- ==================
- 1.1 N/A
- 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
- ===========================================
- 2.1. 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:
- SDR: 0x00000000-0x00ffffff
- SRAM0: 0x20010000-0x20017fff
- SRAM1: 0x20000000-0x2000ffff
- MBAR1: 0x10000000-0x4fffffff
- MBAR2: 0x80000000-0xCfffffff
- Flash: 0xffe00000-0xffffffff
- 3. DEFINITIONS AND COMPILATION

- -----------
- To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
- compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
- You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
- compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
- codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
