Subject: [PATCH] memory: Fix wrong end address dump
Date: Wed, 22 Jun 2022 17:59:12 +0800 [thread overview]
Message-ID: <20220622095912.3430583-1-zhenzhong.duan@intel.com> (raw)
The end address of memory region section isn't correctly calculated
which leads to overflowed mtree dump:
Dispatch
Physical sections
......
