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

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
