1112. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
112===========================================
1132.1. System memory map:
114 Flash: 0x00000000-0x3FFFFFFF (1024MB)
115 DDR: 0x40000000-0x7FFFFFFF (1024MB)
116 SRAM: 0x80000000-0x8FFFFFFF (256MB)
117 IP: 0xF0000000-0xFFFFFFFF (256MB)
118
1192.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
120 linux kernel, you can customize it based on your system requirements:
121 Flash0: 0x00000000-0x00FFFFFF (16MB)
122
123 DDR: 0x40000000-0x4FFFFFFF (256MB)
124 SRAM: 0x80000000-0x80007FFF (32KB)
125 IP: 0xFC000000-0xFC0FFFFF (64KB)
126
1273. COMPILATION
128==============
1293.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or
130uClinux version) from codesourcery.com was used. Download it from:
131http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
132
1333.2 Compilation
134 export CROSS_COMPILE=cross-compile-prefix
135 cd u-boot-1.x.x
136 make distclean
137 make M5373EVB_config
