1102. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
111===========================================
1122.1. System memory map:
113 Flash: 0x00000000-0x3FFFFFFF (1024MB)
114 DDR: 0x40000000-0x7FFFFFFF (1024MB)
115 SRAM: 0x80000000-0x8FFFFFFF (256MB)
116 IP: 0xF0000000-0xFFFFFFFF (256MB)
117
1182.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
119 linux kernel, you can customize it based on your system requirements:
120 Flash0: 0x00000000-0x00FFFFFF (16MB)
121
122 DDR: 0x40000000-0x4FFFFFFF (256MB)
123 SRAM: 0x80000000-0x80007FFF (32KB)
124 IP: 0xFC000000-0xFC0FFFFF (64KB)
125
1263. COMPILATION
127==============
1283.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or
129uClinux version) from codesourcery.com was used. Download it from:
130http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
131
1323.2 Compilation
133 export CROSS_COMPILE=cross-compile-prefix
134 cd u-boot-1.x.x
135 make distclean
136 make M5373EVB_config
