1. SWITCH SETTINGS
==================
1.1 N/A


2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
===========================================
2.1. 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:
	SDR:	0x00000000-0x00ffffff
	SRAM0:	0x20010000-0x20017fff
	SRAM1:	0x20000000-0x2000ffff
	MBAR1:	0x10000000-0x4fffffff
	MBAR2:	0x80000000-0xCfffffff
	Flash:	0xffe00000-0xffffffff

3. DEFINITIONS AND COMPILATION
==============================
3.1 Explanation on NEW definitions in include/configs/M5253EVBE.h
	CONFIG_MCF52x2		Processor family
	CONFIG_MCF5253		MCF5253 specific
	CONFIG_M5253EVBE	Amadeus Plus board specific
	CONFIG_SYS_CLK			Define Amadeus Plus CPU Clock
	CONFIG_SYS_MBAR		MBAR base address
	CONFIG_SYS_MBAR2		MBAR2 base address

3.2 Compilation
	export CROSS_COMPILE=/usr/local/freescale-coldfire-4.1-elf/bin/m68k-elf-
	cd u-boot-1-2-x
	make distclean
	make M5253EVBE_config
	make

5. COMPILER
-----------
To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html

compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
