3. COMPILATION
==============
3.1	To create U-Boot the gcc-4.x 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-1.x.x
   make distclean
   make M5475AFE_config, or	- boot 2MB, RAM 64MB
   make M5475BFE_config, or	- boot 2MB, code 16MB, RAM 64MB
