Subject: [edk2-devel] [PATCH v4 08/37] MdePkg: Add IOCSR operation for LoongArch
Date: Tue, 12 Dec 2023 21:11:50 +0800 [thread overview]
Message-ID: <20231212131150.2470548-1-lichao@loongson.cn> (raw)
In-Reply-To: <20231212130932.2467028-1-lichao@loongson.cn>
Add IoCsrRead8, IoCsrRead16, IoCsrRead32, IoCsrRead64, IoCsrWrite8,
