Shmem region lives in RAM and should not be load in FLASH.
This fixes the issue with wrong binary size when build AMP
configurations with RPTUN enabled. Before this change shmem
region was exported by objcopy to binary file which caused
the bin size to be huge and impossible to flash.

Add new RISC-V 64-bit QEMU configuration with:
- 64-bit RISC-V (RV64) architecture support
- RISC-V Vector Extension (RVV/V-extension) enabled
- LVGL graphics framework integration
- VirtIO GPU and input device support
- NSH shell with built-in applications
This configuration enables developers to build and test LVGL graphical
applications on 64-bit RISC-V targets with Vector extension support,
providing a foundation for future SIMD optimization work.
Includes:
- defconfig: Complete configuration file with all necessary options
- Updated index.rst: Build and run instructions with QEMU launch command

Add support for the QMI8658 6-axis IMU sensor (accelerometer + gyroscope)
on the lckfb-szpi-esp32s3 board.
Changes:
- New esp32s3_qmi8658.c driver initializes sensor on I2C0 at address 0x6A
- Registers uORB devices: /dev/uorb/sensor_accel0 and /dev/uorb/sensor_gyro0
- Adds esp32s3_qmi8658_initialize() function declaration to header
- Integrates with board bringup when CONFIG_SENSORS_QMI8658=y

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 change makes the esp32c3-generic the main esp32c3 supported board: esp32c3-devkit.
The now esp32c3-legacy is pure register based and not maintained anymore.
Now, esp32c3-devkit shares the same driver implementation as ESP32-C6 and ESP32-H2.
- esp32c3-devkit -> esp32c3-legacy
- esp32c3-generic -> esp32c3-devkit

This defconfig uses the legacy bootloader (based on ESP-IDF's

Fix a transfer issue in the Kinetis DSPI driver when operating
with transmit and receive FIFOs disabled (`MCR[DIS_TXF]=1`,
`MCR[DIS_RXF]=1`). In this mode, the DSPI module behaves as a
simple double-buffered SPI interface without TX staging.
When FIFOs are disabled, `PUSHR` acts as a single 32-bit
command/data register. Partial (16-bit) writes to its upper or
lower halves can result in incomplete or corrupted transfers.
This patch ensures the full 32-bit packet is prepared and
written in a single operation.
* Resolves broken SPI transactions with LAN9252 (EasyCAT).
* Improves reliability in non-FIFO DSPI configurations.
* No impact on DMA or FIFO-enabled modes.
