* ArmPkg: Add FID definitions for Arm TRNGSami Mujawar2022-11-061-2/+107
| | | | | | | | | | | | | | | | | | Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668) The Arm True Random Number Generator Firmware, Interface 1.0, Platform Design Document (https://developer.arm.com/documentation/den0098/latest/) defines an interface between an Operating System (OS) executing at EL1 and Firmware (FW) exposing a conditioned entropy source that is provided by a TRNG back end. New function IDs have been defined by the specification for accessing the TRNG services. Therefore, add these definitions to the Arm standard SMC header.

* ArmPkg/ArmMonitorLib: Definition for ArmMonitorLib library classPierre Gondois2022-11-061-0/+42
| | | | | | | | | | | | | The ArmMonitorLib provides an abstract interface to issue an HyperVisor Call (HVC) or System Monitor Call (SMC) depending on the default conduit. The PcdMonitorConduitHvc PCD allows to select the default conduit. The new library relies on the ArmHvcLib and ArmSmcLib libraries. A Null instance of these libraries can be used for the unused conduit. Reviewed-by: Leif Lindholm <quic_llindhol@quicinc.com> Signed-off-by: Pierre Gondois <pierre.gondois@arm.com>
* ArmPkg/ArmMmuLib: Disable and re-enable MMU only when neededArd Biesheuvel2022-10-191-3/+4
| | | | | | | | | | | | | When updating a page table descriptor in a way that requires break before make, we temporarily disable the MMU to ensure that we don't unmap the memory region that the code itself is executing from. However, this is a condition we can check in a straight-forward manner, and if the regions are disjoint, we don't have to bother with the MMU controls, and we can just perform an ordinary break before make.
