[edk2-devel] [PATCH v4 08/13] UefiCpuPkg: Added a new PCD named PcdLoongArchExceptionVectorBaseAddress

["Chao Li" <lichao@loongson.cn>]

Added PcdLoongArchExceptionVectorBaseAddress use for storing the CPU
exception vector base address. This PCD can be populated at build time
or changed at runtime, and is used only by LoongArch.
