22  *  Make sure the bootloader can load into main memory without overwriting itself.
24  *  ESP32-S3 ROM static data usage is as follows:
25  *  - 0x3fcd7e00 - 0x3fce9704: Shared buffers, used in UART/USB/SPI download mode only
26  *  - 0x3fce9710 - 0x3fceb710: PRO CPU stack, can be reclaimed as heap after RTOS startup
27  *  - 0x3fceb710 - 0x3fced710: APP CPU stack, can be reclaimed as heap after RTOS startup
28  *  - 0x3fced710 - 0x3fcf0000: ROM .bss and .data (not easily reclaimable)
30  *  The 2nd stage bootloader can take space up to the end of ROM shared
