* sunxi: Fix gmac not working reliable on the BananapiHans de Goede2014-10-08-0/+9
| | | | | | | | | | | | | | | | | | | | | In order for the gmac nic to work reliable on the Bananapi, we need to set bits 10-12 GTXDC "GMAC Transmit Clock Delay Chain" of the GMAC clk register (0x01c20164) to 3. Without this about 9 out of 10 ethernet packets get lost, with this setting there is no packet loss. So far setting these bits is only necessary on the Bananapi, so this commit solves this with a bit of #ifdef CONFIG_BANANAPI code. If in the future we need to do something similar for other boards, we can create a specific CONFIG_FOO option for this then.

* sunxi: Add support for using MII phy-s with the GMAC nicChen-Yu Tsai2014-07-06-0/+11
| | | | | | | | | | Many A20 boards (ie Cubieboard2, A20-OLinuXino_MICRO) use an 100 Mbit MII phy together with the GMAC nic found in the A20 SoC, add support for this (this will get used when we add these boards in a later patch).
