External memory is accessed via SPI0. When modifying the SPI0 registers, should put the code in internal RAM. Otherwise when there is an ongoing SPI0 transaction, CPU changes the SPI0 registers. This is dangerous. Besides, modifying SPI0 registers may lead external memory to an unstable state. Therefore putting these code in internal RAM is necessary. |

esp_hw_support
This component contains hardware-related operations for supporting the system. These operations
are one level above that of hal in that these(1) use system services such as memory allocation, logging, scheduling
or (2) may be multi-step operations involving/affecting multiple parts of the SoC.
Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
