Add support for the GalaxyCore GC0308 VGA CMOS image sensor.
The driver implements the NuttX imgsensor interface and supports
VGA (640x480), QVGA (320x240), and QQVGA (160x120) resolutions
via Kconfig selection. Output format is RGB565X (big-endian).

Add big-endian RGB565 (RGB565X) pixel format throughout the V4L2
video pipeline:
- IMGDATA_PIX_FMT_RGB565X in imgdata.h
- IMGSENSOR_PIX_FMT_RGB565X in imgsensor.h
- Format conversion and buffer size handling in v4l2_cap.c
This is needed by 8-bit DVP camera sensors that output RGB565 in
big-endian byte order (high byte first on the data bus).

Add sysctl driver for K210 SoC providing clock and reset control:
- Clock enable/disable with two-stage APB/peripheral enable pattern
- Peripheral reset control with proper timing
- Clock frequency query for PLL, CPU, APB buses, and peripherals
- PLL frequency calculation and CPU frequency configuration
The sysctl driver is built unconditionally for K210 boards as it
provides essential clock and reset control functionality.
Add Kconfig option:
- K210_CPU_FREQ: Target CPU frequency in Hz (default 400MHz)

This patch introduces CONFIG_CC1101_SPIFREQ_BURST and
CONFIG_CC1101_SPIFREQ_SINGLE to Kconfig, allowing users to override
the default SPI frequencies for the CC1101 wireless driver.
Previously, these values were hardcoded to 6.5 MHz and 9.0 MHz
respectively. While these are safe defaults for many setups, specific
hardware designs, high routing capacitance, or platforms utilizing
internal GPIO switching matrices (such as the ESP32) can suffer from
signal integrity degradation at these speeds. By exposing these to
Kconfig, users can easily adjust the clock speeds to match their
hardware capabilities without modifying the core driver source.
Impact:
- Build: Adds two new Kconfig options under WL_CC1101.
- Runtime: Retains 6.5 MHz / 9.0 MHz defaults. Behavior only changes
if overridden via menuconfig.
Testing:
- Built with default values and custom Kconfig overrides.
- Hardware Testing: Tested on a sub-optimal platform utilizing an
internal GPIO matrix (ESP32). The CC1101 failed to load at the
default 6.5/9.0 MHz due to signal integrity issues. Downclocking
the frequencies to 4.0 MHz via Kconfig successfully restored
signal integrity and allowed the driver to initialize and operate
normally.

Add nxboot bootloader board integration for nucleo-h743zi.
nxboot uses a three-slot layout (primary, secondary, tertiary) with
no scratch partition.
- add STM32_APP_FORMAT_NXBOOT board support and nxboot-specific OTA
slot defaults
- gate scratch partition configuration on MCUboot, where it applies
- select nxboot linker scripts in the board build logic
- add tertiary OTA partition support in stm32_progmem.c
- add nxboot-loader and nxboot-app defconfigs and linker scripts
- validate the fixed nxboot flash layout used by this board so
mismatched config values fail at build time instead of producing
a silently broken image

This PR addresses several portability and technical debt issues in the mnemofs filesystem by resolving source-level TODO items.
Changes:
- Implemented a portable fallback for mfs\_clz (Count Leading Zeros) in fs/mnemofs/mnemofs.h using a binary search approach. This ensures compatibility with non-GCC compilers.
- Removed the redundant 8-bit mfs\_arrhash and consolidated hashing with the existing 16-bit mfs\_hash in mnemofs\_util.c.
- Removed the related TODO comments in mnemofs.h and mnemofs\_util.c.
- Fixed NuttX style (indentation and braces) in the fallback bit primitives.

This commit overhauls the CC1101 RF driver to address physical hardware
constraints, prevent register wrap-around overflows, and support accurate
dBm power scaling via the standard IOCTL interface.
What this change does:
1. Adds WLIOC_MSK and WLIOC_4FSK modulation support in `ioctl.h` and driver.
2. Replaces static PATABLE initialization with a dynamic Ramp-up curve
generator `cc1101_ioctl_apply_power()` based on lab calibration data.
3. Modifies WLIOC_SETTXPOWER and WLIOC_GETTXPOWER to process actual dBm
values with a nearest-match algorithm instead of raw array indices.
4. Removes DEBUGASSERT on user-space IOCTL pointers and replaces them
with strict -EFAULT checks.
5. Implements saturation clamping (e.g., mantissa to 256-511) to prevent
bitrate and frequency deviation calculation overflows.
6. Rebuilds volatile PATABLE memory upon SLEEP mode wake-up.
Why it is necessary & what it fixes:
- Fixes severe OOK modulation distortion and FSK spectral splatter caused
by statically assigned PATABLE indices.
- Fixes potential kernel panic in flat builds when IOCTL receives a NULL
pointer from user space.
- Fixes register wrap-around (silent failures) when users pass
out-of-bounds baud rate or FDEV values.
- Prevents RF silence after SLEEP mode due to PATABLE volatility.
- Resolves inaccurate power output when changing frequencies dynamically.
Impact:
Changes the behavior of CC1101 TX power and modulation IOCTLs to strictly
comply with standard `wlioc` definitions. Improves overall driver stability
and hardware safety.

Three fixes to make LPUART1 work as NSH console on Nucleo-L552ZE-Q:
1. stm32l5_lowputc: add LPUART-specific BRR formula (256 * fCK / baud)
instead of reusing the standard USART divisor calculation.
2. stm32_boot: enable VDDIO2 and reconfigure LPUART1 GPIOs (PG7/PG8)
in board_initialize. The low-level setup runs before VDDIO2 is
enabled, so GPIOG writes silently fail.
3. stm32l5_serial: fix LPUART1 apbclock (PCLK1 not PCLK2), add
LPUART BRR branch in setformat, cast to uint64_t to prevent
32-bit overflow in (fCK << 8).
Also switch nsh defconfig from USART3 to LPUART1, add GPIO_LPUART1
pin definitions in board.h, and update board documentation.

This commit refactors the CC1101 driver's read interface to comply with
the standard NuttX wireless character driver API and introduces extended
hardware operation modes.
- Migrate `cc1101_file_read` to accept and populate the standard
`struct wlioc_rx_hdr_s` instead of returning raw byte arrays.
- Implement `cc1101_calc_rssi_dbm_x100` to preserve the hardware's
0.5 dBm RSSI precision when scaling to 1/100 dBm units, eliminating
the integer truncation loss present in the legacy calculation.
- Add `CC1101IOC_SETOPMODE` and `CC1101IOC_GETOPMODE` IOCTLs.
- Introduce four RF operation modes (`enum cc1101_opmode_e`):
1. NORMAL: Standard packet mode with hardware filtering.
2. PROMISCUOUS: Packet mode bypassing address filtering and retaining
packets with CRC errors.
3. SYNC_SERIAL: Bypasses FIFO, routes clock and data to GDO0/GDO2.
4. ASYNC_SERIAL: Bypasses FIFO, routes async data to GDO2.
- Fix the `GS2200M_FIRST` IOCTL block offset in `wireless/ioctl.h` and
allocate a dedicated IOCTL block for CC1101.
