Done.
I just send-out few patches to fix U-Boot SiFive Clock driver.
The U-Boot SiFive Clock driver fix series can be found in
riscv_unleashed_clk_sync_v1 branch of:
https://github.com/avpatel/u-boot.git
Users will also require OpenSBI DTB fix which can be found
in sifive_unleashed_dtb_fix_v1 branch of:
https://github.com/avpatel/opensbi.git
With above fixes, we can now use same DTB for both U-Boot
and Linux kernel (5.2-rc1). Although, users are free to pass a
different DTB to Linux kernel via TFTP.
I have tested SiFive serial and Cadance MACB ethernet on
both U-Boot and Linux (5.2-rc1)

Anup
