+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
+	CFG_CLK			Define Amadeus Plus CPU Clock
+	CFG_MBAR		MBAR base address
+	CFG_MBAR2		MBAR2 base address
+
+3.2 Compilation

+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
+codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
