From 887e2ec9ecf49366a60a49b32b73825804909865 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 7 Sep 2006 11:51:23 +0200 Subject: Add support for AMCC Sequoia PPC440EPx eval board - Add support for PPC440EPx & PPC440GRx - Add support for PPC440EP(x)/GR(x) NAND controller in cpu/ppc4xx directory - Add NAND boot functionality for Sequoia board, please see doc/README.nand-boot-ppc440 for details - This Sequoia NAND image doesn't support environment in NAND for now. This will be added in a short while.
