+
+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:		0xFC000000-0xFFFFFFFF (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.x-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
+   make distclean
+   make M53017EVB_config
+   make
+
