The uploaded code generates firmware to support Linux launching on the LoongArch platform under qemu, So it will run in a virtual machine. LoongArch is the general processor architecture of Loongson. You can get the latest LoongArch documents or LoongArch tools at https://github.com/loongson/. You can also view the code through the Loongson community. The edk2 code in Loongson community: https://github.com/loongson/edk2/tree/LoongArch The edk2-platform code in Loonson community: https://github.com/loongson/edk2-platforms The qemu code in Loongson community: https://gitlab.com/qemu-project/qemu.git The LoongArch Documentation in Loongson community: https://github.com/loongson/LoongArch-Documentation/tree/main/docs The all patches at: https://github.com/loongson/edk2-platforms/tree/devel-LoongArch-patch v2 changes: - Remove the inline assembly from StableTimerLib. - troubleshoot TAB strings, convert TAB characters to spaces. - remove smm related code, loongarch has no smm mode. v3 changes: - delete ExtractHandler related code. - Boot UEFI with low 256M memory. - Modify common interrupt handling. v4 changes: - Remove qemu flash related code. - Modify fdt base address. v5 changes: - Add Udf driver support. - Split readme file into a separate patch. - Modify the code style - delete extra blank lines - use the assembly function definition macros in MdePkg - sort out the PCD variable Token value.
