Port of the DAKEFPV H743 flight controller (non-Pro, STM32H743 variant) to PX4 v1.16. Hardware verified against Betaflight and ArduPilot hwdefs. Sensors (verified hardware): - 2x ICM-42688P IMUs on SPI1 (ROLL_180) and SPI4 (PITCH_180) - SPL06 barometer on I2C2 @ 0x76 (requires battery power) - Micron N25Q128 16MB SPI NOR flash on SPI3 (PA15 CS), mounted as /fs/microsd using littlefs for blackbox logging Key implementation details: - BOARD_FLASH_SIZE = 16x128K (full 2MB), BOARD_FLASH_SECTORS = 14, APP_RESERVATION_SIZE = 128K for param sector at 0x081E0000 - Onboard flash is Micron N25Q128 (JEDEC 0x20/0xBA/0x18), not Winbond; w25 driver extended via NuttX submodule patch - I2C2 registered as external bus; baro and compass share bus cleanly when compass is started after baro via extras.txt - VBUS sensing disabled: PA9 is shared with USART1 TX (GPS1) - USB identity 0x1209:0x5741 matches ArduPilot User extras.txt workflow: rc.board_extras creates /fs/microsd/etc/ and seeds extras.txt on first boot. Users add driver commands via NSH append.

cc @engineer-dakefpv — PX4 port for the DAKEFPV H743. All CI passing. Would appreciate a review of the pin assignments and hardware configuration. |

Superseded by #27522, which consolidates the H743, H743 Pro and H743 Slim board support into a single PR. Closing in favor of that one. |

extras.txtfile is seeded on first boot for optional driver start commands (IST8310 compass at 0x0C, etc.). MAVLink FTP write does not work on NuttX littlefs; extras must be written via NSH>>append.Tested on hardware: dual IMUs, SPL06 baro, GPS, DShot, MAVLink telemetry all verified.
