Hi Anup,

Tested the entire V9 series with OpenSBI and mainline u-boot based
on commit fc6c0e29a28f6 ("Prepare v2019.07-rc4") along with few
Ramon Fried's  patches present in your riscv_unleashed_clk_sync_v9 branch:
between commit fc6c0e29a28f6 ("Prepare v2019.07-rc4") and
commit 1a417ef71ce1 ("net: macb: apply sane DMA configuration").

With tftp able to boot complete linux.

MDIO and mii utils in U-boot correctly display details of Microsemi PHY
VSC8541-01 device as below:

=> mdio list
ethernet@10090000:
0 - Microsemi VSC8541 <--> ethernet@10090000

=> mii info 0
PHY 0x00: OUI = 0x01C1, Model = 0x37, Rev = 0x01, 100baseT, FDX

PHY address read from OTP:
Address in ROM is      70:b3:d5:92:f0:1f
