  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
