Ignore unsupported telnet subnegotiation payload until `IAC SE` so
option bytes do not leak into the first NSH command.
Keep existing NAWS handling intact and also treat `IAC IAC` inside
subnegotiation payload as an escaped `0xFF` data byte rather than a
subnegotiation terminator.
This makes subnegotiation parsing RFC-compliant for both unsupported
options and NAWS payload processing.

Fix adc_oversample() where priv->trovs (a bool, 0 or 1) was OR'd
directly into setbits instead of using ADC_CFGR2_TROVS (bit 9).
This caused triggered oversampling to never actually be enabled.
Fix ANIOC_WDOG_UPPER and ANIOC_WDOG_LOWER ioctls where the TR1
register was overwritten with only the new threshold value, zeroing
out the opposite threshold and the AWDFILT digital filter bits.
Use read-modify-write to preserve the other fields.

Replace GPIO driver with userled driver for Pin 12 and 13 LEDs.
The red LED on Pin 14 remains as system LED.
- Add user LED definitions in board.h (BOARD_LED1, BOARD_LED2)
- Add k210_userleds.c implementing board_userled_* functions
- Remove k210_gpio.c (GPIO driver no longer needed)
- Update CMakeLists.txt and Makefile for userled build
- Update k210_bringup.c to initialize userled instead of GPIO

Add detailed steps for copying nuttx.bin to eMMC via u-boot USB Mass
Storage (ums) mode, which exposes the eMMC as a USB drive on the host

Add a dedicated emmc board configuration that enables USDHC1 8-bit
eMMC access with MBR/GPT partition table parsing, instead of polluting
the base nsh defconfig. This allows users to build and test eMMC
functionality with:
cmake -DBOARD_CONFIG=imx95-a55-evk/emmc

Parse the partition table on /dev/mmcsd0 during board bringup and
register each partition as /dev/mmcsd0pN. MBR partitions have no
name field so a custom handler is needed instead of the default
register_partition which skips unnamed entries.

'mount -t vfat /dev/mmcsd0p0 /data'

imx9_dmapreflight() rejected unaligned buffers unconditionally, but
dmarecvsetup() has a bounce path via priv->rxbuffer for small
transfers. Add a buflen > sizeof(priv->rxbuffer) check so that
small reads (e.g. ext_csd 512-byte stack buffer) can use the
bounce buffer instead of failing with -EFAULT.

Port USDHC1 (eMMC) driver to the i.MX95 FRDM EVK board:
- Create imx95_pinmux.h with SD1/USDHC1 pin definitions
- Add USDHC1 pin macros to board.h
- Create board-level imx9_usdhc.c glue code
- Update imx9_bringup.c with DMA allocator and USDHC init
- Add SCMI clock guards in imx9_usdhc.c (imx95 clock roots
are owned by System Manager, direct CCM writes are no-ops)
- Fix CCM_CR_USDHC2 copy-paste bug to CCM_CR_USDHC1

Rename IMX9_IRQ_uSDHC{1,2,3} to IMX9_IRQ_USDHC{1,2,3} in both arm

by imx93_irq.h and the rest of the NuttX codebase. Remove the now
unnecessary USDHC IRQ alias block from arm64 imx95_irq.h.

The MMC CMD6 bus width switch was gated on priv->buswidth which is
derived from the SD SCR register. For MMC cards this field is never
set (unless SDIO_CAPS_4BIT_ONLY), so the CMD6 was skipped while the
host PROCTL DTW was still changed - causing a bus width mismatch and
data transfer timeouts.
Fix by checking priv->caps instead of priv->buswidth for MMC cards.
Also select EXT_CSD_BUS_WIDTH_8 when host reports SDIO_CAPS_8BIT.

Correct duplicate "is is" word found in 181 files throughout the
codebase.
In most cases "is is" was changed to "is", but in contexts like
"MCU is is sleep mode" it was corrected to "MCU in sleep mode".
Also fixes a "the the" typo in net/inet/inet_sockif.c.
This is a pure style/documentation fix that improves code readability.

Remove the CONFIG_K210_WITH_QEMU option and associated conditional
code paths. The reasons for removal are:
* Simplifies code path for real hardware by removing QEMU workarounds
* The current QEMU target uses sifive_u machine, which is not designed
for K210 emulation
* For RISC-V QEMU simulation, the qemu-rv (rv-virt) target is a better
choice
* Renode can be used as an alternative for K210 simulation if needed
