The following config symbols are only defined once and never referenced anywhere else: CONFIG_AMCORE CONFIG_ASTRO5373L CONFIG_M52277EVB CONFIG_M5253DEMO CONFIG_M5253EVBE CONFIG_M5275EVB CONFIG_M54418TWR CONFIG_STMARK2 Most of them are config symbols named after the respective boards which seems to have been a standard practice at some point.

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
