It's impossible to test this file. You miss Makefile.
Kelly: I've add aspeed-bmc-asus-x4tf.dtb in Makefle.

earlycon is a debugging feature, not mainline. Also, move console to stdout-path, so entire bootargs can be dropped.
Kelly: I've moved "bootargs" into "stdout-path" and resend my patch.

No underscores in node names. This applies everywhere.

Why? It makes it entirely pointless.

Wrong placement. Also tools would tell you that.
It does not look like you tested the DTS against bindings. Please run `make dtbs_check W=1` (see Documentation/devicetree/bindings/writing-schema.rst or https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
Kelly: I've checked our dts, removed unnecessary parts and run the DTS check script.

That's a syscon property?

I am going to skip the rest. Please fix all the trivialities and test your patches with tools.

I've checked our dts, removed unnecessary parts and run the DTS check script.
