Simon Glass 69d9eda4da i2c: Rename CONFIG_SYS_I2C to CONFIG_SYS_I2C_LEGACY 
It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and
CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less
than a year away.

Also we want to have a CONFIG_I2C for U-Boot proper just like we have
CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules.

Rename this symbol so it is clear it is going away.

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.

	http://www.arcturusnetworks.com/products/ucp1020

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

- 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

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
