+ * Marlin currently requires 3 SPI classes:
+ *
+ * SPIClass:
+ * This class is normally provided by frameworks and has a semi-default interface.
+ * This is needed because some libraries reference it globally.
+ *
+ * SPISettings:
+ * Container for SPI configs for SPIClass. As above, libraries may reference it globally.
+ *
+ * These two classes are often provided by frameworks so we cannot extend them to add
+ * useful methods for Marlin.
+ *
+ * MarlinSPI:
+ * Provides the default SPIClass interface plus some Marlin goodies such as a simplified
+ * interface for SPI DMA transfer.
