It could work with all T-HEAD riscv processors: C9xx series. example1: (Using io-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; entry-reg = <0xff 0xff019050>; entry-cnt = <4>; control-reg = <0xff 0xff015004>; control-val = <0x1c>; csr-copy = <0x7f3 0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc>; }; example2: (Using csr-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; using-csr-reset; csr-copy = <0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc 0x3b0 0x3b1 0x3b2 0x3b3 0x3b4 0x3b5 0x3b6 0x3b7 0x3a0>; }; example3: (Only delegate plic enable to S-mode) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; }; After this patch, all T-HEAD c9xx would use platform/generic with fw_dynamic as default: CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic FW_PIC=y /usr/bin/make The platform/thead will be deprecated.
