The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

Freescale Amadeus Plus M5253EVBE board ====================================== Hayden Fraser(Hayden.Fraser@freescale.com) Created 06/05/2007 =========================================== 1. SWITCH SETTINGS ================== 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.

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 codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
