Status of the community kernel (sunxi-3.4) / U-Boot

 * Patch that adds support for GMAC to the community kernel is submitted to the mailing list, review is pending. Be first to review!
 * GMAC support is not added to U-Boot yet. It means you will have no network connection under U-Boot and need to fiddle with uSD cards.
 * Sources for U-Boot driver (although sun6i) are available. They neither have been tested nor merged yet, see http://git.rhombus-tech.net/?p=u-boot.git;a=blob;f=drivers/net/sun6i_gmac.c;h=f52b11d84d85f6bb06f485d470dc72090273b185;hb=refs/heads/allwinner-sunxi-a31
