From 124b765051333010a3cf1038c601568001e39574 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 17 Jan 2023 13:16:26 +0100 Subject: OvmfPkg/PlatformInitLib: Add PlatformGetLowMemoryCB Add PlatformGetLowMemoryCB() callback function for use with PlatformScanE820(). It stores the low memory size in PlatformInfoHob->LowMemory. This replaces calls to PlatformScanOrAdd64BitE820Ram() with non-NULL LowMemory. Write any actions done (setting LowMemory) to the firmware log with INFO loglevel. Also change PlatformGetSystemMemorySizeBelow4gb() to likewise set PlatformInfoHob->LowMemory instead of returning the value. Update all Callers to the new convention.
