142. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
15===========================================
162.1. 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

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