Subject: [edk2-devel] [PATCH v6 27/36] OvmfPkg/LoongArchVirt: Add serial port hook library
Date: Fri, 5 Jan 2024 17:45:54 +0800 [thread overview]
Message-ID: <20240105094554.2281689-1-lichao@loongson.cn> (raw)
In-Reply-To: <20240105094118.2279380-1-lichao@loongson.cn>
Add a serial port hook library in LoongArchVirt named
Fdt16550SerialProtHookLib, this library is referenced from ArmVirtPkg.
LoongArch QEMU virtual machine uses register of LOONGARCH_CSR_KS1 to
transfer serial port base addres from the PEI phase to the DXE phase.
