+ * IROM/DRAM definition in QEMU:
+ *     [ESP32S3_MEMREGION_IROM] = { 0x40000000, 0x60000 },
+ *     [ESP32S3_MEMREGION_DRAM] = { 0x3FC80000, 0x70000 },
+ *
+ * In theory we could use whole DRAM section, but I had some faults when using
+ * memory in range 0x3ffae000 - 0x3ffb0000
+ *
+ * But used memory range for data such as esp-idf for ESP32S3 to satisfy user's
+ * expectation on chip emulation
+ *
+ * Pass '--defsym=entire_dram_seg=1' to linker script to use whole DRAM
