1* Altera SOCFPGA specific extensions to the Synopsys Designware Mobile
2  Storage Host Controller

4The Synopsys designware mobile storage host controller is used to interface
5a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
6differences between the core Synopsys dw mshc controller properties described
7by synopsys-dw-mshc.txt and the properties used by the Altera SOCFPGA specific
8extensions to the Synopsys Designware Mobile Storage Host Controller.
