One of the watchdogs in the D1 SoC provides a "soft reset" function,
which allows software to immediately reset the entire SoC. Add a driver
so it can implement the SBI system reset function.

Unify all the file and function names of 'sifive_test' device, to use
the same prefix. This is also a preparatory patch for upcoming sifive
reset device.

lib: utils: reset: Add T-HEAD sample platform reset driver2021-04-22T09:43:53ZGuo Renguoren@linux.alibaba.com2021-04-17T16:26:17Zurn:sha1:49e422c5ad7abee9be0bb1066b1db65676e61985
This driver is for T-HEAD test chip, fpga. 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.

based on details in FDT passed by previous booting stage.
