Laszlo Ersek c5d917158d OvmfPkg/EmuVariableFvbRuntimeDxe: stop using PcdVariableStoreSize ... In commit 62f43f7c19, we set PcdVariableStoreSize to the same value as PcdFlashNvStorageVariableSize (which in turn comes from VARS_LIVE_SIZE in "OvmfPkg.fdf.inc"). This equality between both PCDs is a false requirement from EmuVariableFvbRuntimeDxe. FVB drivers should use PcdFlashNvStorageVariableSize for supporting non-volatile variables (even if they happen to be kept in RAM only), along the other PcdFlashNvStorage* PCDs. Whereas PcdVariableStoreSize is for variables that are volatile at the gRT->SetVariable() / gRT->GetVariable() API level. (PlatformPei too bases the preallocation for EmuVariableFvbRuntimeDxe on PcdFlashNvStorageFtwSpareSize.) Replace PcdVariableStoreSize in EmuVariableFvbRuntimeDxe with the same-value PcdFlashNvStorageVariableSize. This means no change in behavior, and it allows us to increase PcdVariableStoreSize in a later patch without disturbing EmuVariableFvbRuntimeDxe (or PlatformPei).
