2021-02-27ArmPkg: Fix uninitialised variable in ArmMmuStandaloneMmLibSami Mujawar1-144/+179
The following patches added support for StandaloneMM using FF-A: 9da5ee116a28 ArmPkg: Allow FF-A calls to set memory region's attributes 0e43e02b9bd8 ArmPkg: Allow FF-A calls to get memory region's attributes However, in the error handling logic for the Get/Set Memory attributes, the CLANG compiler reports that a status variable could be used without initialisation. This issue is a false positive and is not seen with GCC. The Get/Set Memory attributes operation is atomic and therefore an FFA_INTERRUPT or FFA_SUCCESS response is not expected in response to FFA_MSG_SEND_DIRECT_REQ. So the remaining cases that could occur are: - the target sends FFA_MSG_SEND_DIRECT_RESP with a success or failure code. or - FFA_MSG_SEND_DIRECT_REQ transmission failure. Therefore, - reorder the error handling conditions such that it prevents the uninitialised variable issue being flagged by CLANG. - move the repetitive code to a static helper function and add documentation at the appropriate places. - fix error handling in functions that invoke GetMemoryPermissions().

2018-11-27ArmPkg/ArmMmuLib: Add MMU Library suitable for use in S-EL0.Achin Gupta2-0/+221
The Standalone MM environment runs in S-EL0 in AArch64 on ARM Standard Platforms. Privileged firmware e.g. ARM Trusted Firmware sets up its architectural context including the initial translation tables for the S-EL1/EL0 translation regime. The MM environment will still request ARM TF to change the memory attributes of memory regions during initialization. The Standalone MM image is a FV that encapsulates the MM foundation and drivers. These are PE-COFF images with data and text segments. To initialise the MM environment, Arm Trusted Firmware has to create translation tables with sane default attributes for the memory occupied by the FV. This library sends SVCs to ARM Trusted Firmware to request memory permissions change for data and text segments. This patch adds a simple MMU library suitable for execution in S-EL0 and requesting memory permissions change operations from Arm Trusted Firmware.
