If Enabled, if SPI_CONFIG_SIZE is bigger then 10MB+576KB,
then you can have 4MB more space to map the SPIRAM.
However, the AHB bus is slower than other data cache buses.

help
Select the speed for the SPI RAM chip.
If SPI RAM is enabled, we only support three combinations of SPI speed mode we supported now:
1. Flash SPI running at 40Mhz and RAM SPI running at 40Mhz
2. Flash SPI running at 80Mhz and RAM SPI running at 40Mhz
3. Flash SPI running at 80Mhz and RAM SPI running at 80Mhz
Note: If the third mode(80Mhz+80Mhz) is enabled for SPI RAM of type 32MBit, one of the HSPI/VSPI host
will be occupied by the system. Which SPI host to use can be selected by the config item
SPIRAM_OCCUPY_SPI_HOST. Application code should never touch HSPI/VSPI hardware in this case. The
option to select 80MHz will only be visible if the flash SPI speed is also 80MHz.
(ESPTOOLPY_FLASHFREQ_80M is true)
