2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
===========================================
2.1. System memory map:
Flash: 0x00000000-0x3FFFFFFF (1024MB)
DDR: 0x40000000-0x7FFFFFFF (1024MB)
SRAM: 0x80000000-0x8FFFFFFF (256MB)
IP: 0xFC000000-0xFFFFFFFF (256MB)
2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
linux kernel, you can customize it based on your system requirements:
Flash0: 0x00000000-0x00FFFFFF (16MB)
DDR: 0x40000000-0x4FFFFFFF (256MB)
SRAM: 0x80000000-0x80007FFF (32KB)
IP: 0xFC000000-0xFC0FFFFF (64KB)
3. COMPILATION
==============
3.1 To create U-Boot the gcc-4.x-xx 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
make distclean
make M53017EVB_config
make
