York Sun 316f0d0f8f powerpc: mpc85xx: Fix static TLB table for SDRAM 
Most predefined TLB tables don't have memory coherence bit set for
SDRAM. This wasn't an issue before invalidate_dcache_range() function
was enabled. Without the coherence bit, dcache invalidation doesn't
automatically flush the cache. The coherence bit is already set when
dynamic TLB table is used. For some boards with different SPL boot
method, or with legacy fixed setting, this bit needs to be set in
TLB files.

README 

The uCP1020 product family (ucp1020) is an Arcturus Networks Inc. System on Modules
product featuring a Freescale P1020 CPU, optionally populated with 1, 2 or 3 Gig-Ethernet PHYs,
DDR3, NOR Flash, eMMC NAND Flash and/or SPI Flash.

Information on the generic product family can be found here:
	http://www.arcturusnetworks.com/products/ucp1020

The UCP1020 several configurable options
========================================

- the selection of populated phy(s):
	KSZ9031 (current default for eTSEC 1 and 3)

- the selection of boot location:
	SPI Flash or NOR flash

The UCP1020 includes 2 default configurations
=============================================
NOR boot image:
	configs/UCP1020_defconfig
SPI boot image:
	configs/UCP1020_SPIFLASH_defconfig

The UCP1020 adds an additional command in cmd_arc.c to access and program
SPI resident factory defaults for serial number, and 1, 2 or 3 Ethernet
HW Addresses.


Build example
=============

make distclean
make UCP1020_defconfig
make

Default Scripts
===============
A default upgrade scripts is included in the default environment variable example:

B$ run tftpflash

Dual Environment
================

This build enables dual / failover environment environment.

NOR Flash Partition declarations and scripts
============================================
Several scripts are available to allow TFTP of images and programming directly
into defined NOR flash partitions. Examples:

B$ run program0
B$ run program1
B$ run program2
