 113 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
 114 ===========================================
 115 2.1. System memory map:
 116         Flash:          0x00000000-0x3FFFFFFF (1024MB)
 117         DDR:            0x40000000-0x7FFFFFFF (1024MB)
 118         SRAM:           0x80000000-0x8FFFFFFF (256MB)
 119         IP:             0xFC000000-0xFFFFFFFF (256MB)
 120
 121 2.2. For the initial bringup, we adopted a consistent memory scheme between u-boot and
 122         linux kernel, you can customize it based on your system requirements:
 123         Flash0:         0x00000000-0x00FFFFFF (16MB)
 124         DDR:            0x40000000-0x4FFFFFFF (256MB)
 125         SRAM:           0x80000000-0x80007FFF (32KB)
 126         IP:             0xFC000000-0xFC0FFFFF (64KB)
 127
 128 3. COMPILATION
 129 ==============
 130 3.1     To create U-Boot the gcc-4.x-xx compiler set (ColdFire ELF or
 131 uClinux version) from codesourcery.com was used. Download it from:
 132 http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
 133
 134 3.2 Compilation
 135    export CROSS_COMPILE=cross-compile-prefix
 136    cd u-boot
 137    make distclean
 138    make M53017EVB_config
 139    make
