From ef66a9d222718f080018d07f691faa1f01789e7d Mon Sep 17 00:00:00 2001 From: Stephen Neuendorffer Date: Wed, 6 Feb 2008 04:24:10 +1100 Subject: [POWERPC] Xilinx: hwicap: update booting-without-of.txt The ICAP device in Xilinx FPGAs differs slightly between different FPGAs. The driver needs an additional attribute in the device tree to distinguish this.
