Add target for Loongson LoongArch64-based boards. LoongArch is a new RISC ISA developed by Loongson. It's a bit like MIPS or RISC-V. LoongArch includes both 32-bit and 64-bit versions (LoongArch32/LoongArch64). Loongson 3A5000 and 3A6000 are the two existing CPUs of LoongArch64 and is used for PC products. It's BIOS supports ACPI and UEFI-only boot. These CPUs supports SMP and SMT. At present only LoongArch64 is supported by linux kernel. Toolchain requirement: binutils >= 2.40 gcc >= 13.1 For details, please check the following links: https://lwn.net/Articles/861951/ https://loongson.github.io/LoongArch-Documentation/README-EN.html Signed-off-by: Weijie Gao <hackpascal@gmail.com>
