Subject: [PATCH v2] PCI/ACPI: Suppress missing MCFG message
Date: Tue,  8 Sep 2020 16:03:59 -0500	[thread overview]
Message-ID: <20200908210359.569294-1-jeremy.linton@arm.com> (raw)

MCFG is an optional ACPI table. Given there are machines
without PCI(e) (or it is hidden) we have been receiving
queries/complaints about what this message means given
its being presented as an error.

Lets reduce the severity, the ACPI table list printed at
boot will continue to provide another way to detect when
the table is missing.
