/* Linker script for the ESP32-C3
 *
 * The ESP32-C3 has a rather funky memory layout, more like its Xtensa
 * predecessors than like other RISC-V chips:
 *   - It has 384kB of regular RAM. This RAM can be used both as data RAM and
 *     instruction RAM, but needs to be accessed via a different address space
 *     (DRAM/IRAM).
 *   - It has another 16kB of RAM, that could be used as regular RAM but is
 *     normally used by the flash cache.
 *   - It has 8MB of address space for the DROM and IROM, but for some reason
 *     this address space is shared. So it isn't possible to map all DROM at
 *     0x3C000000 and all DRAM at 0x42000000: they would overlap.
 *   - The MMU works in pages of 64kB, which means the bottom 16 bits of the
 *     address in flash and the address in DROM/IROM need to match.
 *   - Memory in DRAM and IRAM is loaded at reset by the ROM bootloader.
 *     Luckily, this doesn't have significant alignment requirements.
 *
 * This linker script has been written to carefully work around (or with) these
 * limitations:
 *   - It adds dummy sections so that the bottom 16 bits of the virtual address
 *     and the physical address (in the generated firmware image) match.
 *   - It also offsets sections that share an address space using those same
 *     dummy sections.
 *   - It sorts the sections by load address, to avoid surprises as esptool.py
 *     also does it.
 * This way, it's possible to create a very small firmware image that still
 * conforms to the expectations of esptool.py and the ROM bootloader.
