Subject: Xilinx: ARM: net: Move the Zynq GEM driver to drivers/net
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=27033864520d9492ba3f9a5829d5ce5876be3890;p=thirdparty%2Fu-boot.git

Xilinx: ARM: net: Move the Zynq GEM driver to drivers/net

The Gigabit Ethernet Mac driver for Zynq should be available to any
board that uses Zynq
