Re: Changing SiFive Unleashed core clock rate on 5.x kernel

[Carlos Eduardo de Paula <me@carlosedp.com>]

Hi Paul, I've built that 5.3 kernel and also used the DTs on my 5.2
Kernel but on both cases the network interface didn't come up.

I used both defconfig and my own .config, after this I've built latest
OpenSBI with the DT with command:

make CROSS_COMPILE=riscv64-unknown-linux-gnu- \
    PLATFORM=sifive/fu540 \
    FW_PAYLOAD_PATH=../linux/arch/riscv/boot/Image \
    FW_PAYLOAD_FDT_PATH=../linux/arch/riscv/boot/dts/sifive/hifive-unleashed-a00.dtb


Any adjustment I need?
