Subject: [PATCH v3 1/4] hvmloader/ovmf: remove hardcoded OVMF loading location
Date: Thu, 21 Nov 2013 16:22:38 +0000 [thread overview]
Message-ID: <1385050961-32637-2-git-send-email-wei.liu2@citrix.com> (raw)
In-Reply-To: <1385050961-32637-1-git-send-email-wei.liu2@citrix.com>
Load OVMF from (100000000ULL - sizeof(ovmf)) to 0xFFFFFFFF, with proper
rounding down.
Tested with OVMF release build (1 MB) and debug build (2 MB), both
worked fine.
