Subject: ppc4xx: Support for Yucca board with 440SPe Rev A added to
 44x_spd_ddr2.c

The new boardspecific DDR2 controller configuration is used for the Yucca
board. Now the Yucca board with 440SPe Rev. A chips is also supported.

From d2f68006627eda6cb6c7f364bddf621dbfd2fc68 Mon Sep 17 00:00:00 2001
From: Eugene OBrien <eugene.obrien@advantechamt.com>
Date: Tue, 31 Jul 2007 10:24:56 +0200
Subject: ppc4xx: Update AMCC Bamboo 440EP support

Changed storage type of cfg_simulate_spd_eeprom to const
Changed storage type of gpio_tab to stack storage
(Cannot access global data declarations in .bss until afer code relocation)

Improved SDRAM tests to catch problems where data is not uniquely addressable
(e.g. incorrectly programmed SDRAM row or columns)

Added CONFIG_PROG_SDRAM_TLB to support Bamboo SIMM/DIMM modules
Fixed AM29LV320DT (OpCode Flash) sector map
