From 2b224609568988a7d8db22d372b232a69155733f Mon Sep 17 00:00:00 2001 From: Reinhard Arlt Date: Thu, 10 Nov 2011 08:51:57 +0000 Subject: CPCI750: Add CPCI-HD/2 support This patch adds support for the esd CPCI-HD/2 board to u-boot for CPCI-CPU/750. As the primary devices on the CPCI-HD/2 board are connected to device 1 and 3, the device must be swapped.
