     14 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
     15 ===========================================
     16 2.1. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
     17 	linux kernel, you can customize it based on your system requirements:
     18 	SDR:	0x00000000-0x00ffffff
     19 	SRAM0:	0x20010000-0x20017fff
     20 	SRAM1:	0x20000000-0x2000ffff
     21 	MBAR1:	0x10000000-0x4fffffff
     22 	MBAR2:	0x80000000-0xCfffffff
     23 	Flash:	0xffe00000-0xffffffff

     95 5. COMPILER
     96 -----------
     97 To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
     98 compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
     99 You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
    100 
    101 compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
    102 codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
