FYI for the Rock64 V2 that I tested with . . .

Booting attempts report:

Using DTB provided by EFI at 0x80f0000.

So stopping in u-boot instead . . .

=> fdt addr 0x80f0000
=> fdt print /
. . .
        ethernet at ff540000 {
                . . .
                phy-mode = "rgmii";
                . . .
                snps,reset-delays-us = <0x00000000 0x00002710 0x0000c350>;
                tx_delay = <0x00000024>;
                rx_delay = <0x00000018>;
                . . .
        };
. . .

(Using fdt print in u-boot also picks up any
dynamic changes that u-boot might have made.)
