From 110dfcd9285fa01a73b2e59bc01f9e9ebd53adbe Mon Sep 17 00:00:00 2001 From: Hao Wu Date: Mon, 11 Jun 2018 09:47:50 +0800 Subject: [PATCH] MdeModulePkg: Add definitions for Storage Security Command PPI REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409 This commit will add the definitions for Storage Security Command (SSC) PPI. This PPI will be be used to abstract mass storage devices to allow code running in the PEI phase to send security protocol commands to mass storage devices without specific knowledge of the type of device or controller that manages the device. More specifically, the PPI will provide services to: * Get the number of mass storage devices managed by a instance of the SSC PPI (by service 'GetNumberofDevices'); * Get the identification information (DevicePath) of a managing mass storage devices (by service 'GetDevicePath'); * Send security protocol commands to mass storage devices (by services 'ReceiveData' and 'SendData').
