Implementation and Integration of Universal Flash Storage (UFS) device drivers

Registered by Venkatraman S

Universal Flash Storage is a new standard defined by JEDEC http://www.jedec.org/standards-documents/focus/flash/universal-flash-storage-ufs . Next generation of embedded devices will include flash memory parts in conformance to this standard which provides high performance storage with low power budget.

Whiteboard

The UFS standard utilizes the SCSI Architecture model and protocols. Compared to eMMC, the host controller definition is also standardized under the JESD220 and JESD223 specifications. Currently, the validation is blocked on the availability of the UFS device (expected at the end of 2012).

Linaro has yet to receive hardware; however, the code has been merged upstream with input from Linaro engineering.
