14 /** Simplified memory map for the bootloader.
15  *  Make sure the bootloader can load into main memory without overwriting itself.
17  *  ESP32-S2 ROM static data usage is as follows:
18  *  - 0x3ffeab00 - 0x3fffc410: Shared buffers, used in UART/USB/SPI download mode only
19  *  - 0x3fffc410 - 0x3fffe710: CPU stack, can be reclaimed as heap after RTOS startup
20  *  - 0x3fffe710 - 0x40000000: ROM .bss and .data (not easily reclaimable)
22  *  The 2nd stage bootloader can take space up to the end of ROM shared
