Subject: [PATCH edk2-platforms v3 3/4] Silicon/Hisilicon/Acpi: Add update sas address feature
Date: Tue, 9 Jun 2020 21:27:24 +0800 [thread overview]
Message-ID: <1591709245-44527-4-git-send-email-huangming23@huawei.com> (raw)
In-Reply-To: <1591709245-44527-1-git-send-email-huangming23@huawei.com>
The updating sas address feature is similar with apdating mac address.
Modify updating dsdt flow for add this feature.
