Subject: [edk2-platforms][PATCH v1 1/1] Silicon/Qemu: Provide _STA ACPI method
Date: Tue, 28 Jun 2022 11:26:11 -0500 [thread overview]
Message-ID: <20220628162611.6252-1-Dimitrije.Pavlov@arm.com> (raw)
SBBR requires platforms to provide the _STA ACPI method for each
defined device. This patch implements a stub method that always
indicates devices are present and functional.
