From df48265036dc7332d488ded34aa298f7f5bf3513 Mon Sep 17 00:00:00 2001 From: Stephan Linz Date: Sat, 25 Feb 2012 00:48:31 +0000 Subject: net: ll_temac: Add LL TEMAC driver to u-boot Xilinx LocalLink Tri-Mode Ether MAC driver can be used by Xilinx Microblaze or Xilinx ppc405/440 in SDMA and FIFO mode. DCR or XPS bus can be used. The driver uses and requires MII and PHYLIB. CP: 4 warnings: 'Use of volatile is usually wrong' I won't fix this, because it depends on the network driver subsystem.
