Most of the communication between host software and the UFS host controller or the UFS device respectively is via system memory tables, descriptors and buffers. These memory locations describe commands to be executed, the data transfer operations that are part of the commands, store status information coming back from the device and provide buffer space for data transactions.
For additional information on host data structures and programming procedures, refer to Universal Flash Storage Host Controller Interface (UFSHCI), JESD223C.
