6The Synopsys designware mobile storage host controller is used to interface
7a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
8differences between the core Synopsys dw mshc controller properties described
9by synopsys-dw-mshc.txt and the properties used by the Mellanox Bluefield SoC
10specific extensions to the Synopsys Designware Mobile Storage Host Controller.
