===========================================
2.1. System memory map:
Flash: 0xFF800000-0xFFFFFFFF (8MB)
DDR: 0x00000000-0x3FFFFFFF (1024MB)
SRAM: 0xF2000000-0xF2000FFF (4KB)

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
make M5475CFE_config, or - boot 2MB, code 16MB, Video, USB, RAM 64MB
make M5475DFE_config, or - boot 2MB, USB, RAM 64MB
