And allows ARCH_CANAAN to be selected for other Canaan SoCs. Then, since we have Canaan Kendryte K230 with MMU now, the use of SOC_CANAAN is no longer only referred to K210. Thus, we introduce a new symbol SOC_CANAAN_K210 for any conditional code or driver selection specific to the K210, so users will not try to build some K210-specific things when MMU is enabled and see it fails to boot on K210.
