From 5bf7b1ac69e796ff508325eab2b8c27cc782372d Mon Sep 17 00:00:00 2001 From: Wim Vervoorn Date: Tue, 4 Feb 2020 13:21:41 +0100 Subject: mb/facebook/monolith: Use serial number and UUID from VPD The serial number and UUID returned by DMI are retrieved from VPD. The solution supports a 16 character "serial_number" and a 36 character "UUID" string.
