From d5254f149da9e6cd649d887b042ce577ef3ba78d Mon Sep 17 00:00:00 2001 From: Alessandro Rubini Date: Sat, 24 Jan 2009 18:10:37 +0100 Subject: Initial support for Nomadik 8815 development board The NMDK8815 board is distributed by ST Microelectornics. Other (proprietary) code must be run to unlock the CPU before U-Boot runs. doc/README.nmdk8815 outlines the boot sequence. This is the initial port, with basic infrastructure and a working serial port.
