History
Tom Rini 83d290c56f SPDX: Convert all of our single 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 a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
===========================================
2.1. System memory map:
	Flash:		0x00000000-0x3FFFFFFF (1024MB)
	DDR:		0x40000000-0x7FFFFFFF (1024MB)
	SRAM:		0x80000000-0x8FFFFFFF (256MB)
	IP:		0xF0000000-0xFFFFFFFF (256MB)

2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
	linux kernel, you can customize it based on your system requirements:
	Flash0:		0x00000000-0x00FFFFFF (16MB)

	DDR:		0x40000000-0x4FFFFFFF (256MB)
	SRAM:		0x80000000-0x80007FFF (32KB)
	IP:		0xFC000000-0xFC0FFFFF (64KB)

3. COMPILATION
==============
3.1	To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or
uClinux version) from codesourcery.com was used. Download it from:
http://www.codesourcery.com/gnu_toolchains/coldfire/download.html

3.2 Compilation
   export CROSS_COMPILE=cross-compile-prefix
   cd u-boot-1.x.x
   make distclean
   make M5373EVB_config
   make
