Reduces ESP32_GENERIC_C6 application flash size from 2024432 to 1813216 (206KB smaller). Also has benefit of reducing D/IRAM size, increasing free memory at runtime (167187 to 148584, -18603 bytes). Most of this savings comes from building with -Os instead of -O2, but about 10KB comes from using the SPI flash functions from the ROM. This work was funded through GitHub Sponsors.
