Masahiro Yamada b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle 
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

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
