
can be compiled into libraries, and the compiler's internal implementation
is faster than libc functions.

Add MTD driver for Winbond W25N series SPI NAND flash.
Currently supports W25N01GV (1Gbit/128MB).
Features:
- Standard SPI interface with configurable frequency (up to 104 MHz)
- Hardware ECC enabled by default
- Block erase with sleep-based wait (releases SPI bus)
- Page read/write with busy-wait for fast operations
Limitations:
- No bad block management (BBM). Factory bad blocks and runtime bad
blocks are not tracked.
- No bad block table (BBT) scanning at initialization.
- No Quad SPI support (standard SPI only).
- No access to spare area (64 bytes/page) or OTP region.
Tested using:
- Board with STM32H743
- W25N01GV on SPI at 96 MHz with DMA enabled
- Flash mounted using littlefs
- Tested using sdbench:
- Sequential write speed of 1760 KB/s
- Sequential read speed of 4900 KB/s

The -D_FILE_OFFSET_BITS=64 parameter is missing
during the CMake compilation of the sim (simulator) build,
which causes incorrect version invocations of interfaces
such as hostfs_stat.

Add a safe synchronous hrtimer cancel API, hrtimer_cancel_sync().
If the timer callback is currently executing, this function waits
until the callback has completed and the timer state transitions
to HRTIMER_STATE_INACTIVE.

Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
NuttX provides the wdog module to implement timers for the scheduler.
While it is lightweight and efficient, wdog only supports tick-level timers,
typically in milliseconds. Although the tick duration can be configured,
setting it to microsecond or nanosecond resolution is not practical.
Doing so may cause an interrupt storm, where the CPU is constantly
occupied handling tick interrupts.
To address this limitation, a new hrtimer module is introduced.
It coexists with the wdog module, providing both tick-level timers
for wdog and high-resolution timers (nanosecond-level) directly to users.

This script downloads all NuttX RTOS and Application snapshot packages
from the upstream git repository based on the provided git tags list.
These are NOT official release packages as checkum will differ.
When launched from the local NuttX git repository clone the script will
obtain all available tags to be downloaded, otherwise list of tags needs
to be provided manually (or when just selected tag is required).
This script uses ``wget`` underneath, make sure this tool is installed.
Fetch log file is created with a timestamp in name next to the packages.
Having all tags packaged is important for changes comparison
between specific versions, testing a specific version, compatibility
checks, searching for a feature introduction timeline, etc.
Usage: `./nxtagspkgsfetch.sh [download_path] [tags_list_space_separated]`
You can provide optional download path (default `../../nuttx-packages`)
and tags list to get packages for (default all tags from local git clone).
When providing tags you also need to provide download path.
Documentation update contains new tool description (above).
