- ESP32-C2: generic module board (UART0 20/19, 26MHz-crystal modules) - ESP32C2_DEVKITM_1: Espressif DevKitM-1, BOOT button on GPIO9, WS2812 RGB LED on GPIO8, both registered in board_com_api - saved board configs for the led/button examples
- esp32c2 has only 132KB heap; WiFi + BLE controller do not fit together, so ENABLE_BLUETOOTH now defaults off when CHIP_CHOICE is esp32c2 (still manually enableable); add the missing prompt, following the LINUX platform precedent - remove ENABLE_ESP_DISPLAY: unprompted, default n, zero references; the DISPLAY_NAME it wrapped is owned by src/peripherals/display/Kconfig
esp32c2 has no RMT peripheral, so the existing ws1280 driver cannot link there (esp_driver_rmt registers nothing). tdd_led_esp_ws1280_spi encodes each 1.25us WS2812 bit as 10 SPI bits @ 8MHz with a 64-byte zero tail for latch reset; requires DMA since polling mode is capped by the 64-byte FIFO. The RMT driver is excluded from esp32c2 builds.
