Subject: [PATCH edk2 v2 1/5] Silicon/Hisilicon: Change updating dsdt in ready to boot event
Date: Wed, 27 May 2020 22:33:54 +0800	[thread overview]
Message-ID: <1590590038-19724-2-git-send-email-huangming23@huawei.com> (raw)
In-Reply-To: <1590590038-19724-1-git-send-email-huangming23@huawei.com>

The dsdt need be updated before boot to OS, so change the updating
to ready to boot event and can remove the needless dependence.
