Subject: [edk2-platforms][PATCH V2 09/11] Platform/Sgi: Add SMBIOS Type17 Table
Date: Sun, 16 May 2021 14:59:15 +0530 [thread overview]
Message-ID: <20210516092917.21124-10-pranav.madhu@arm.com> (raw)
In-Reply-To: <20210516092917.21124-1-pranav.madhu@arm.com>
Add the SMBIOS type 17 table (Memory Device) that includes the
specification of each installed memory device such as size of each
device, bank locator, memory device type, and other related information.
