Subject: [PATCH v8 12/21] ArmPkg: Add Universal/Smbios/OemMiscLibNull
Date: Sun, 7 Feb 2021 17:52:45 -0700 [thread overview]
Message-ID: <20210208005254.12176-13-rebecca@nuviainc.com> (raw)
In-Reply-To: <20210208005254.12176-1-rebecca@nuviainc.com>
Add a Null implementation of OemMiscLib.
OemMiscLib provides functions that platforms implement to fill in
SMBIOS information for the SmbiosMiscDxe and ProcessSubClassDxe drivers.
