Subject: [patch 10/13] Delete SGI UV1 detection.
Date: Wed, 01 Jul 2020 09:17:41 -0500 [thread overview]
Message-ID: <20200701141732.706351085@hpe.com> (raw)
In-Reply-To: 20200701141731.377252388@hpe.com
As a part of UV1 platform removal, don't try to recognize the platform
through DMI to set the EFI_UV1_MEMMAP bit.
