loongarch64: new target
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:
