Thanks for your patch, which became commit 57985788158a5a6b ("riscv:
dts: add initial support for the SiFive FU740-C000 SoC").

I'm wondering why you're using
compatible = "sifive,bullet0", "riscv";
According to your own commit 75e6d7248efccc2b ("dt-bindings: riscv:
Update DT binding docs to support SiFive FU740 SoC"), it should be
compatible = "sifive,u74-mc", "riscv";
instead.
Likewise, the older arch/riscv/boot/dts/sifive/fu540-c000.dtsi is using
compatible = "sifive,e51", "sifive,rocket0", "riscv";
and
compatible = "sifive,u54-mc", "sifive,rocket0", "riscv";
but according to the DT bindings the rocket part should not be present.
Is there any specific reason for that?
Should the DT bindings and/or the DTS files be fixed?
Thanks!
Gr{oetje,eeting}s,
