ArmVirtPkg: create QemuVirtMemInfoLib version for ArmVirtQemu The QemuVirtMemInfoLib ArmVirtMemInfoLib implementation created for ArmVirtQemuKernel does exactly what we need for ArmVirtQemu, the only difference being that the latter is PrePeiCore based, and so it uses a different method to ensure that PcdSystemMemorySize is set when ArmVirtGetMemoryMap() is called. On ArmVirtQemu, we currently abuse the implied ordering guarantees provided by ArmPlatformLib, by implementing this as follows: ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.inf [ArmVirtPkg/ArmVirtQemu.dsc] InitializeMemory() [ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.c] ArmPlatformInitializeSystemMemory() [ArmVirtPkg/Library/ArmVirtPlatformLib/Virt.c] // // set PcdSystemMemorySize from the DT // MemoryPeim() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] InitMmu() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] ArmPlatformGetVirtualMemoryMap() [ArmVirtPkg/Library/ArmVirtPlatformLib/VirtMem.c] // // consume PcdSystemMemorySize // Given that we are trying to get rid of ArmPlatformLib, or at least remove some of these API functions that are never used for their original purpose by any platforms, we need to move the PCD assignment elsewhere. So create a PEIM-only version of QemuVirtMemInfoLib especially for ArmVirtQemu, and add the PCD assignment code to its constructor.
