Add an RP23xx hardware crypto driver for /dev/crypto with SHA-256
support backed by the RP2350 SHA accelerator.
Wire the new driver into the RP23xx ARM build and register
CRYPTO_SHA2_256 through cryptodev.
Also fix the RP23xx SHA256 CSR BSWAP bit definition in both the ARM and
RISC-V RP23xx headers. The previous value used bit 18, but the RP2350
hardware uses bit 12. Without this fix, the accelerator hashed input
words with the wrong byte order and produced incorrect digests.

Implement imgdata_ops alloc/free callbacks so the V4L2 framework
can use MMAP mode to allocate frame buffers with proper GDMA
alignment. This lets applications avoid hardcoding platform-
specific alignment values.
- Add esp32s3_cam_alloc() using kmm_memalign with the alignment
derived from the GDMA external memory block size setting.
- Add esp32s3_cam_free() wrapper around kmm_free.
- Introduce ESP32S3_CAM_EXT_MEMBLK / ESP32S3_CAM_DMA_ALIGN macros
so the block size enum and byte alignment are defined in one
place and stay in sync automatically.

Fix several issues in the ESP32-S3 CAM driver:
- stop_capture: reset DMA channel, CAM module and AFIFO under
spinlock to fully quiesce hardware before returning. Clear
pending VSYNC interrupt to prevent stale ISR firing.
- uninit: reset CAM/AFIFO before releasing DMA to prevent
in-flight transfers after channel detach. Use esp_teardown_irq
with correct peripheral ID (ESP32S3_PERIPH_LCD_CAM) instead of
irq_detach which corrupts the shared IRQ mapping table. Mask
interrupts and clear pending flags under spinlock before
detaching handler.
- uninit: preserve XCLK output so the sensor remains accessible
via I2C for subsequent re-initialization.
- set_buf/uninit: track driver-allocated vs user-provided frame
buffers with fb_allocated flag to prevent double-free when
using V4L2 USERPTR mode.

Protect the common Espressif Wi-Fi netdev RX queue with a spinlock. The Wi-Fi RX callback enqueues packets while the netdev upper-half RX thread dequeues them, and the IOB queue helpers are not internally serialized.
Under sustained receive traffic that race can corrupt the queue state, strand IOBs, and degrade throughput over time as reported in issue #16915.
Initialize the lock during device setup and use it when clearing the queue on ifup, enqueueing received packets, and dequeuing them for the upper half.

arm_dispatch_syscall in armv7-m clobbered r11 with 'mov r11, sp' and the
user-space callee-saved register value leaked back through the exception
frame when SYS_syscall_return restored the context, resulting in corrupted

In armv6-m, r4 was used to load g_stublookup (Thumb-1 cannot use ip for

causing the same class of register corruption.

This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,

to TSTATE_WAIT_SEM. In that window, the wait cannot yet
be aborted by sem_wait_irq(). If sem_wait then blocks
without re-checking unmasked pending signals, it can

Check for unmasked pending signals before touching the
semaphore count and return -EINTR if one is already pending.

This commit modularizes the curve25519 and idgen implementations in the
crypto subsystem.
Previously, curve25519.c and idgen.c were only compiled when
CONFIG_CRYPTO_RANDOM_POOL was enabled. However, cryptosoft.c (used by
software cipher support) has a direct dependency on curve25519 functions.
This caused linker errors (undefined reference to curve25519) when
software crypto was enabled but the random pool was disabled.
Changes:
- Introduce hidden Kconfig options CRYPTO_CURVE25519 and CRYPTO_IDGEN.
- Make CRYPTO_RANDOM_POOL select both CRYPTO_IDGEN and CRYPTO_CURVE25519.
- Make CRYPTO_CRYPTODEV_SOFTWARE_CRYPTO/KEYMGMT select CRYPTO_CURVE25519.
- Update CMakeLists.txt and Makefile to use the new config flags.
This ensures that required algorithms are automatically included in the
build regardless of whether the entropy pool is enabled.

The I2S BCLK frequency is calculated as:
bclk = sample_rate * total_slot * data_width
Previously, total_slot was always taken from the static config
(esp_i2s0_config / esp_i2s1_config), which is hardcoded to 2.
This is correct for mono and stereo, but wrong for TDM modes
with more than 2 channels (e.g. 4-channel recording with ES7210).
With 4 channels but total_slot=2, the BCLK is only half of what
it should be, causing the actual sample rate to be half of the
requested rate (e.g. requesting 16 kHz actually samples at 8 kHz).
Replace priv->config->total_slot with MAX(priv->channels, 2) in
all three BCLK calculation sites (i2s_check_mclkfrequency and
i2s_set_clock for both master and slave paths). The MIN of 2
preserves the I2S protocol requirement that at least 2 slots
exist even for mono, while correctly scaling for multi-channel
TDM configurations.

immediately after devif_conn_event(), leaving the subsequent
