[net-next v1 0/6] Add synopsys designware GMAC NCSI support

[Minda Chen]

This patch set is for adding jhb100 GMAC NCSI function.
jhb100 is a Starfive new RISC-V SoC for datacenter BMC (BaseBoard
Managent Controller). Similar with Aspeed 27x0.

jhb100 contains 2 synopsys RMII(RGMII can be use as RMII) interfaces
GMAC, can be use as NCSI GMAC (network controller sideband interface),
do not connect with mdio PHY but connect with host server OCP network
device and share with network port.

The code which calling NCSI netdevice API is similar with
driver/net/ethernet/faraday/ftgmac100.c

The NCSI example:
