spi_flash: add external flash support on esp32c3 Closes IDF-2650, IDF-2651, and IDF-2399 See merge request espressif/esp-idf!12121
Bootloader Support Component ============================ Overview -------- "Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app. Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
