Daniel Golle bc25519f98 uboot-mediatek: add builds for BananaPi BPi-R3 mini 
The R3 mini comes with two Airoha EN8811H PHYs for 2.5G Ethernet.
The driver added to U-Boot expects the firmware for the PHY to be
stored inside UBI volume en8811h-fw or MMC boot1 hardware partition.

Subject: [PATCH] net: phy: add support for Airoha ethernet PHY driver
This patch adds support for Airoha ethernet PHY driver.
If GMAC2 of your board connects to Airoha EN8801S, please change the eth
node as follow:
&eth {
status = "okay";
mediatek,gmac-id = <1>;
mediatek,sgmiisys = <&sgmiisys1>;
phy-mode = "sgmii";
phy-handle = <&phy5>;
phy5: eth-phy@5 {
reg = <24>;
};
};
If GMAC2 of your board connects to Airoha EN8811H, please change the eth
node as follow:
&eth {
status = "okay";
mediatek,gmac-id = <1>;
mediatek,sgmiisys = <&sgmiisys1>;
phy-mode = "2500base-x";
phy-handle = <&phy5>;
fixed-link {
speed = <2500>;
full-duplex;
};
phy5: eth-phy@5 {
reg = <15>;
};
};
