+2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
+===========================================
+2.1. System memory map:
+	MRAM:		0x00000000-0x0003FFFF (256KB)
+	DDR:		0x40000000-0x47FFFFFF (128MB)

+
+3. COMPILATION
+==============
+3.1	To create U-Boot the gcc-4.x compiler set (ColdFire ELF 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 M54418TWR_config, or			- default to spi serial flash boot, 50Mhz input clock
+   make M54418TWR_nand_mii_config, or		- default to nand flash boot, mii mode, 25Mhz input clock
+   make M54418TWR_nand_rmii_config, or		- default to nand flash boot, rmii mode, 50Mhz input clock
+   make M54418TWR_nand_rmii_lowfreq_config, or	- default to nand flash boot, rmii mode, 50Mhz input clock
+   make M54418TWR_serial_mii_config, or		- default to spi serial flash boot, 25Mhz input clock
+   make M54418TWR_serial_rmii_config, or	- default to spi serial flash boot, 50Mhz input clock
+   make
