+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)
+	ATA:		0x90000000-0x9FFFFFFF (256MB)
+	PCI:		0xA0000000-0xBFFFFFFF (512MB)
+	FlexBus:	0xC0000000-0xDFFFFFFF (512MB)
+	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:
+	Atmel boot:
+	Flash0:		0x00000000-0x0007FFFF (512KB)
+	Flash1:		0x04000000-0x05FFFFFF (32MB)
+	Intel boot:
+	Flash0:		0x00000000-0x01FFFFFF (32MB)
+	Flash1:		0x04000000-0x0407FFFF (512KB)
+
+	CPLD:		0x08000000-0x08FFFFFF (16MB)
+	FPGA:		0x09000000-0x09FFFFFF (16MB)
+	DDR:		0x40000000-0x4FFFFFFF (256MB)
+	SRAM:		0x80000000-0x80007FFF (32KB)
+	IP:		0xFC000000-0xFC0FFFFF (64KB)
+
+3. SWITCH SETTINGS
+==================
+3.1 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
+	SW1 Pin4: 0 - ULPI chip not in reset state or 1 - ULPI chip in reset state
+	SW1 Pin5: 0 - Full ATA Bus enabled, FEC Phy1 powered down
+			  1 - Upper 8 bits ATA data bus disabled, FEC PHY1 active
+	SW1 Pin6: 0 - FEC Phy0 active or 1 - FEC Phy0 powered down
+	SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
+
+4. COMPILATION
+==============
+4.1	To create U-Boot the gcc-4.1-32 compiler set (ColdFire ELF version)
+from codesourcery.com was used. Download it from:
+http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
+
+4.2 Compilation
+   export CROSS_COMPILE=cross-compile-prefix
+   cd u-boot-1.x.x
+   make distclean
+   make M54455EVB_config, or		- default to atmel 33Mhz input clock
+   make M54455EVB_atmel_config, or	- default to atmel 33Mhz input clock
+   make M54455EVB_a33_config, or	- default to atmel 33Mhz input clock
+   make M54455EVB_a66_config, or	- default to atmel 66Mhz input clock
+   make M54455EVB_intel_config, or	- default to intel 33Mhz input clock
+   make M54455EVB_i33_config, or	- default to intel 33Mhz input clock
+   make M54455EVB_i66_config, or	- default to intel 66Mhz input clock
