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.

Overview
=========
C29XPCIE board is a series of Freescale PCIe add-in cards to perform
as public key crypto accelerator or secure key management module.
It includes C293PCIE board, C293PCIE board and C291PCIE board.
The Freescale C29x family is a high performance crypto co-processor.
It combines a single e500v2 core with necessary SEC engines.
(maximum core frequency 1000/1200 MHz).

The C29xPCIE board features are as follows:
Memory subsystem:
	- 512Mbyte unbuffered DDR3 SDRAM discrete devices (32-bit bus)
	- 64 Mbyte NOR flash single-chip memory
	- 4 Gbyte NAND flash memory
	- 1 Mbit AT24C1024 I2C EEPROM
	- 16 Mbyte SPI memory

Interfaces:
	- 10/100/1000 BaseT Ethernet ports:
		- eTSEC1, RGMII: one 10/100/1000 port
		- eTSEC2, RGMII: one 10/100/1000 port
	- DUART interface:
		- DUART interface: supports two UARTs up to 115200 bps for
		   console display

Board connectors:
	- Mini-ITX power supply connector
	- JTAG/COP for debugging

Physical Memory Map on C29xPCIE
===============================
Address Start   Address End   Memory type
0x0_0000_0000 - 0x0_1fff_ffff   512MB DDR
0xc_0000_0000 - 0xc_8fff_ffff   256MB PCIE memory
0xf_ec00_0000 - 0xf_efff_ffff   64MB NOR flash
0xf_ffb0_0000 - 0xf_ffb7_ffff   512KB SRAM
0xf_ffc0_0000 - 0xf_ffc0_ffff   64KB PCIE IO
0xf_ffdf_0000 - 0xf_ffdf_0fff   4KB CPLD
0xf_ffe0_0000 - 0xf_ffef_ffff   1MB CCSR

Serial Port Configuration on C29xPCIE
=====================================
Configure the serial port of the attached computer with the following values:
	-Data rate: 115200 bps
	-Number of data bits: 8
	-Parity: None
	-Number of Stop bits: 1
	-Flow Control: Hardware/None

Settings of DIP-switch
======================
  SW5[1:4]= 1111 and SW5[6]=0 for boot from 16bit NOR flash
  SW5[1:4]= 0110 and SW5[6]=0 for boot from SPI flash
Note: 1 stands for 'off', 0 stands for 'on'

Build and program U-Boot to NOR flash
==================================
1. Build u-boot.bin image example:
	export ARCH=powerpc
	export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
	make C293PCIE

2. Program u-boot.bin into NOR flash
	=> tftp $loadaddr $uboot
	=> protect off eff40000 +$filesize
	=> erase eff40000 +$filesize
	=> cp.b $loadaddr eff40000 $filesize

3. Check SW5[1:4]= 1111 and SW5[6]=0, then power on.

Alternate NOR bank
==================
There are four banks in C29XPCIE board, example to change bank booting:
1. Program u-boot.bin into alternate NOR bank
	=> tftp $loadaddr $uboot
	=> protect off e9f40000 +$filesize
	=> erase e9f40000 +$filesize
	=> cp.b $loadaddr e9f40000 $filesize

2. Switch to alternate NOR bank
	=> cpld_cmd reset altbank [bank]
	- [bank] bank value select 1-4
	- bank 1 on the flash 0x0000000~0x0ffffff
	- bank 2 on the flash 0x1000000~0x1ffffff
	- bank 3 on the flash 0x2000000~0x2ffffff
	- bank 4 on the flash 0x3000000~0x3ffffff
	or set SW5[7]= ON/OFF and SW5[7]= ON/OFF, then power on again.

Build and program U-Boot to SPI flash
==================================
1. Build u-boot-spi.bin image
	make C29xPCIE_SPIFLASH_config; make
	Need the boot_format tool to generate u-boot-spi.bin from the u-boot.bin.

2. Program u-boot-spi.bin into SPI flash
	=> tftp $loadaddr $uboot-spi
	=> sf erase 0 100000
	=> sf write $loadaddr 0 $filesize

3. Check SW5[1:4]= 0110 and SW5[6]=0, then power on.
