This port adds support for the M5Stack Cardputer (M5Stamp S3 / ESP32-S3FN8, dual Xtensa LX7 @ 240 MHz, 8 MB flash, no PSRAM). It reuses the common ESP32-S3 board helpers and ships these configurations: - nsh: NuttShell over the USB-Serial-JTAG console - sdcard: microSD card on SPI3 (FAT) - fb: ST7789 240x135 display exposed as a framebuffer - wifi: Wi-Fi station - softap: Wi-Fi SoftAP with DHCP server - lvgl: LVGL graphics on the ST7789 (lvgldemo) Signed-off-by: Jorge Guzman <jorge.gzm@gmail.com>

Summary
Initial NuttX board port for the M5Stack Cardputer (M5Stamp S3 / ESP32-S3FN8, dual Xtensa LX7 @ 240 MHz, 8 MB flash, no PSRAM).
NSH console over USB-Serial-JTAG (/dev/ttyACM0)
1.14" ST7789 240x135 display (framebuffer and LVGL)
microSD card over SPI3 (FAT)
Native Wi-Fi: station and SoftAP (with DHCP server)
Ships six configurations: nsh, sdcard, fb, wifi, softap, lvgl.
Impact
With this port users can start developing on the M5Stack Cardputer using the documented pin map as a starting point, reusing the common ESP32-S3 board helpers. The remaining peripherals (NS4168 speaker, matrix keyboard, IR, RGB LED) are documented in the pin map and can be added in follow-up work.
Testing
All six configurations build clean:
ostestruns to completion on the board with all tests passing:
