From 64afc7c32bf1634df9d9ff77efbc39225400744a Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Tue, 30 Jul 2019 08:37:40 +0800 Subject: [PATCH] memory-device: break the loop if tmp exceed the hinted range The memory-device list built by memory_device_build_list is ordered by its address, this means if the tmp range exceed the hinted range, all the following range will not overlap with it. And this won't change default pc-dimm mapping and address assignment stay the same as before this change.
