Subject: [edk2-devel] [PATCH v7 13/37] UefiCpuPkg: Add CpuMmuLib.h to UefiCpuPkg
Date: Fri, 12 Jan 2024 16:24:08 +0800 [thread overview]
Message-ID: <20240112082408.3288494-1-lichao@loongson.cn> (raw)
In-Reply-To: <20240112082153.3284189-1-lichao@loongson.cn>
Add a new header file CpuMmuLib.h, whitch is referenced from
ArmPkg/Include/Library/ArmMmuLib.h. Currently, only support for
LoongArch64 is added, and more architectures can be accommodated in the
future.
