History

Tom Rini 4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them.

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
