| 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 |

| 5. COMPILER |
| ----------- |
| 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 |
