This patch adds a driver to manage 15 and access global utilities block for LoongArch architecture Loongson-2 16 SoCs. Initially only reading SVR and registering soc device are 17 supported. Other guts accesses, such as reading firmware configuration 18 by default, should eventually be added into this driver as well. 19
